GSF is using Ecolab’s No/Low Maintenance Flooring Cleaner and Protector to help schools safeguard modern floors


An increasing number of schools are replacing carpet flooing with luxury vinyl tile (LVT) and other low maintenance flooring in an effort to reduce maintenance, repair and associated costs. LVT is attractive to schools because it is marketed as requiring little to no upkeep, but the reality is that the flooring develops scuffs, scratches, and wear over time. Traditional flooring cleaners and treatments will not resolve these issues. Finding innovative solutions to these types of problems is a primary aim for both Ecolab and GSF USA, Inc, a global cleaning services company. Ecolab and its distributor partners have served as GSF’s primary chemical providers for more than five years, delivering tools, training, expertise and products that have forged a strong relationship and created positive outcomes for GSF customers.


Soon after schools within the districts that GSF serves began installing LVT flooring, the company noticed recurring dirt and wear in certain areas. “Everybody thinks that there’s no maintenance involved with these LVT floors, that you just put them down and don’t have to worry about it,” said GSF Branch Manager Steve Lusk, who oversees two school districts in the West Chicago area. “But we started noticing dirty traffic patterns, where it looked like the dirt was just grinding into the floors.” LVT floors are made up of several layers, including a clear “wear” layer at the top. Fine scratches in that layer, especially in doorways, hallways and other high-traffic areas, cannot be removed with traditional flooring cleaners or waxes.

GSF Branch Manager Grant Mackall said the floors could be cleaned, but they ultimately lost the sheen they had when new. Replacing floor sections would result in significant and unsustainable expense to the schools. But leaving the floors as they were would reflect poorly on the schools’ image. “We went to our supplier, North American Corporation, with the problem and they worked with Ecolab to deliver a  solution,” Mackall said.


Ecolab introduced GSF to a new product specifically designed to protect and maintain LVT floors, as well as laminate and other low-maintenance flooring. No/Low Maintenance Flooring Cleaner and Protector cleans and repairs minor scratches in these floors without adding gloss or a flooring finish. The solution fills imperfections in the wear layer, keeping floors looking new and protecting them from future wear and tear. The daily-use cleaner is easy to use, requires no additional training and can be applied with existing custodial equipment, whether it is diluted in a mop bucket or used in an auto floor scrubber. Following a demonstration of the product, GSF introduced it to schools with immediate success. No/Low Maintenance Flooring Cleaner and Protector quickly became the go-to solution for any school transitioning to LVT floors.


Upgrading to LVT flooring is a costly investment, one schools hope is worthwhile given the promise of less maintenance and repair. It’s GSF’s goal to help its partner schools protect their investment in modern flooring, and Ecolab’s solution is making that happen. “If schools didn’t have a solution like this, one that’s not only cleaning, but also repairing the floor, they’d be looking at replacement costs,” said Ecolab Technical Account Manager Chris Walter. “And the replacement costs would be astronomical.” It’s estimated that average daily cleaning using a basic cleaner and floor finish would result in twice the flooring repair costs compared with using No/Low Maintenance Flooring Cleaner and Protector alone.

How a school looks is important to students, parents, and faculty. GSF and Ecolab have also been able to help deliver an image everyone can be proud of. The companies have received overwhelmingly positive feedback from schools utilizing No/Low Maintenance Flooring Cleaner and Protector. Lusk called it a game changer. “Before we started using the product, you didn’t see that sheen tile floors should have,” Lusk said. “Now with the restorative capabilities of No/Low Maintenance Flooring Cleaner and Protector, floors definitely have a natural sheen and it lasts longer.” GSF expects the need for the product to rise as LVT continues to become more popular. “It’s nice that we’re able to take No/Low Maintenance Flooring Cleaner and Protector to a school with luxury vinyl flooring and utilize the product to help them maintain and protect their investments,” Mackall said. “We’ve found it to be a great product.”

The Heart of GSF USA

At GSF USA, our heart lies with our staff members who keep our company going and our customers happy. We hire individuals who not only embody our vision and goals but continuously seek growth and career development opportunities. Studies show that companies that prioritize employee satisfaction and engagement are 21% more profitable than their peers. When your employees feel good about coming to work, it reflects the culture of the company and the work that is done.

One of GSF USA’s more recent clients, Germantown School District, which is comprised of four elementary schools, one middle school and one high school, chose GSF USA to maintain their schools and help prioritize the health and safety of those who enter it daily. “Germantown School District chose GSF USA because of our strong culture and ability to grow and develop our people. They were drawn to our innovative approach to chemistry and technology and the trust they’ve built from our work in multiple other school districts. Simply put, we deliver on what we say we’re going to do,” said Vice President of GSF USA, Kurt Kuempel.

There are so many roles to fulfill at GSF, each one offering opportunities for growth and advancement. When asked about his role as GSF’s Wisconsin Branch Manager, Mark Streitmatter said, “My favorite part about my job is that every day looks different. I get a chance to train and develop people while promoting to our team that this is more than just a job; it’s an opportunity to have a career.” A chance to advance in the workplace is important, not only for employee retention rate but also to help motivate people to want to expand their skill sets. At GSF USA, over 50% of Operations Managers were developed and promoted from within the company.

Another client, U.S. Cellular Plaza, chose GSF USA because of how its team structure stood out from other contractors. Creating a culture of employees that love what they do and show it through their work is an added value that customers appreciate. “GSF’s culture is unique in the industry because we empower our teams to be able to do the work,” said Kuempel “, We spend a lot of time training and developing at ‘GSF University’ and teaching them to be held accountable for the work that they do every day.”

Providing high-quality and sustainable cleaning solutions is at the core of GSF USA’s mission. This means that employees prioritize being well-trained in how to professionally clean each area, use cleaning equipment and supporting one another to ensure that the facilities they work in are getting the services they need. “Sustainable cleaning is important to our customers, so they know they’re coming into a building that has everything from good indoor air quality, to being properly clean and disinfected and creates a welcoming environment,” said GSF’s Director of Educational Services, Scott Mackall.

Our employees’ stories show that at GSF USA, we stand behind our mission. We view our staff as more than just people we hire, but as a team that we care for, support and want to help grow. Offering educational programs, onsite training and advancement opportunities is just the beginning of the core of our values and the heart of our company. Want to join our team? Check out our job openings!



Germantown School District in Wisconsin is comprised of four elementary schools, one middle school and one high school as well as Germantown Virtual School for students grades 6-12 living in the state of Wisconsin. More than 3,700 students are enrolled at the district, which has a goal to “Empower and Inspire Every Student to Success.”

The COVID-19 pandemic led to increased cleaning and disinfecting and the use of new equipment like electrostatic sprayers to address SARS-CoV-2. However, many conventional cleaning chemicals contain ingredients that can create unsafe conditions for cleaning professionals, students, staff and visitors. Germantown School District began looking for a better way to clean that would adequately protect against pathogens of concern while also prioritizing occupant safety and environmental sustainability.


Germantown School District selected GSF USA, a global cleaning services company, to oversee its cleaning program. GSF’s Green Seal®-certified Écologique cleaning program swaps traditional and potentially caustic cleaning chemicals with safer electrochemically-activated solutions (ECAS) from PathoSans®. ECAS are made with an on-site generation system using salt, water and electricity.

PathoClean® is a cleaner/degreaser and PathoCide® is a sanitizer/disinfectant. GSF USA operates two generators and 15 satellite units across the district’s buildings. Employees fill spray bottles with the cleaner and disinfectant. Staff can also safely use the disinfectant with equipment like electrostatic sprayers to quickly disinfect classrooms, hallways and bathrooms.

“Switching from multiple cleaning chemicals to two easy-to-use solutions from PathoSans greatly streamlines the cleaning and disinfecting process,” said Mark Streitmatter, Branch Manager, GSF USA. “The two solutions take care of the majority of the cleaning needs of the district and do not create safety risks because they are made with three simple ingredients.”


With the help of GSF USA and PathoSans, Germantown School District can be confident in:

Cleaning performance. The PathoClean cleaner has reduced the buildup of detergent residue on surfaces throughout the school that are common when using traditional cleaning chemicals. Meanwhile, the fast kill time of the PathoCide disinfectant helps GSF’s employees quickly yet effectively disinfect surfaces. The two products enable GSF to clean for health and appearance, making Germantown School District inviting and safe.

Good indoor air quality. Many cleaning chemicals release volatile organic compounds (VOCs) into the air and cause eye and lung irritation. The district previously had to have a separate disinfectant that was compatible with electrostatic sprayers, since the droplet size can impact health and safety. Now, the school has two solutions that are compatible with all surfaces and equipment, do not contain added fragrances or other caustic ingredients and do not emit VOCs. This supports better indoor air quality (IAQ).

Stable chemical supply. The PathoSans solutions are produced in house and on demand with easy-to-source ingredients. This means GSF will always have readily available supply of cleaner and disinfectant, eliminating any disruptions in the cleaning process.

Its commitment to sustainability. Because the PathoSans solutions are made up of water, salt and electricity, they are not harmful to the environment. Additionally, eradicating the shipment of cleaning chemicals to the district’s buildings eliminates the greenhouse gases associated with the transportation of these supplies.

“We’ve been impressed with the never-ending supply of cleaner and disinfectant that the PathoSans generators provide,” added Streitmatter. “The system makes inventory management much easier, as we just need to ensure that we have salt at the ready to continue producing the electrochemically-activated solutions.”

Tips for Onboarding New Cleaning Professionals

New hires are always an exciting addition to a facility. While most employees usually come with skill sets and prior knowledge of their own, it’s still important to help them learn the ropes and set them up for success. Every facility runs differently, making the first few weeks a critical time to assist new employees and familiarize them with what expectations they need to meet. This provides them with support as they transition into a new job and ensures that as a facility manager, you clearly state the cleanliness standards. Here are three tips for successfully onboarding new cleaning professionals.

Familiarize with Cleaning Procedures

Every facility has its own cleaning procedures and protocols that they follow. Even if your new employee has previously cleaned professionally, it’s still important to share with them how often the facility needs to be cleaned and the specific cleaning procedures for your company. If your facility is smaller, there may be tasks that only need to be done weekly or monthly. On the contrary, there may be tasks, such as taking out the garbage or mopping floors, that need to be done daily. It’s also helpful to share with your new employees the specific cleaning methods that the facility follows. For example, if you have a morning maintenance crew that is designated to restock the restrooms while the night-time maintenance crew is designated to clean the restrooms, that should be relayed to new employees to keep a steady routine in place.

Learn the Facility

Take time to help your new employees get comfortable with the facility. Especially if it’s a large facility, it will be useful for them to know where supply closets are, how many restrooms there are, the best times to clean certain rooms and which parts of the building they will need to focus on cleaning. Providing them with a map of the facility or a cleaning route can help familiarize them with the layout. It may also be helpful to have new employees shadow employees who have more experience. With any new job, it takes time to learn the ins and outs of the building, as well as where things are. However, it’s important for cleaning professionals to know the layout of the facility to ensure that they aren’t accidentally skipping over critical areas.

Equipment Training

Facilities use different cleaning equipment and products depending on the type of flooring they have, what tools are appropriate for the building and the types of chemicals that can be used. Make sure your new employees know where to find the equipment they may need to clean, how to maintain that equipment and how each piece of equipment should be used. Misuse of cleaning equipment or mixing the wrong chemicals together can lead to facility damage that becomes costly to repair. Providing all your employees with proper training in equipment usage can help to avoid injuries, damage and ensure that a proper job is done each time.

Providing Initial Support

Taking time to help successfully onboard new employees helps them feel welcomed and more confident in their role and  allows facility managers to set expectations from the beginning. When employees are provided with a strong support system, it reflects in the work they do and leaves a lasting impression on customers.

Implementing Sustainability in the New Year

A new year comes with new hopes and goals. For businesses, this means thinking of ways to find new opportunities for growth and improvement in the workplace. In recent years, working toward more sustainable and greener practices is one that numerous businesses have felt is an important step to take in improving not only their work environment but also their business and relationships with customers. Recent studies have found that consumers look for businesses that take responsibility for environmental practices. Start 2023 green with these tips on implementing sustainability in the new year:

Part Ways With Plastic

Around 380 million metric tons of plastic are produced yearly, which accounts for over 27 million tons in landfills. Reducing the amount of single-use plastic being used in the workplace is a small but significant way to practice sustainability. You can start by providing a water cooler or company-affiliated water bottles to reduce the number of employees bringing in plastic water bottles. If you are a retail store, opt out of using plastic shopping bags and instead use paper bags and encourage customers to bring their own bags. Many stores have started charging shoppers who request plastic bags. Another way to reduce single-use plastic is by working with suppliers who use less plastic when distributing materials to your facility.  Partner with companies that make sustainably conscious decisions like PathoSans and GSF USA, who are mindful of reducing plastic usage when cleaning facilities by utilizing refillable bottles for cleaning.

Clean with Green

Most conventional cleaning products are made from toxic chemicals that are harmful to the environment. Switching to eco-friendly cleaning products is not only better for the environment but also for your business. Using sustainable cleaning products can save money, as many sustainable cleaning products are made to last longer and work more effectively than conventional cleaning products. Although the products may be more expensive up-front, in the long run, you will save more money. Sustainable cleaning products are a much healthier alternative to eliminate dust, allergens and germs. It can also improve air quality, being a safer solution for employees and guests. Investing in a sustainable cleaning program is another time and cost-saving solution as you can prioritize your work while cleaning professionals focus on creating a healthy and clean environment using sustainable practices.

Encourage Change

Discuss with your employees that the health and safety of themselves, as well as customers, is a top priority in the workplace. This starts with creating sustainable practices that benefit not just the people in it, but also the environment. Encourage employees to increase recycling. Implementing incentives for employees who go above and beyond to practice sustainability in the workplace is a fun and creative way to get everyone involved. Encourage going paperless to reduce the amount of waste in the office by implementing e-notifications and updates. The usage of hybrid work settings was originally put in place during the peak of the COVID-19 pandemic but is still being used today. In fact, 74% of businesses are planning to remain hybrid moving forward. Hybrid work settings have been found to be an environmentally friendly solution to five-day work weeks by reducing daily transportation to and from the office.


Implementing sustainability in the workplace has become a social responsibility for companies. As consumers pay more attention to brands and businesses that acknowledge the importance of working toward a greener future and act by making company changes, it is now more important than ever for businesses to take action in doing so. Small changes can lead to a big impact. By working together to make environmentally conscious changes today we can see a better and healthier tomorrow.

Reducing Resource Consumption in Your Cleaning Program

When it comes to running a successful business, keeping your facility up to date with cleanliness and safety standards should be a critical priority for the wellness of your employees and guests. This includes having regular cleaning protocols, product and equipment restocking, and services that help maintain your facility. However, keeping a facility exceptionally clean and maintained can quickly add up in cost, inventory space and time. Here are some ways to keep your facility clean while reducing resource consumption.

Tips on Reducing Resource Consumption

Hiring a team of cleaning and maintenance professionals to clean can be a great solution to ensure your facility is regularly maintained while being cost-effective and saving inventory space. On average, businesses spend between $63 to $200 on cleaning supplies each month. While for some companies, that may not seem too significant of a difference, over time, that adds up to a large sum of money that could be used to benefit your business in other ways. Hiring a cleaning service that brings its cleaning supplies and equipment can also save inventory space that would otherwise be taken up by needing to restock cleaning and maintenance items regularly. Many cleaning services can set up customized schedules depending on how often you need your facility cleaned, relieving the stress of ensuring your facility is up to date with its cleaning procedures.

If you prefer to have facility cleaners from your company internally, make sure you invest in high-quality, sustainable cleaning products and equipment. Often, companies will opt to purchase cheaper cleaning supplies to save money. However, when surveyed, approximately 40% of respondents stated that they spent between 21-40% of their operating budget on cleaning /maintenance equipment and supplies. When you purchase low-quality materials from your facility, the results show. Over time, the breakdown and wear of cleaning equipment and the surfaces they’re being used on build up, which means you spend more money on replacing equipment, flooring, surfaces and other facility essentials.

Go green! When surveyed, more than half (58%) feel their office is ‘shamefully eco-unfriendly,’ with one-third (34%) believing the introduction of eco-friendly practices within their workplace is usually an afterthought. Not only does a higher rate of resource consumption cost a company more money, but it also reflects poorly on the conscious efforts to provide a sustainable and environmentally friendly workplace. Investing in eco-friendly and sustainable products benefits your workplace and reduces consumption waste that negatively impacts the environment.

Benefits of Reducing Resource Consumption

One of the most significant benefits of reducing resource consumption is building a more substantial company reputation and gaining business. When surveyed, a majority (77%) of Americans prefer to purchase from brands that prioritize efforts to fight global warming. Making conscious efforts to reduce waste at work, providing a facility that runs on sustainable practices and investing in business practices that benefit the environment, helps reflect to consumers that, as a business, you care more about creating healthier and greener solutions than choosing unsustainable practices in order to benefit financially.

Another substantial benefit is creating a healthier work environment for employees. In fact, a Harvard Business Report found a strong correlation between the physical workplace environment and employee performance. When employees don’t have the added stress of needing to ensure their facility is being properly maintained and cleaned, this allows them to focus more on getting productive work done. It also encourages workplace morale, as employees are more likely to come into the office when they feel good about the environment they work in as opposed to working from home. This allows employees to build stronger relationships and make substantial use of the facility.

Aside from the benefits that reducing resource consumption provides for your facility, employees and occupants, it also greatly benefits the environment! A study found that billions of liters of chemicals and supplies are used for cleaning purposes each year. The results of this are that between 80,000 and 140,000 chemical contaminants from cleaning products can be found in our wastewater. Investing in high-quality green products and services that use gentler and more sustainable results leaves fewer toxins and pollutants in the air and plastic waste in our landfills. When you consider the future of your business, keep in mind that the future of the economy and environment plays a significant role.

Reducing resource consumption can be achieved in various ways. However, the results all show the same positive outcomes. Being mindful of the state of your facility, the health and safety of your employees and guests, as well as the future of our environment speaks volumes of a company’s priorities. Help the long-term future of your business thrive by choosing high-quality and sustainable options when it comes to resource consumption.


Overlooked Areas in your Building that Need to be Cleaned

As most businesses and schools return to an in-person setting, it’s now more important than ever to ensure that workplaces exceed cleanliness and sanitation standards. Most facilities have custodial teams or management who keep up with a consistent cleaning routine. However, there are still many areas in shared public spaces that get overlooked or forgotten about during a maintenance routine. This leads to a build-up of germs and bacteria that over time can lead to more significant health risks, structural damage to the building, or an increase in infection and disease transmission. Learning how to properly clean and disinfect shared spaces such as offices or classrooms can help improve the overall safety of your employee’s and guest’s health, create a welcoming environment for occupants, and keep buildings in excellent condition.

The Most Overlooked Areas for Cleaning in Offices

The most common places that get skipped over while cleaning is under office chairs, office furniture, vents and ducts, office computers, telephone, lights, curtains, and microwaves.

There are various factors that determine how frequently an office should be disinfected and cleaned. This includes office size, employee size, and how often occupants are inside the building. The types of companies you share the facility with will also make a difference. For instance, if one of those other businesses is a doctor’s office or a similar medical facility, you will need to schedule deeper daily cleanings for that space to keep patients healthy. The same holds for any facilities that have children, such as schools or tutoring areas. Children quickly spread germs among themselves and keeping the areas where they learn and play clean can help prevent outbreaks.

62% of employees say simply seeing sanitation professionals regularly at their workplace would make them feel safer.

Strategies to Implement a More Thorough Cleaning Routine in the Office

Know the difference between disinfecting and cleaning, and how often each one should be done. Often, the terms are used interchangeably. However, each term serves a different purpose and impacts the cleanliness of your facility. This previous blog from our team at GSF USA breaks down the differences between disinfecting vs cleaning and how both should be properly done in the workplace.

Hire a professional cleaning service that can sanitize an office space using the right equipment and procedures. Our carefully developed Écologique cleaning program is certified by GREEN SEAL® and offers the highest standard of cleaning while also considering the environmental impact at every step of the cleaning process.

Have the right cleaning and sanitation tools easily accessible to ensure that quality cleaning is being done on a regular basis.

What Does a Proper Cleaning Routine Look Like in The Office?

Consistency is a significant factor when it comes to your facility’s cleaning routine. Skipping out on everyday maintenance such as wiping down commonly touched surfaces and spaces will lead to a buildup of unwanted germs and bacteria. While certain tasks like floor and window cleaning can be done less frequently, by establishing a routine that is consistently followed you can help reduce the spread of illness in the office, as well as maintain a nice-looking appearance to guests.

To save time and ensure your facility is being thoroughly cleaned and disinfected, hiring an outside source to come and get the job done can be a practical solution. Cleaning and maintenance professionals are experienced in knowing what tools and products to use, how to use them, and what areas are often missed while cleaning facilities. Services like our team at GSF USA are dedicated to creating a clean and safe environment for occupants to work in.

Know when to increase your cleaning and disinfecting. During cold and flu season, up to 74% of employees in the U.S. miss work due to being sick. Keeping the workplace regularly clean and disinfected, as well as communicating to employees to practice hygiene practices such as regular handwashing and keeping their workspaces clean can also make a significant impact on reducing illness and missed days of work.

We Care About Clean

At GSF USA, we understand that having a clean and safe environment is a crucial part of running a successful facility. That is why we offer a variety of services and products that ensure quality cleaning in your facility. The safety and health of your occupants should always come first, and that starts with a clean workplace.

Located at 8420 West Bryn Mawr Avenue in Chicago, U.S. Cellular Plaza is a Class A building that comprises three buildings totaling 637,000 square feet. Managed by Colliers, a global commercial real estate services firm, the ENERGY STAR rated property features numerous amenities, including a conference facility, fitness center, delicatessen and 24-hour security service. 

While many tenants transitioned their employees to remote work during the COVID-19 pandemic, leading to lower foot traffic at U.S. Cellular Plaza, Colliers understood that the property needed to maintain the highest levels of health and safety for occupants and visitors. 

The firm placed hand sanitizing stations in common areas, restricted elevator capacity to four people and required mask wearing in shared spaces like hallways and lobbies. It also sought a way to enhance the standard of cleanliness across the buildings. 

“First impressions are important. We want tenants and visitors to see a visibly clean environment,” said Kelly Conkle, Assistant Property Manager, Colliers. “The pandemic expedited our search for better cleaning with better machinery.”


Colliers turned to GSF USA, a leading provider of commercial cleaning services that implements its sustainability-focused Écologique cleaning program in commercial offices and schools. In addition to focusing on documented training and leadership development, the program prioritizes the use of safer chemicals and high-tech equipment. 

“The pandemic has caused many companies to look at cleaning differently,” said Kurt Kuempel, Vice President, GSF USA. 

GSF educated Colliers about the electrochemically-activated solutions (ECAS) it uses to clean and disinfect its customers’ buildings. The solutions from PathoSans are created with an on-site generator using salt, water and electricity. They are non-irritating and don’t contain added fragrances or volatile organic compounds (VOCs) that negatively impact indoor air quality (IAQ).

GSF also implemented new equipment, including e-mist sprayers to quickly and easily disinfect, HEPA-filter vacuums and a T350 Stand-on Floor Scrubber from Tennant equipped with the ec-H2O NanoClean® system, which electrically converts water into an innovative, detergent-free, solution.


With the help of GSF USA, Colliers and U.S. Cellular Plaza realize the following benefits:

Safer cleaning. Conkle says: “Many tenants’ employees are sensitive to harsh chemicals. We do not want anyone to have a reaction or be uncomfortable because of a harsh cleaner being used throughout our complex.” Using ECAS instead of harsh chemicals to clean and disinfect means that GSF’s employees and building occupants are not being exposed to any harmful or irritating chemicals. 

Enhanced floor care. The cleanliness of floors can influence first impressions upon entering a facility. GSF’s day porters and evening crew regularly use vacuums to maintain the appearance of carpet and hard flooring throughout the buildings. Additionally, the team utilizes a Tennant floor scrubber to increase productivity while thoroughly removing soils. According to Conkle: “The floorcare machines have been helpful. We believe the addition of better equipment will help to improve the cleaning quality.” 

“We are proud to oversee a sustainable cleaning program at U.S. Cellular Plaza,” added Kuempel. “We look forward to supporting Colliers as an increasing number of tenants bring their employees back to the office.”
