The relationship between cleaning methods and slip resistance
Incorrect cleaning is one of the leading causes of slip-and-fall accidents on commercial floors.
What you are looking at
- Residue from cleaning agents is a major slip hazard.
- Proper rinsing is essential to maintain original slip ratings.
- The 'pendulum test' is the standard for measuring slip resistance.
- High-gloss finishes aren't always slippery, but they must be maintained.
- Contamination (oil/water) interaction with the floor is critical.
- Cleaning method changes should be reflected in your risk assessment.
- Documented cleaning records support liability protection after an incident.
Safety is the highest priority for any site manager. While a clean floor is generally safer, the process of cleaning—and the residues left behind—can significantly alter the slip resistance (Coefficient of Friction) of a floor.
Using the wrong chemical or failing to rinse properly can turn a safe vinyl or stone floor into a skating rink when wet.
Cleaning methods and slip resistance also need to sit alongside your site's existing risk assessment, since a change in cleaning approach can affect the figures that assessment relies on.
Keeping this documentation up to date protects both your staff and your organisation should an incident ever occur.
Why businesses ask us for this
- • Residue management is key to slip safety.
- • Deep cleaning restores the grip of safety floors.
- • Correct chemistry prevents 'soapy' surfaces when wet.
- • Cleaning changes should be checked against your risk assessment.
- • Keep dated records of methods and products used.
- • Coordination with your safety team protects both staff and the business.
The danger of soap residue
If cleaning solution is not fully extracted or rinsed, it dries into a thin, invisible film. When a drop of water hits that film, it reactivates the soap, creating a dangerously slick surface.
We use neutralisers and thorough extraction to ensure that no surfactant residue remains on the floor.
Maintaining the texture
Safety flooring (like Altro or Polyflor) relies on tiny abrasive particles to provide grip. If these become 'filled in' with dirt or wax, the floor loses its safety rating.
Restorative deep cleaning is required to clear these particles and return the floor to its designed slip resistance.
- Removal of greasy films
- Cleaning of textured 'safety' floors
- Neutralising soap residues
- Verification of drying times
Safety during the clean
The cleaning process itself is a high-risk period. We use clear signage, physical barriers, and high-speed drying to ensure that the risk to your staff and visitors is minimised.
Working with your existing risk assessment
If your site risk assessment references a specific slip-resistance rating, any change to cleaning products or methods should be checked against that rating to ensure it still holds true.
Keeping dated records of cleaning visits, products used, and any pendulum test results provides valuable evidence should a slip incident ever be investigated.
We can work alongside your health and safety team to ensure our cleaning approach supports, rather than undermines, the assumptions built into your existing risk documentation.
