Cleaning Regime Impact on PTV

How cleaning affects PTV

Several cleaning-related effects reduce PTV over time:

• Polishing — abrasive cleaning machines or polish-loaded products gradually fill or smooth the surface texture engineered into the floor
• Residue accumulation — under-rinsed detergents leave a thin film that affects friction, particularly when re-wetted
• Chemical attack — strong caustic or acidic regimes can degrade the engineered surface chemistry of vinyl, resin and some tile finishes
• Sealer wear — protective sealers worn off through cleaning expose a different (sometimes lower-friction) underlying surface
• Saturation cycles — repeated wet-mop cleaning without adequate drying alters surface biology over time, particularly external paving

The 'day one vs day seven' problem

One of the most reliable findings in service-environment pendulum testing is a floor that meets specification immediately after a deep clean but fails several days into the cleaning cycle as polishing-style products accumulate. The post-clean PTV is not the PTV that customers and staff actually walk on. Testing toward the end of the cleaning cycle, not immediately after, captures in-service performance.

Documenting the regime alongside the test

For risk-management and claim-defence purposes, the cleaning regime should be documented alongside the pendulum data:

• Products in use, by name and dilution
• Frequency and method (mop, machine, manual)
• Rinsing protocol
• Drying time and protocol
• Whether testing was carried out post-clean, mid-cycle, or pre-clean

This converts the pendulum data from a static number into a contextualised performance measurement.

Working with cleaning contractors

Where the cleaning is outsourced to a third party, the contract may not specify a slip-performance requirement — only a cleanliness requirement. Pendulum data identifies where the contracted regime is producing a side-effect on slip performance, and supports either a contract variation or a cleaning-product change.

Specific problem product categories

• Spray-and-buff polish products on textured vinyl or tile
• Crystallising waxes on engineered slip surfaces
• Quaternary ammonium disinfectants left to dry without rinsing
• Strong alkaline degreasers in food-prep environments without thorough rinse
• Sugar-based foam cleaners that leave residue
