First, add one cup of fabric cleaner to every half bucket of water used for cleaning. This will make the rubber floor look like it's newly waxed.
Second, using a multi-purpose cleaner solution is very effective for cleaning rubber floors. Carefully read the precautions on the product label first, and it's best to test it on a corner of the floor before use.
Third, to remove footprints from rubber floors, use a high-quality steel wool dipped in liquid floor wax to gently scrub away the stains, then wipe dry with a damp cloth.
Fourth, regularly remove accumulated wax with a cleaner or wax remover.
Fifth, solvent-based products may soften and damage rubber floors.
Sixth, never rinse the floor with water; too much water will cause the adhesive to peel off.
