Vinyl and most other types of resilient flooring don't need to be protected by waxing, but many floor care products include wax to brighten the shine. When wax builds up, it begins to discolor.

Discoloration that results from wax buildup is easily remedied. Use a solution of white vinegar and water or a cleaner specifically formulated for your type of flooring. Mop the solution onto the surface with a sponge mop and then rinse with clear water.
