Floor mat cleaner is a specialized detergent formulated to tackle the heavy grime found on vehicle floor mats. For rubber mats, it dissolves dried mud, oil, and tar, restoring the deep black matte finish without leaving a slippery residue. For carpeted mats, it acts as a spot remover to lift stains from shoes and dirt. It usually contains stiff scrubbing agents. Regular cleaning prevents the buildup of mold and bad odors that rise from damp mats.
