Different manufacturers of car floor mats have their respective methods of cleaning. It is always best to refer to their manual on the proper care and maintenance of their respective products. Generally, however, rubber car mats can be easily cleaned using vacuum or even by removing these from the floor space and emptying any dirt or debris in a trash can. These can then be wiped clean with an ordinary rag or hosed down with water before being thoroughly dried. This is especially true if there’s dried up mud or stubborn dirt on the mats.
