In addition to providing a cushion over another surface, rubber floor mats are popular because they are durable and not easily damaged. Rubber floor mats are also easy to clean and maintain. You are probably better off replacing a rubber floor mat that has become severely damaged and won't cost much money to replace. Repair floor mats that are more expensive with a rubber repair kit.
Use a garden hose to rinse off your mat and remove any loose dirt or debris.
Pour some household detergent into a bucket of water. Add enough detergent so the water is soapy.

Inspect the mat for stains or ripped and missing pieces of rubber.
