What is the best way to clean the black mat? Is there any treatment to keep it new looking?

To keep your 3/8" Heavy Duty Rubber Rolls looking like new, we recommend using our Rubber Flooring Cleaner and Degreaser. Adding mats to the entrance to where your flooring will also help keep dust and dirt from getting on the rolls as well. For any large dirt and debris, you will want to make sure you sweep or vacuum it up and then mop with our Rubber Flooring Cleaner and Degreaser regularly.
