We use these with great results around food preparation. What is the best way to clean them and are there ideal chemicals and/or processes to use?

The best way to clean our 3/4" Shock Mats is with our Rubber Floor Cleaner and Degreaser. You would apply this to your flooring with a synthetic mop head. If you don't have this cleaning solution, you can also use warm water and a mild soap solution. You would apply it the same way as the cleaner. You would first want to sweep and large dirt and debris and then mop the floor and air dry.
