I had them in my last truck. I already miss them. The new one will have them soon.

Simple green at full strength. Let it dwell on them for a bit and then scrub with a brush. Hose them off and dry them and then put some type of protection on them (be careful as a lot of the stuff make them slippery)

Forgot to ask this. Are the discolored spots generally lighter than the mat itself?
