I have a chance to pick-up some used g-floor mats (sold at Sam's Club). I have seen this product discussed on GJ (and think the owner is a member). My question is what would you use to clean it?
Depends whats on it, really. If its just general wear and tear, hard to beat dish soap and warm water. I'd be wary of anything more heavy duty than that (concentrated simple green, purple power) as I've had it turn vinyl white and powdery.
