Hi I just found some white floor mats that I would like to restore They have some dark stains, tar spots, and some yellowing. I have tried every cleaner I have in my collection and can't get beyond a certain point. The best results from Dura Gloss White Wall Cleaner, but not good enough!
Can you recommend something more powerful that will not dissolve the rubber mat?
