I came upon this Mr. Clean product (via YouTube) while trying to find a method to remove those ugly scuff marks typically found on my modern autos sill plates. I was suspicious but there is really something about these pads. Whatever material they are made from, the pad just lifted scuffs marks off with the slightest effort and pressure. I simply wet the pad with water, sprayed simple green sparingly on the sill plate and my daily driver sills and seat surrounds are new looking again.
With success on my Silverado and the bride's Suburban, , I also tried same on the Packard seat surround too. Bright white once again I'm happy to write.
Just passing along my experience in case others should wish to try.
