how to clean Kohler slip-resistant surface
I recently had a Kohler Villager tub installed. During the course of installation of the shower trim, wall tiles, etc. the slip resistant surface of the tub got dirty. I think it's mostly from the bottoms of the construction guys' shoes. I waited till all the construction was done before I attempted to clean the tub(about 2 weeks later). But now I cannot get all the brownish/grayish stains out. What do you use to clean your Kohler slip-resistant surface?
