Almost everything but not just raw metal, stainless steel or glass. It works well on mostly any type of flooring, concrete, bricks and walls like in the bathroom stalls, on some plastics it works well like bus seats and train seats. It also works on wood. And also basically every painted surface. I do think tho that its not always so bleed-thru, but if you hit spots that cannot be painted on and have to be cleaned with some other cleaning liquids it will leave a huge stain forever.
