Hello List, My car has a perfect stainless steel door and one stainless rear 1/4 panel, the rest of the car is painted black. I was cleaning my R.O.H custom wheels with Turtle FORMULA 2001 foaming wheel cleaner. I wanted to see what it did on the stainless and it works GREAT! just spray on and wipe dry. It resist finger prints and really looks shiny. just wanted to let you all know. It works better than anything I have tried. I doubt it hurts the stainless, nothing really does. Later Dave #2496-black-not for long
