Nope its not, not if it is chrome or nickle plate (which is rock hard). SOS pads have polish in them and the steel wool (which is ultra fine) rides on a film of polish. The polish is what does the work.
Collinite insulator wax is the best, longest lasting wax I have ever used. Highly recommend their products.
For beater quality stuff, I soak parts overnight in white vinegar . An easy scrub and a rinse in a soda water solution to neutralize. The difference is dramatic. Then I shoot it with a "...goes on clear, turns to black" rust converter primer (does not discolor the good chrome). Before....and after!
I can see how CocaCola works because it has Phosphoric acid in it but how does the aluminum foil not scratch the chrome? Hmm i may need to try this
