I made up my own polish from a couple of small polishing bars I bought at HF, mixed it with paint thinner and put a nut in the bottle of the bottle to agitate it and get the solids back in suspension after it has set for a while. When I started I had about a half bottle of the mix shown attached. I got the idea of the web when I was looking into aluminum polishing tips. Apply with a small soft cotton cloth and wipe off with cotton or microfiber.
Don't use steel wool. It may look good immediately but your scratching the chrome up and embedding carbon bits from the wool into the chrome so sure to rust again quickly.
Maybe half a bar of this green:

Some before and after Pictures below and it didn't take much time at all to do it! Does it color again, yes but easy to clean. Subsequent times aren't bad at all to keep it looking good.
