In the past I've always used Turtle Wax chrome cleaner to shine up chrome plated parts, shells, lugs, etc. But I've heard a lot of jazz about simichome too. I have a project coming up with A LOT of grime and tarnish on the chrome...especially the shell which I would like to get poppin' again. Is simichrome the way to go? Does it really perform better than the other chrome cleaners/polishes out there?
