Hey there guys. I just thought I would share this with you. This is an aluminum wheel cleaner for cars made by black magic. I applied it to a Bounty paper towel and smeared it on the aluminum areas of some of my Kirby's. I let it sit for a few minutes and then just wipe it off with a clean paper towel. It's not a drastic difference but I noticed that it does something. Perhaps it's more subtle then we even realize but I do notice that it tends to lessen the dark spots and it has a protective layer a film that leaves behind which I would think May inhibit oxidation. I got this at Wally World don't know if it is still made but I'm sure there are other aluminum wheel cleaners out on the market that would probably do the same thing.
