The best and easiest (all)metal polish I've ever used is BomsAway. It makes aluminum look like chrome if you work long enough. Much easier/quicker to use than any paste polish like mothers, eagle1, etc. Never-Dull cotton wadding is good too, but not as good as BomsAway on good cotton cloth (like Tshirt). A little bottle can easily last a couple years too.

Use oven cleaner to get off boot/rubber burns.
You can use 4-O steel wool and metal polish or even WD-40 to clean chrome, but you cannot press hard in polishing or you can/will leave swirls/haze. I have used it many times on tougher rust or corrosion, but you must let the wool do the work and not get impatient and press hard.... practice on out-of-sight areas first.
After wheel cleaner and soap and water, I use 4-O steel wool and BomsAway on my cruddy aluminum rims, then polish or polishing compounds on power buff wheels on a drill.
