since there were some questions and suggestions in the other thread, I figured I could start a new thread here on it for tips and suggestions.

I just read online that a little bit of brake cleaner or carb cleaner can really brighten up the aluminum. You'd have to be careful of your painted areas with the brakekleen spray however. I haven't messed around with my cast aluminum parts yet this year but last spring I had good luck with some Simple Green & a rag/toothbrush...

I wonder if cast aluminum wheel cleaner spray would work alright? Anyone try this?
