Are there any recommendations to prevent/clean up surface oxidation on the aluminum skins while you're building your airplane? Naturally, while you're working on it you're going to break a sweat and that sweat gets rubbed off on the airplane. Then, a day or two later a film of what appears to be oxidation forms on any place where sweat was left behind. I have rubbed and tried to polish the aluminum back up with a soft dry shop rag but it looks like the sweat has actually penetrated the alclad and has discolored the aluminum. Does anyone have any advice on how to deal with this?
