lol, you talking about the acid dealerships once used on the engines and wheels?

Take any liquid degreaser, water it down at least 50%, and spray it on...greased lighning, simple green, or whatever. The foaming spray stuff like Gunk works well to, I've used it on tons of things before but not on my current vehicle...no way to dilute it and i'd go nuts if it discolored the aluminum.
