Hi Mark I suggested he use aluminum wheel cleaner to clean the aluminum under his hood, not his painted wheels.

I'm not 100% convinced it isn't galv. corr. I've seen aluminum heat sinks inside closed electronic devices that have that white powder on it, as well as pitting. This type of corrosion can happen to aluminum if there is a high voltage leak close by. There is another theory that over time a type salt leaches out of some aluminum. Don't know about that though?
