It's most likely some kind of corrosion caused from oxidation (aka an oxide). For example, with iron (ferrous) based metals it's called iron oxide, commonly called "rust" and is a brownish-red color. On other metals, like aluminum, it is simply called aluminum oxide and is a whitish color. I *suspect* the "white stuff" is the corrosion of aluminum called "aluminum oxide". Could be wrong, but it's the simplest answer. Search Google Images for "aluminum oxide" and see if it's the same stuff. Happy corrosion hunting!
