As the Neil Young song says, "rust never sleeps", but it slows down to a crawl in dry environments. The diaphragm probably is about as oxidized now as it will get. A thin oxide layer seems to prevent further oxidization of aluminum.
Aluminum is "dirty", as soon as it is cleaned more oxide develops, which is why it generally is not used for cooking. Fortunately, a bit of oxide does not hurt sound quality.
As an aside, the horns in stage monitors make good funnels, add some beer to a titanium diaphragm with an aluminum back cover and iron top plate (JBL 2445 driver) and interesting science fair crystals start to grow- those definitely needed to be cleaned to return the diaphragm to decent sounding status again ;^).
