I dont know what that coating was on my copper mugs but thinner and paint stripper didn't do a thing to it, I left one in a sealed can of acetone overnight...nothing.

I sprayed on the oven cleaner waited five minutes and rinsed it off...then cleaned it with mild phosphoric acid wash...good as new.

Maybe aluminum is much wimpier than copper?
