I don't know if over cleaner works or not (but I suspect that it does). I can confirm that Red Devil lye will remove anodizing from aluminum parts. Just stripped a seat post. I need to go buy some Mother's polish tomorrow. I am going to strip my black stem as well before I build up the frame I just ordered.
