Remove Lead (i.e. Pb) marks from an enamel bathtub?????




Would anyone have any suggestions on how to remove lead rub marks on an
enamel surface. There were lead weights on the inside of my shower liner
that have created marks over time when they flipped around due to the
billowing of the liner. Nothing I have used has worked.


Tried and Failed:

1) Dremel Moto tool with felt polishing wheel
2) Comet
3) Gojo abrasive hand cleaner

I didn't rub too hard with any of the solutions for fear of damaging the
surface.


Ideas:
1) heat gun + abrasive
2) Dremel felt wheel + abrasive
3) Chemical???

Apart from using aqua regia or hydrofluoric acid, is there anything that
would attack the lead without destroying the enamel?

Any ideas would be much appreciated.

Notes:
It is a metal tub with a, presumably, enamel surface.
