seems easy but with mine, 1 is worse than before. am affraid that i used too much acetone and the whole plastic became white. dont know how to fix it, if that can be done.
but is not a matter of sanding.
I think that acetone will improve the surface of the lens just so long as the oxidized surface has been removed.
The wire wooled surface will have a multitude of fine scratches on it and the application of the acetone to this surface momentarily dissolves the peaks on the surface which leaves the surface reasonably flatter and polished looking.
It will not do that to any oxidized surface material.
Polycarbonate lenses that have been moulded in polished dies are then exposed to a vapour bath of acetone which further refines the polished surfaces.
