I don't think you understand.
I can't think of any mechanism in anodizing that could do any more damage to a part than pitting it. Pitting is caused by a gross overcurrent condition, usually brought on by no current limiting. It's not like you can dissolve it or melt it or anything like that.
"Screwed up" in anodizing means lousy coating thickness/uniformity/pore structure, which will manifest itself by poor dyeing results. Stripping it off so that you can redo it is the dangerous part of the operation, and is where damage usually occurs.
A mixture of concentrated nitric and chromic (or is it phosphoric?) acids can dissolve the anodize without attacking the bare aluminum. But this nasty concoction is so hazardous to the operator, it is a case of the cure being worse than the disease.
