Acid treatment for deep pits?
I have a razor with several deep pits on the face of the blade, just below the spine.
I can get a dental pick into them, so I think that they are too deep to sand out,
without creating some pretty deep hollows.
I was wondering....Would an automotive "rust remover", which I believe is a mild
phosphoric acid, stop the progress of the pitting? I realize that the resulting oxide
would be black (ugly), but would it save the razor from further damage?
I've already gone over the pitted area several times with MAAS on a toothbrush,
with some removal of the black pitting, but not all. I thought I'd try that before
resorting to something more drastic.
Any comments please?
ps: I neglected to mention that the razor came to me already "repaired/restored",
so there's no etching or wash left on the blade worth saving.
