I tried this process last night, my main goal was to protect the gold wash.

1) it does remove probably all the rust but leaves a tough tarnish. MAAS can get the darkest part of the tarnish off, but if the blade was bad enough for rust to form you probably still need to sand it.

2) If you think that rust has formed on top of the goldwash then this process will remove the surface rust and reveal that the rust didn't form on top of the goldwash, but rather that the integrity of the goldwash was compromised and the rust rust is actually on the steel of the blade-even if 99% of the gold was looks perfect, the speckled rust you see translates to a speckling of compromised gold wash.

This should be obvious because gold never rusts. Unfortunately I didn't think about this when I recently purchased a slightly rusted razor because I really liked the near perfect (but slightly speckled) goldwash. (Luckily the razor is still a winner and has attractive etching!)

3) Left the celluloid scales on-no damage

4) Summary: Easy and cheap to do. Basically accomplishes removing surface rust with no effort and little time-this was the only benefit to me.
