If you're using Tarn-X, make sure you use the kind for SILVER PLATE, BTW.
I dunno about the airbrush comment. It might hurt the airbrush, itself.
How much metal would you remove with that, though?The only thing better is a brass wire brush wheel rotated at about 500 rpm and soapy water. Prepare to get wet when using this last method, but it produces a beautiful finish.

Hagerty Silver Polish is the most effective and safe tarnish remover I have used:

I have been very impressed with the MAAS (one syllable) line of metal polishing products. For bare brass especially, it shines better than Brasso and is much easier to clean up afterwards. It seems to be less abrasive than Simichrome or Flitz but does as just as good a job, if not better.
