What Type of Brush to Use on SS

I'm curious, I recently found some rust on one of my stainless steel hammers. Should I use a copper brush like the one I use on my barrel or would something else work better.

Someone suggested very fine steel wool, but I'm afraid to go that far.

Any thoughts?

0000 steel wool and light oil. Wipe clean often.

"0000 steel wool "

Keep steel wool off stainless.
It will smear onto the surface and then rust.
A brass or bronze brush is just fine.

If you're positive the hammer is stainless steel, I usually use 1500 or 2000 grit fine wet or dry sand paper for polishing out sctaches and pits on my stainless guns. If it is not a collectable and a utilitarian gun such as most of mine are, I just polish them with the fine grit paper.

My company issued me a stainless Ruger once. It looked like someone had dropped it many times on pavement with gravel in it. I went to work polishing out the blemishes with 800 working my way to 2000 grit paper and ended up with the envy of that office. When I was assigned elsewhere, everyone wanted that pistol! (Of course I had put some very handsome, deep red exotic grips on it too, but they stayed with me.):D
