Other than cleaning them up, there is nothing you can do at home.
The comments about cold bluing are absolutely correct.
The only finish that would look good is rust bluing, but it's a long, tedious process. The chemicals are available from

I wouldn't touch the S&W-condition is too nice.
The .32 is another matter. You can have it properly refinished, or customized.
If you are going to refinish it, why not upgrade the finish to nickel, or hard chrome? Both hold up much better than bluing, and they cost about the same.
Refinishing a gun is not like refinishing furniture. There is much damage that you could do-so i implore you to have a professional do your gun(s.) They are quality firearms, that will be basically junk, if you start sanding and polishing them. It's really a job for an expert. After looking at the videos, I wouldn't suggest Larry Potterfield!
