So I have this older knife that has been a little neglected lately and needs to be cleaned up. I've used Mother's on it for this very same problem in the past but I'm just wondering if there is something better. Also, is there anything I can use to clean the inside of the sheath with? I think that's where the problem lies.

I could wish a lot of things on my worst enemy but neuropathy ain't one of them.
