how would I clean bead-blasted ATS-34

[bdmicarta]

I have this old blade that has some stains on it. I don't know if this is gunk in the rough finish, stains in the metal or corrosion. I was thinking I would use toothpaste and an old toothbrush. This was my EDC for a good amount of time but I haven't carried it in 5 years or so.

Try the toothbrush and toothpaste.
If that doesn't remove it, use Barkeeper's Friend scouring powder. Mix it into a paste with water,and put an even coat of the paste all over the blade. Let is set for a few minutes, and rinse. Repeat if necessary.
