Removing fire damage
 

Hi:

I bought a knife pistol (Peavey) that has some fire damage. It's intact mechanically but the blade has black stains. I tried polishing the stains out but all I have now are SHINY STAINS!

The blade is thin and brittle and I'd like to avoid agressive polishing / sanding to remove the stains. Is there any chemical treatment that would work?

Appreciate any help.

Anybody asks---tell them they are blood stains.

You can try bluing/rust remover.

Thanks for the input.

The bluing /rust remover might be worth trying. Any other thoughts out there?

I'v heard rumors around that using white vineger and rubbing the metal with aluminium foil removes stains on metal. Apparently they react and it creates a strong cleaning agent. However I'v never tried it.
Maybe a acid based bore cleaner might work? But be very carefull with that, its nasty stuff.

Thanks for the idea. I'll give it a try
