I bought a jug of WD-40 Rust Removal Soak and it works fantastic on tools. I let a couple of old pliers, wrenches and chainsaw spark plug wrench soak overnight and all the rust is gone. Much better and less caustic than Navel Jelly but only for soaking I think. You can paint Navel Jelly on a large part.

I would like to try it on a blued gun part as it says it is safe for everything and it biodegradable, re-usable, non-corrosive etc. I would like to test it to see if it is safe for blueing.
Does anyone have a junk, rusted part of any type from a blued gun? Pin, slide stop, old sight etc? Doesn't matter what. I'll pay shipping and return the part if you want it back.
Thanks.
