Alcohol or acetone for corrosive primer residue

[Unka-Boo]

The important takeaway here is that only WWII rifles can fire corrosive ammunition.

Don't tell my AK that...

Most beat to death subject in the internet...
Residue is corrosive salt ( potassium chloride, IIRC)
Water dissolves it.
Use HOT water to flush barrel, rinse bolt, follow with your favorite bore cleaner and lightly oil when done.

Alcohol and acetone wont do a thing for it.

I can contribute too! Let me just bump the post count one more time. . .

Potassium Chloride and sodium chloride are insoluble in both acetone and alcohol. The two will rinse off the salts, but only through mechanical means. Hot water will actually dissolve the stuff, which is far better for removal, especially if the salts are stuck on to the surface.

Ammonia (Windex) does nothing to assist with the process. The water in the solution will dissolve the salts, which is why Windex is still an effective cleaner. You don't need it though, hot water is effectively free, Windex is not. The only problems you might have is if you have pretty terrible water and it will leave behind ugly and possibly damaging scale as it dries. And of course you need to finish the cleaning with a water displacing lubricant.

(I think the whole idea of Windex is that it would reduce any unburnt powder/primer? Not sure why that would be a concern though, as that stuff should come out with the water rinse too. I never understood how Windex/ammonia got to be a thing when it comes to corrosive ammo.)

If it's an AK, throw it in the creek and leave it there forever. Pretty simple, really.

I wonder how some CLR might work on it?

Ammonia helps clean copper since you were wondering.

Good to know. I never had a problem with copper fouling, but I also don't shoot the cheapest junk I can find. I like cheap, but I want at least a modicum of quality.
