Corrosive ammo cleaning

[Twinson]

Is there a commercial bore cleaner that removes corossive ammo salts? Does Sweets 762 remove corrosive ammo? Thank you, James.

Windex with ammonia.

The "corrosive" part of corrosive ammo isn't! The primer compound (a miniscule quantity BTW....less than 0.25 g/primer) leaves table salt's (NaCl) lighter cousin, potassium chloride (KCl) in the bore. In and of itself....it isn't "corrosive", but it IS highly hydrophyllic, meaning that it'll draw water from ANYWHERE...the air, your body, and form an electrolytic solution that IS corrosive. That hydrophyllic nature is also how you clean it.....it LOVES water, so you make sure it gets access to some! Old USGI bore-cleaner designed for corrosive primers was kinda "milky" and rusted it's way out of the metal containers it was stored in because it was an emulsion that contained a hefty percentage of water...old (and maybe new....I haven't checked the MSDS in a while) Hoppes had enough water in it to clear KCl out of a bore....I doubt Sweets has a drop of water! Plain old water is the key!

Red's suggestion of a little Windex is completely valid (it's mainly water with a little surfactant!). Failing that...the "cheaper alternative", is cheap automotive "blue-juice" windshield washer fluid. If you don't want to travel the "high-tech" road, then a patch or two of plain old tap-water (hot)....maybe with a TOUCH of dish-soap as a surfactant to make sure the water gets into all the nooks and crannies, and then dry-patching will do the trick!

i don't mind shooting corrosive ammo in a bolt rifle but i don't think its a good idea in a semi auto if it can be avoided. (a complete dissassembly is mandatory). i find its always best to inspect a rifle a few days after cleaning. i'm always surprised at how dirty a 'clean' bore can become in a few days as is the case with gas systems.

Regulations used to specify cleaning for 3 days to get rid of this residue from all parts of the rifle subject to powder fouling.

Sweets 7.62 has ammonia in it and will do the job, its still the best barrel cleaner as far as I`m concerned

Unfortunately, KCl isn't soluble in "ammonia"! Ammonia is used to remove copper-guilding metal fouling....it has NOTHING to remove chlorate residue based on the MSDS of the product.

that reminds me of a cool licence plate i saw the other day,

"lb nacl"

i figger about 10% of the folks here will get it.
nyuck, nyuck

You sure it wasn't "lb sio2"

Ammonia does nothing to clean out the salts. Plain, hot, tap water will do.
