Will GI bore cleaner work (remove salts/acids) after shooting corrosive ammo? Thanks -

That I don't know, but I do know that it doesn't remove copper very well.

Hot soapy water will remove the corrosive residue. A major reason it is corrosive is because it readily absorbs water. (another is the chemistry of the stuff) The hot soapy water quickly dissolves the crud and flushes it out of the gun. The heat from the water heats up the metal. If you wipe out the barrel with a couple of dry patches, the heat will quickly dry out any remaining moisture.

If you like, you can swab the bore afterwards with normal bore cleaners or a copper solvent.

Hot water has been used for centuries to clean up after black powder, and it workes very well for ammunition or percussion caps that used highly corrosive perchlorate priming compound.

I have been cleaning a pair of Remington 1858 reproductions for six months using hot soapy water, followed by lubrication with Ballistol (oil) and they show no sign of corrosion.

Windex with Ammonia will neutralize the salts from the primers. Spray liberally on the bolt face and chamber immediately after shooting and then a regular cleaning once you get the rifle home.

Water will dissolve the salts. Windex works because it is water based. I stick the hose nozzle in the breech end and blast the bore with water for a few minuets, then clean as you would clean regular ammo. Clean the bolt face off with water too.

In a pinch, you can urinate down the barrel....that was derigeur at times in olden days...

A quick extra 2c here. Indeed ... the residue from corrosive ammo is water soluble only. Mostly chlorates it is hygroscopic .. badly so.

A great BP muzzle loader cleaner can be use to advantage here .. I find it very good and use it cold ... no probs.

3 pts Rubbing (isopropyl) alcohol
3 pts 3% peroxide
2 pts Murphy's oil soap.

Mix and store away from light in a yellow or brown jug. I made a whole gallon . and still only part ways thru first pint! I'll be dead and gone before i can use the rest! :D

Once the bore has been swabbed with this mix .. use dry patches until it is dry .. then blow down bore with paint hot air gun or similar - hair drier will do ... enough to warm barrel prior to std oil and solvent cleaners.

The stinky old stuff in the green can does, the alox base stuff was designed for corrosive ammo.

You can't go wrong with hot water.

Hot water is your friend, you don't even need soap or other additives.
Run a couple of dry patches through the bore to remove any soft fouling, then pour several pints of hot water into the chamber. Dry the bore, then oil or clean with a commercial bore solvent like Hoppe's. Hoppe's has some water in it and will remove the salt with a through cleaning.

Then scroll down to the "Care and Cleaning" section. Look for the "Cleaning after firing" part. These are the cleaning instructions given to British Soldiers during WWII and earlier. I have seen very few Lee Enfields with bad bores, and of those I have seen, most were the fault of careless modern owners.

The old RBC in the green or tan cans was designed to clean the corrosive salts from the barrels. Hot water works best since it will both dissolve and flush the salts away. A follow up cleaning with solvents should be done immediately afterward.

I think Water is a large component of the old RBC - US Military Bore Cleaner. That's why it cleans corrosive ammo.

As everybody above said - water is the only way to remove corrosive salts and right out of the tap becomes the logical and cheap way to get it - or, as ole buddy Wildalaska says, you can provide your own water based cleaner in a pinch! :uhoh:
