just tried something new.. cleaning

[gudel]

so i'm plagued with copper residue. i have hoppes 9 and hoppes bench rest copper solvent. i used the copper solvent, soak it for 2 days, i still get copper in the bore. so i went to pick up a gallon of cleaner/degreaser (2-butoxyethanol) and a gallon of ammonia with detergent in it.
what i did was prepared a gallon of hot water, half a cup of the degreaser then mix it. field stripped the gun, immerse frame, slide, barrel, camblock and slide lock release. shake it all around and let it soak for couple of minutes. take all parts out, wash it off with hot water, and let dry by putting it in front of a running fan.

for the for barrel, i use the ammonia without dilution and nylon brush. brush the bore a few times, let it sit for couple of minutes. all this took about 5 minutes before all copper are gone. the liquid is slightly bluish, while the original color was yellow. flush with hot water afterwards.

after parts are dried, put some oil by using finger tips for even spreads on all metal parts in frame. 2 drops on each slide rail, and two drops below the hammer. thin film of oil in internal slide section and the external part of slide was wiped with hoppes 9.

some whitish residue on the land part on the barrel, i suspect this is probably lead.

science people would probably get a kick out of this one

I don't even know where to move this thread... since it isn't Autoloading handguns I'm moving it anyway.

You let your barrel soak in copper solvent for 2 days?This is not good for the barrel.

Isn't ammonia bad for barrels?

..." Ammonium salts are hygroscopic (absorb water from humid atmosphere), and the chloride ion is one of the most corrosive species around as far as steel is concerned. This combination will corrode any steel surface, stainless or otherwise. The take home lesson here is, "Don't mix cleaning solvents." ..."

..."If you follow the fad of cleaning every shot for X amount and every 2 shots for X amount and so on the only thing you are accomplishing is
shortening the life of the barrel by the amount of rounds you shot during this process..."

Great cartoon!

some whitish residue on the land part on the barrel, i suspect this is probably lead.

If it's lead, a patch made from Lead-Away cloth will remove it straight away after the cleaning that bore has had. If the lead-away doesn't remove it (what is the yellow stuff anyway?), it just might be "frosted."
