Thread: KG 12 copper remover

Hey guys how do you know if all the copper fouling has been removed when using this stuff as the patches dont change colour?

Try one with ammonia?, if it turns blue its still there just dont use a bronze jag.

So they are staying yellow? Usual go black for the first couple if there’s copper.

Yeh staying yellow. I thought they went black if there was carbon????
I used KG 1 carbon remover until the patches came out clean then switched to KG 12

I had trouble with copper last year in the 06 , try gunslick foam it go,s really blue spray down the barrel till it comes out the other end wipe off excess & tape it up leave it for the night barrel down , repeat till copper is gone.

Cheers, will give that a crack....just seems stupid that you have to use another copper remover to verify if this one is working

Cheers @Boaraxa

You should be able to see copper with a good light at the muzzle.

Boretech Eliminator is very good for both Cu and carbon removal. Shows up blue with Cu unlike KG12 which does not. +1 fo using a LED torch for observing residual Cu in the lanz at muzzle

Of all the snake oil I have used, Boretech Eliminator works the best

Cheers guys, checked out the muzzle with a torch and can't see any copper

Do you guys ever use a copper or nylon brush after a shooting sesh or just patches ? If u don’t use a brush very often at what point do you use one ?
I’m pretty good these days at cleaning after use but still if I’m developing a load or doing a drop chart crud has a way of building up I’m thinking a brush could prevent build up ?

Careful using ammonia based cleaners with stainless barrels, not a good mix. You will see that your Boretech products & others generally advertise ammonia free for that reason.

Nylon brush when required but patches only most of the time.

Old school hoppes 9 removes copper to if you leave it in your barrel for a few days, quite a bit comes out.
