How to remove copper deposits from muzzle brake/suppressor mount?

[1KPerDay]

Been wiping it with hoppe's no. 9 but doesn’t seem to be having much effect. Tried a bronze brush, no effect.

crusty carbon/copper deposits.

Hoppes is weak sauce for copper, and mildly effective for carbon.

I'd qtip Copper Killer or Sweet's 7.62 onto the brake for the copper. Heavy carbon wants better than Hoppes for sure.

The Black Label Hoppe's is better for copper, but I second the suggestion for Sweet's 7.62 Solvent. You could pull the brake and soak it, or stand the upper in a tumbler filled as high as the brake with solvent.

so last time I had to do this, I soaked the muzzle brake in hoppes #9 (that's what I had) for a week.

Still was a bear to get clean.

I like to use Barnes CR-10.

Another vote for CR-10. Best copper remover I have used.

CR-10 is good stuff, too. Used it in the shop I worked in.

Motor Oil is good shiz mate.

Ultrasonic cleaner and some degreaser for the carbon.

Coat freely with sweets for the copper.

I soak my brakes in foaming bore cleaner....that seems to work

I have been using stainless steel brush and what ever oil I happen to be standing closest to.

Barnes CR-10 or KG12, they both smell real, real nice!!

I take my Stanley knife and just scrape it off. Works very well and is very quick.

That was some serious sarcasm The KG12 is less nasty I find.
