From the bottle: Contains ammonia solution, use with undersize bore brush & cotton patch, follow with oil soaked patch, then dry patches.
I have not used this stuff in years, Wipe-out made all other cleaning products except JB bore paste, obsolete in my mind.

Anyone know what happened to the guy in Edmonton that developed the Coppermelt bore cleaner?
I have been using a bottle of it for the last 10 years but it's almost gone.
This stuff eats copper like nothing else.
I have not heard from him in a long time, had some copper melt at the old shop that I still have. Drop by and I'll give you a bottle.
Yeah,..I should drop by...I seem to remember something about a chamber job/stock paint job swap....![]()
Janitorial grade (14%) ammonia works great, and will not harm the bore. Have used it for years.
Copper simply disappears, and the bore is left squeaky clean. So clean you must be sure to oil the bore when you are done, because it will rust if exposed to any moisture, including high humidity. Just a couple of passes with some light oil like Kroil, ATF, or even 3-in-1 will finish it up nicely.
