Favorite methods and products for removal of heavy copper fouling.

My go to for heavier copper fouling is Hoppes Copper Terminator and for real heavy fouling I use Sweets 7.62. I have found both products to work very well.
 
If it is really fouled I will first use JB Bore Cleaner on a copper brush... about 25 strokes using a bore guide... then any of the copper solvents... Sweets many years ago but today usually WipeOut. That produced the quickest method.

I’ve been having good results with Wipeout Tactical Advantage. Non corrosive and is okay to soak overnight. Did a wonderful job on an old Husqvarna 8x57 I have been working on.
