1) Wet 3 to 4 Bore Tech X Count patches with C4 Carbon Remover and individually push through bore to remove loose fouling. Only push patches through the bore in ONE direction.

2) Next, make 10 to 15 passes with a tight fitting Bore Tech brush saturated with C4 Carbon Remover.

3) Then repeat Step 1 and let C4 Carbon Remover soak for 5 to 10 minutes. For badly fouled rifles or parts, extended soak times may be needed.

Hands down the best!!!! 5 of 5 stars

My 1911 had very bad carbon fouling. Nothing I could find would touch it. The patches would come out almost completely white. This stuff works, Sure it took 7-8 cleaning runs as per the instructions and about 100 patches. It got the job done and my barrel looks new again. My only regret is not buying the bigger bottle. I figure with regular cleaning after each range trip it should only take 1 cleaning run to have it looking new. Bore tech, thank you I am a customer for life.

I love these products! 5 of 5 stars

Recently I called and spoke to one of your knowledgeable staff describing to them some of the barrel fouling issues I was having. After having purchased a bore-scope earlier this year I was convinced that my .338LM was in need of a barrel replacement. I just wanted to leave this review and say that after using your Cu+2 Copper Remover & C4 Carbon Remover all signs of fouling are completely gone from all rifles. The carbon and copper solvents worked extremely well without offensive odors or harsh chemicals. I love these products! You have another salesman working for you... Thanks!
