Over the years I’ve tried several products and learned what works and what doesn’t.
Hoppes was the first many years back. Without a borescope one thought it was doing a good job. When I got my 30-378 thats when barrel cleaning became more rigorous. At the time I bought one of those cheap borescope cameras (before Teslong came along) and learned about carbon buildup. That’s when I started the Kroil soak and followed with JB bore paste. It worked but with a lot of work. Then I started using BoreTech Eliminator , great for copper removal. I’ve found that Wipeout and Thoroflush all do the same with copper fouling. Carbon is another subject. They all get some out but not completely. FreeAll works fairly well if applied when the barrel is still warm from shooting and allowed to soak. The ultimate carbon cleaner is CLR. This is for stainless barrels only or you’ll remove the finish.
The worst I’ve tried is BoreTech’s carbon remover , after soaking a barrel overnight it does nothing to remove carbon.
Like to hear other’s opinions.
