Thought I would try one of the foaming bore cleaners that are out there. I have been hearing rave reviews about some of them but my first experience was very disappointing. I just tried the Hoppe's foaming bore cleaner AFTER a thorough cleaning with Hoppe's 9 and JB. I followed directions properly and after 3 applications,nothing could be seen on the patches. Then, the checker....applied Sweets......patches came out green/blue. My question, are all these foaming bore cleaners the same????
