What is more controversial? Gun control? Best deer rifle? Remington pump shotgun vs Mossberg pump shotgun? Ruger vs Smith & Wesson? Best conceal carry gun? Best gun for hiking in bear country? Best gun for home defense?......etc etc. The answer is none of the above. The most controversial subject in regards to firearms is how to clean the dang things. I have read countless posts on gun cleaning and virtually every cleaner, lubricant, type of rod and method is hailed by some and cursed by others. How can one guy successfully clean his guns for 50 years using a 3-piece aluminum rod and WD-40, while another completely removes the rifling from his new gun the first time he tries it? I guess some people are just more talented than others.
