Wot? Nobody mentioned Hoppes No. 9! What’s up with that? I thought it was the standard, but maybe not.
My grandfathers both used the smokeless variety on their Winchester M1897 12’s after a pheasant shoot. It was recommended/required by the LA County Sheriff Dept. so my Dad brought home bottles of it.
Accordingly, I’ve used the smokeless No. 9 cleaner since childhood. Later I started using their BP variety solvent and think it’s the best. The company has been conflicted over what they call it for marketing purposes. It’s been called No. 9 Super, Black Powder Solvent and Patch Lube and most recently just Black Powder Solvent. If anything works mobetta than that stuff I’d like to know its name. It doesn’t have the murderous petrochemical odor of their smokeless solvent. The smokeless solvent is the only stuff like that which spouse will absolutely and definitively NOT allow in the house and I don’t blame her. That shit smells like a refinery fire - but it’s effective on lead deposits.
I have read where some BP guys completely clean their guns with just olive oil. Seems a little Greta Thunberg spergy style - but whatever. I use hot water, dish soap and Hoppes. Works easily, fast and well.
