I'm not smart just OCD about cleaning.
No reason to use sweet's or the oil lung burners anymore.
Bore Tech general cleaner is awesome, get's a little messy but when I have a stubborn ugly mess of a bore, It's the stuff.
Wipe-out or the other foamy stuff is AWESOME and easy for light fouler's or daily post shooting sessions. My go to.
Hoppe's makes a couple spray thngs, one is non-toxic and it's pretty darn good, not aggressive but again for light fouling weapons, like my Bartlein's, good stuff.
KG-12 copper remover. When it absolutely, positively, has to be removed in 5 swipes. I've never seen anythingt like it. Have 5 or 6 heavy copper fouler's, and 5-10 swipes of a patch wrapped around an aluminum nylon brush and it' like a magic freaking wand. If you can find it, by two. The carbon stuff works good, all their stuff does, it's just a process and I'd rather squirt foam, wait 10 minutes, scrub and rinse.
I gave away a big box of cleaners to my range after I tried EVERYTHING. In your shop you only need wipe out, bore tech all-purpose or whatever, and KG-12 for your copper stripper. Cleaning will be fun again. C
Edit: Almost every bore I clean end's with a few swipes of KG copper cleaner. It makes me feel good.
