ATF straight. Just swab it in, and let it work. A great overnight solvent,
also good as a pre-clean, before you get home.
Janitor's Ammonia-mixed 1 to 2 with water- for lead or copper fouling.
Klean Strip Brush Solvent--straight-cleans normal dirt
Brown Vinegar-Straight-good for fouled bores, corrosive ammo, and very dirty
Dawn, about 1 to 4 with water
Mobil1- for when you're all done. Just a light lube.
I'm just a po' boy, I can't afford all that "9$ an ounce, like it's
your lucky day" crap...
