I spray break free in the barrel and let it sit. I use break free on the other internals while the barrel soaks. Then I dip a nylon bristle brush in Hoppes #9 and run it through the barrel. I use a boresnake to finish up after I'm done.
Also I shoot a lot of lead. Sometimes even pure lead. If I have lead fouling I will take a 38 brush wrapped in a piece of choreboy. I run that through my 45 barrel a few times. It will remove all the lead in just a few seconds. I bought a Colt 1917 that had so much lead build up I thought the rifleing was gone. Did the choreboy trick. In less than 5 minutes the bore looked brand new.

Not long ago I had an issue with Hoppe's #9 in my S&W 686. I cleaned the pistol after some shooting, reloaded it and put it back in the gunsafe. A week later I got it out and went to jack the rounds out and they wouldn't budge! Panic starts to set in. So I gently knock the ejector rod against a wooden block and slowly the rounds backed out covered in vertigris! evidently there was a little solvent still in the chambers which reacted with the brass cases. Cylinder is OK after scrubbing out the vertigris. Now I have switched from Hoppes back to Shooters Choice (which I had used for years) and I never leave brass case ammo in the cylinder, switched to nickle plated.

I guess I'm just too old school for this discussion. Windex? WD-40? WATER??? None of these have ever touched my guns. I only use purpose based chemical products to clean my firearms and nothing that can make them worse than when I started. Hoppe's #9 to break up powder fouling in barrel, action, trigger, canned air to blow out any place I can't reach with brass brush or jig, Break Free CLP for areas that don't need heavy lubrication and Rem-oil for bore, breach, action and anything that is going to be under heavy use. Guns get cleaned after use or once a month without use or packed in Cosmoline and wrapped in wax paper and crated for long-term storage.
