What’s the conventional wisdom on using ultrasonic cleaners at home for handguns? Does anyone here use them? Any brand/model recommendations? Do they remove lead and copper from barrels better than a bore brush (let’s assume we’re talking about the same cleaners/solvents for both methods)? I’ve got some full sized semi autos and it’d make things go faster to put the barrels, slides, and recoil spring assemblies in a bath and let the machine do the work.
