First off wep45, DO NOT use stainless brushes on your weapon! Bronze brushes will remove anything that needs removing. If any cleaning is done on the outside, nylon will work beautifully. An example: if a .357 revolver is used to shoot .38 spl. ammo, cylinder will have debris left in the charge holes, use a ,40 cal bronze brush in a cordless drill, dunked in Hoppe's #9, run this through the cylinder holes, in a couple of minutes all debris will be removed, then clean with standard clean rod. Don't use drill on barrel bore! I have used a product called "Renaissance Wax" to protect my revolvers, a light coat applied and then wiped off will take care of any questions regarding finger prints, etc., the NRA museum, England Edged Weapons Museum uses this product also, good product. I bought mine off Midway USA website. Hope this helps, good luck! Alcohol "can" be used, no need though.
