What I used for corrosive ammo cleanup was water. I would boil water in a tea pot and flush the bore and action. Never had a problem.
The 2 main ingredients are NH3, ammonium hydroxide or ammonia water, and hexoxyethanol. The ammonia water is a base, which is why it has been so commonly recommended for cleaning after using corrosive ammunition, but since the goal is to dissolve salts, enough water will do the job. But of course water + metal introduces another problem, oxidation, so the water has to be removed! Hence boiling hot water - or an ethanol product. Windex has both and while there's still some water left behind the hexoxyethanol with the assumed follow-up of a solvent such as Hoppe's will pretty much get rid of the water.Windex?
Does Windex contain ammonia or vinegar?
Never start with a brass brush, bore should be wet first, preferably with bore cleaner. I wet the brush as well. Be sparing with the bore brush, it can wear the barrel as much as firing FMJ projectiles if you're too aggressive with it.How thoroughly do you clean the bore?
Just patches wet with bore cleaner, or start with brass brush?
