Home Forums Hunting & Shooting Hunting Rifles The best bore cleaner you ever used?

Windex is a common recommendation for cleaning a barrel shot with corrosive ammo. I've used it on a Mosin-Nagant shot with 60's-era Czech Silvertip and 80's-era Romanian corrosive ammo. It works for that purpose.

As for copper removal, it's not going to do much. Janitorial strength ammonia (9-10%) is supposed to work well for copper removal, but I've never tried it.
