Thank you. I shall purchase. I believe the Ruger branded cleaning kit I use has a brass brush.
Nope. It says they're bronze. Still ok or not?
Guessing not since bronze is mostly copper.
The problem with brass brushes is that they are effected by copper-solvents.
Some say that they'll actually deposit copper into the bore, and some say that dipping brass brushes into the solvent-container will contaminate the solvent.
What I say is that while both of those scenarios are feasible, I (and most other folks) have used brass brushes for years with perfectly-good results.
To me, the important thing is to do what Pat said relative to cleaning the bore after you're done scrubbing. That, and don't wet the brush by sticking it into the solvent bottle.
On a related note.... I don't stick anything into a solvent bottle except a clean patch, which in turn, is used to wet the bore prior to scrubbing. Sometimes (depending on how neglected the bore is), I'll wet the bore 3 or 4 times while letting the gun sit for hour or so in between, before I even pick up a brush. Reason is, it's the solvent that actually does most of the work, and it takes time for it to do it's job.
Another thing to be cautious of is that copper solvents almost invariably contain ammonia, which itself will deteriorate not only copper, but if left long enough, will also etch steel. Point being that (again, like Pat said), when you're done cleaning, take some steps to get every bit of the solvent out of the bore that you can get out.
As for the brush itself, you'll find that it'll last longer if you slosh it around in some hot soapy water after you're done with it, rinse it well, and let it dry before storing it away.
Hope something here helped.
