Ive used hoppies #9 for a while. I get Blue Patches, with it. Just let it sit. I have no need for harsher chemicals. That's just my preference! Im not shooting hundreds of rounds per month, either!
To the O.P., try using different ammo and see how it shoots. If it's shooting fine, I don't see anything to worry about. A little fouling never hurt anyone!

Hello all, I'm here to engage in polite and respectful conversation. Just left a very nasty forum where they like to TALK about GLOCK.
