I'm a new SIG Sauer P226 owner and I have probably put around 400-500 rounds through my 226. My purpose for having this gun is target shooting at the range. It's my only gun though so I could also use it for home defense should I need to. However, it's primarily for the range. I've read online and watched YouTube videos on cleaning the gun and just general gun cleaning. Many people clean theirs every time they go to the range, some every month, some after so many rounds, etc... While I'd be more inclined to keep mine super clean if I was using this weapon for carry, I still don't want it to be a mess even though I'm not. My issue is, I don't know what's considered "dirty". My gun is two-tone so the slide is easier to tell since it is silver/stainless steel color. The black areas just look black to me. The whole gun looks wet and greasy but it's supposed to be lubricated so I'd assume that's fine. I've found a bit of buildup and some dark streaks but again, I can't tell if that is just dirt or the gun grease. I don't want to remove the gun oil/grease prematurely or clean off the good stuff. Should I just wait until it looks dirty to me and then give it a good scrubbing and re-greasing or should I be cleaning it even when it looks fine? As a side note, can I damage the gun in any way with cleaners? I know that I should not use a stainless steel brush because it could scratch up the gun, but is there anything else I should avoid? I figure I won't use solvent unless it's really needed but could I hurt the gun by cleaning it dry with boresnakes and stuff? Thanks.
