Mattv2099 gets domestic with it:
HA surface rust… Glock tenifer laughs in the face of surface rust! Probably would have been better if he would have field stripped it before putting it in the dishwasher. The soap probably also was a bad move / unnecessary.
Not something I’d do, but I imagine as long as your dishwasher water doesn’t get incredibly hot you’d be fine. The one thing that suck though is you’d need to detail strip it to re-lubricate all the internals if you actually care about your gun for sure functioning properly.
