Just cleaned my M9 the other night. The following night when I checked it before bed I noticed distinct discolored/light areas on the metal slide. Has anybody else experienced this? I used outters cleaner and thought I wipped it down pretty good afterward. Any suggestions for future maintenance.
I had the same issue with my S40 after using Gunscrubber. It left au unsightly discoloration on the slide. I used some Break Free on it afterwards and a silicone cloth and it took most of it out. The break free powder blaster is a citrus oil based cleaner and is not as harsh as gunscrubber. You may also want to use a little FLITZ polisher on the slide. It can take out some of that discoloration as well.
