In hot humid weather I have had problems with rust in the gas systems of mod-58, 1100, and 11-87. I believe they suck in moisture in the air when they cool after each shot, to the point that rust has formed before I got home and could clean them. So I clean mine after shooting either the same day or the next day. I will say that the problem has been greatly reduced
since I started using breakfree.
The bore has not been a problem, so one needs to field strip the gun and wipe the gas ring and piston, mag tube, and barrel sleeve. The rest needs cleaning on an as needed basis.
