Maintaining a modelgun after firing it is fairly easy, just remember to have oil, hot water, Q-tips,baking soda and some clean dry towels available after finishing shooting the modelgun(s) for the day.The modelguns have to be cleaned as soon as you are done firing them if you want them to remain in good condition.
The trouble with leaving the modelgun(s) un-cleaned, is that the caps filler (phosphorus) is highly corrosive and it rusts the steel and it will eventually, corrode the zinc parts too.
The gasses created by burning phosphorus in the caps gets into the modelguns internal parts so, neutralizing the corrosive phosphorus coating on the detonator and other parts needs to be washed off as soon as possible before the steel parts rust and the zinc and brass parts corrode.
I usually dissasemble and wash the parts the crossive gasses settle on, with a hot water,vinegar and baking soda(sodium bicarbonate) mix.
The baking soda will foam-up when it is poured into the vinegar/hot water so, make sure that the mixture is in a tall container..
This mixture removes the phosphorus residue and leaves a clean surface. I then dry the parts with a hair dryer after rinsing off the parts with hot clear water.
After cleaning,rinsing and drying the steel,zinc and brass parts, the steel parts should be coated with a light flim of oil to insure that they don't corrode.
The mixture works great on the cartridges too...
