To the chagrin of many clean freaks out there, it must be understood that disassembling and reassembling your airbrush after every painting session will cause more damage than just about anything short of downright dropping it. The wear and tear of taking your airbrush apart between sessions will strip down the threads and result in loss of air-tightness around the head that not even the best beeswax will solve!
It is not necessary to take your airbrush apart to clean it over the short term. Suppress your OCD nature and simply run some water through the airbrush, wipe out the cup, clean off the needle, then park the airbrush with water still inside the gun. As long as the internal parts of the airbrush remain wet, residual paint will not dry and cause problems in the gun.
For those rare instances when it is necessary to disassemble your airbrush, we'll be covering that procedure in an upcoming lesson.
