Airbrush Tip - Flush it often

 
The key to cleaning your airbrush, and keeping it clean, is much simpler than methods necessitating airbrush dis-assembly. The key is to avoid paint (or other media) from ever setting up in the airbrush. This is done by simply and frequently shooting cleaner through your airbrush — so frequently that paint/media never has time to set up in the airbrush. When color supply is exhausted, before adding color—shoot cleaner through your airbrush. When changing colors, before adding or attaching the new color jar—shoot cleaner through your airbrush. When setting your airbrush down to do something else, remember paint dries as fast sitting in your airbrush as it does on the item you are painting, before setting it down—shoot cleaner through your airbrush. You cannot shoot cleaner through your airbrush too frequently. At any reasonable time or opportunity, ask yourself “should I shoot cleaner through my airbrush?”. The answer is always YES!
