"Hi, you've made it this far, and now your airbrush is probably filthy, and you're wondering, "what do I do now"? First off, you just want to kind of take it apart, but try not to take it apart too far until you get a little more advanced. This is my side feed, the cup actually comes off and you can throw it in some rubbing alcohol or some warm water, take a Q-tip, wash it around, wipe it off. You'll take the back off, it just unscrews. And then this little needle chuck right here, you just pull it and you slide your needle out, be very careful because these needles are sharp. And take a piece of paper towel and just wipe it off, is all you really need to do. Once you have it back together, the cup is clean, put it back on the airbrush, fill it up with your cleaning solution, and spray it out a few times, and that's all you really need to do. If you've got a really bad clog and you really need to take the tip apart, on some of these airbrushes like this one and my gravity feed brush, is very, very tiny, and they're very costly to replace."
