I use "Monoject" syringes...you can get them from your dentist. I rotate 3 airbrushes (3 different tip sizes) all the time. I also use Createx 2 oz. bottles with adapters. Remove the bottle, invert the airbrush, spray residual paint into a towel (hanging at my bench into a bucket). Fill the syringe with clean water and simply squirt it into the airbrush as you spray. Squirt until water sprays and overflows clean. The tip of the syringe reaches down inside the airbrush to flush out residual paint quickly. I also have an old "Mean Green" bottle filled with a mixture of 2 parts water and 1 part cleaning solution. An old airbrush bottle cap with nipple, screws on perfectly...you will just need to find a piece of tubing to reach the bottom of the bottle. I use this after 3 or 4 color changes. Place the airbrush on the bottle with the bottle between your legs. Loosen the needle in your airbrush, and gently move the needle in and out, and rotate it with one hand while you spray with the other hand. I will always use the bottle method on a gun when I am finished with it for a while - NOTE: leave the last shot of water/cleaner in the gun during storage. This may sound silly, but it works well for me.
