Air Brush Inks Cleaning Airbrush - When you are finished using your double action airbrush for the day or you have long waiting periods between use, to clean your airbrush spray Reel Developer or 99% Isopropyl Alcohol into an airbrush capture trap. Airbrush disassembly is not necessary. Once you have determined that the airbrush is clean, spray a drop or two of mineral oil through and let sit until next use. The less you disassemble your airbrush for cleaning the less wear and tear on the airbrush. When you are ready to use your airbrush again simply spay a small amount of Reel Developer or 99% Isopropyl Alcohol through to clean out oil residue before spraying ink.
