I clean the gun by first filling the cup with Windex, shaking it up and wiping the inside of the cup with a paper towel. I then fill the cup with lacquer thinner, shake it up again, and spray that solution through the gun at a higher pressure (30lb. or so). Sometimes I will repeat the lacquer thinner process and jab the needle feed area with a small brush to loosen up some residue. Spraying one more cup full of lacquer thinner will complete it. Sounds like a lot of work, but it goes quite quickly.
