I don't think I have ever cleaned my airbrush once in the last 20 years of using it. Granted it takes a very long time to get the paint nice and even. I probably have to use more paint than I should with this particular airbrush, but it is what it is.
I guess I could run some soapy water through it once in a while, but I really don't see the need for it as it has never clogged up and the air pressure has never been an issue, sometimes it low or high pressure, but that is definitely on me. I am still working out a way to maintain consistency throughout my two to four hour paint sessions depending how much surface area I have to paint.
I don't even see a brand listed on my airbrush, I picked it up so long ago that I don't even recall what the label was on the box, but I think it came with 25 of them in the box. Maybe I'm using the wrong one for the job or just haven't mastered the use of the airbrush.
Maybe someone can give me a few pointers and let me know what I'm doing wrong. Here is a picture of me using it years ago.
