Well, I usually start by taking the tips off, then the nozzle. Then I take the handle piece off, loosen the nut and pull the needle out. I usually set the needle down on the table away from me, so I don't bend it. Next I tighten the lock nut and unscrew that whole assembly and pull it out, followed by the trigger.
For the cleaning, I dip a pipe cleaner in laquer thinner and run it through from back to front, then I do another one just for good measure. I take some qtips and wipe down the tips really well, and the threads on the nozzle. I clean the inside of the nozzle out with an extra fine microbrush, the white one, dipped in laquer thinner. I find these are the perfect size, and work nicely, but one day I'll probably order a set of airbrush cleaning brushes and do away with the pipe cleaners and microbrushes. I also use a fine microbrush, the yellow one, to clean under that small ridge at the bottom of the color cup. I wipe the needle down with laquer thinner on a paper towel, pulling and rotating it very carefully as I don't really want to bend it.
Lastly I put a very very very thin layer of petroleum jelly on my needle. I find that this prevents it sticking. Super lube would probably be better, but I've not gotten around to buying any,and the I haven't had any problems doing it this way.
When you put it back together, put the trigger in, then the lock nut assembly, then the nozzle and tips, then the needle and handly. You always want to put the nozzle in before the needle, so you don't damage the nozzle trying to fit it over the needle. I like to take a paper towel and shine the whole thing up nicely too, because I like the way it looks
Hope that helps. When are you going to post some pics of what you're working on for us?
