I've been using the same Iwata SBS since 2006. In that time it's had one new nozzle and two needles, and is about to get some fresh packing o-rings, and a nice fresh needle/nozzle just for the hell of it.

I reckon it's fine to soak the nozzle in a proprietary cleaning solution, but probably not for more than an hour or so. I finish up with a fine artists sable brush and fresh cleaner, then blow clean water through it and dry thoroughly.

Clean the rest of the airbrush with the same and an aerosol based foaming cleaner, rinsing with fresh water again. Stay away from the air valve - cleaning solutions can damage the packing, the result being poor or 'sticky' air control.

Personally I shy away from the bristle brush cleaning sets, it's very easy to damage the fitted surfaces of the brush with the twisted wire handles. The only thing that should penetrate the body of the brush is the needle.

Most issues are down to clogged nozzles and bent needles. If you encounter problems, have a fresh nozzle/needle to test.

Make it a habit to ensure your brush is clinically clean at the end of each session. The merest dot of lube as per manufacturers recommendations upon re-assembly should be more than enough. and you'll both have a happy and productive relationship!
