Cleaning my Airbrush, problem solved

I use an Aztec airbrush, usually with Tamiya acrylics.
I never seemed to be able to keep it clean and spraying smoothly. I'd flush it when done and follow with cleaner. I tried taking the nozzle apart and leave it soaking in water until the next use. 
No matter what I tried it would quickly clog and my spray would be hard to control.

Yesterday, I had a brain fart. I decided to try an ultrasonic cleaner I use for another hobby. I took apart the nozzle, threw it into warm water, and fired up the ultrasonic cleaner for 30 minutes. 
When done the nozzle was spraying as if it was new.
Now I wonder what took me so long to think of trying this
