I disagree with the above as taking it apart each time is unnecessary.
Here is the cleaning method I have posted here before and I modified it expressly for the 360.
Cleaning the Badger 360 airbrush
I like to spray out the airbrush at higher pressures and use 50 psi myself, but if yours only puts out 20-30 then just use as much pressure as you can.
Dump the excess paint out and wipe the cup with a paper towel or rag.
Rotate the cup into gravity-feed mode and fill the cup about ½-¾ of the way with cleaner and then take an old paintbrush and wipe around inside the cup and down in the bottom of the cup around the needle with it to break loose the paint particles. Just dab it into the needle area in the bottom of the cup and it cleans very well.
I like to use a round paintbrush for this so that it can get down into the opening.
Just make sure the paintbrush is not one of those real cheap ones that the hairs fall out of, as you don’t want the hair getting into the airbrush and possibly causing problems down the road.
After that, spray the cleaner out of the airbrush and repeat that process until you feel it is clean enough inside the opening.
Now rotate the head of the airbrush to siphon-feed mode, put some cleaner in your siphon-feed bottle, and spray that through it for several seconds.
Take a rag and hold it over the end of the airbrush to stop air from coming out of the tip. Push down on the trigger and pull back slowly and you will see bubbles in the bottle as you are back flushing the airbrush. Do this for maybe 5 seconds or so and then spray that cleaner out as it will have a little bit of paint in it from backflushing it. Put some more fresh cleaner in the bottle and spray that out also.
If you feel that the cleaner is coming out clear then you are done.
Some people like to then just spray air through the airbrush for several seconds to dry out the insides, but that is up to you. Sometimes I do it and sometimes I don’t.
Now wipe the inside of the cup out with a rag, as well as your siphon bottle and wipe any paint off the outside of the airbrush. That’s about it.
About every 4 or 5 times of using the airbrush I will take the needle out after cleaning the airbrush and wipe it off with a rag with some thinner on it to get any paint that may have not gotten cleaned quite well enough in previous cleanings.
I also clean the nozzle of the airbrush as well. You can soak it in cleaner for a while and then insert a small brush or end of a pipe cleaner to wipe the inside out.
Be careful not to jam it in there though as you do not want to damage the tip opening. Be gentle with it.
I then apply Badger Needle Juice or Medea Super Lube to the needle to help eliminate tip dry and keep paint from adhering to the needle. I also like a drop on the trigger to make it smoother as well. These two products do not affect paint at all and are safe with enamels, lacquers, acrylics, and urethanes.
Every airbrush expert I know does not recommend disassembly to clean it each time and I agree.
Disassembling the airbrush each time is not necessary and I don’t personally recommend it because the potential of damaging the needle, tip, needle bearing, and other parts increases each time you take it apart. Some people feel it is better to take it apart each time and give it a thorough cleaning, and you have to make that decision yourself.
I hope this is helpful
