First, make sure you have everything you need. Also, make sure you work over a towel or tray in a well-lit area.
• Towel or tray (not pictured)
• One dirty airbrush
• A bundle of round wooden toothpicks
• A bundle of cotton swabs
• An interdental brush
• The head cap wrench
• Cleaning solution
• Parts Guide
Use the appropriate cleaner for your paint. Medea airbrush cleaner is for water-based paints.
Take off the back handle (#19).
Loosen or remove the needle-chucking nut (#18). Remove the needle (#17).
Remove the needle cap (#1) and the nozzle cap (#2). Then remove the head cap (#3) – you may need to use the wrench. Then remove the nozzle (#4), it might be stuck inside the head cap or on the body, or it might just fall out.
Examine the nozzle tip. Make sure it’s a true, perfect circle with no dings, dents, tears or cracks. The red circle shows the part you should be looking at.
Next examine the nozzle from the side and make sure that it doesn’t flare out like a trumpet. If any of the above problems arise replace the nozzle, it cannot be fixed.
Use a toothpick to gently clean out the inside of the nozzle. Pay attention to the walls of the nozzle. It’s not enough that you can see through the nozzle; you have to clean the walls until they are bright and shiny.
Thoroughly clean out the paint passage using an interdental brush or an airbrush cleaning brush.
You can also clean out the bottle receiver with the brush or use a cotton swab.
The nozzle goes on first.
The three caps go on next. Tighten the head cap with the wrench.
Gently insert the needle next and also press down on the trigger at least once. Be careful not to force it. If it catches on something remove the needle and examine the airbrush to make sure everything is correctly assembled. Then reinsert it.
When the needle comes to a stop give it a quarter turn counter clockwise to ensure even wear on both the nozzle and the needle.
Do not push the needle to a hard stop, you might crack or deform the nozzle.
Then attach the needle-chucking nut and finger tighten it.
Next, reattach the handle. Your airbrush should now be clean.
Testing your cleaning job.
Here’s the method in a nutshell. Use something readily available that won’t require a rinse after the test. I normally choose water. (As a side note, the pictures are not showing an attached bottle or airhose.)
Attach the bottle of water where the red arrow points and the air hose to where the blue arrow points.
All these tests should be done while holding down the trigger for air. Just press down for air and make sure you’re not getting water.
Pull the trigger all the way back. You should gets lots of water.
Push the trigger all the way forward and reconfirm no water.
Now pull back just a little and hold the spray up to a mirror and make sure youâ€™re getting a round spray pattern.
