The Guru’s Tips

  • Use the right cleaning solution for your paint.

    Like generally disolves like.  Basically if you’re using a water based paint water should work (not always though) alcohol for alcohol-based paints, etc.  WHen in doubt most manufacturer’s have a cleaning solution for their paint.

  • Stay away from ammonia.

    Though this is less of a problem because the Eclipse Gx airbrushes have a die cast aluminum body it’s still a good idea to avoid cleaning solutions with ammonia.

  • You’ll get faster the more you clean.

    It might take you three or four minutes the first time you go through these instructions.  But don’t worry.  You’ll get it down to 30-45 seconds.  It’s more important to be torough than fast, but speed will happen.

  • If you’re having problems this is actually your second, no-brainer, fix

    It’s like being told to reboot your computer when you don’t know what’s going on.

    The first fix is the Color Change Rinse for an Eclipse Gx airbrush.

    The third fix is a Deep Cleaning for an Eclipse Gx airbrush.
