Never soak or leave your airbrush exposed to Windex for any real length of time. You should not have to take your airbrush apart every night to clean it, it is alright to only do a complete break down and cleaning once a month. Just make sure you do not go any longer than that. When you take it apart to clean soak it in a commercial grade cleaner overnight. Nails should be clean and buffed prior to beginning. Buffing the nails will give for a rougher surface for the paint to cling onto. Prior to actually airbrushing the nails, a base coat should be applied. There are actually two reasons for the base coat. This base coat will help protect the nail from the paint and help the paint to adhere to the nail better.

Depending on which brand of acrylic paint that you go with, you may need to thin it down so that it flows freely through the airbrush.
