Premi Air Foaming Cleaner is a highly recommended end-of-session airbrush cleaner for extra thorough cleaning away of water-based products, such as alkali soluble acyrlics.
You can use the straw to direct the aerosol spray at the airbrush nozzle and front parts of your airbrush, up into where the bottle attaches on a bottom-feed airbrush or down into the cup of a gravity feed airbrush. The cleaner foams up to thoroughly get into all of the parts inside. Then spray through with warm water.
Foaming Cleaner is especially recommended for thorough cleaning out of sticky products, such as tanning solutions.
