Airbrush Cleaner: Eliminates rests of colour and lubricates the mechanism of the airbrush without causing damage. For more thorough cleaning, soak valve and nozzle (but not the whole airbrush) for several hours. If used to rinse out paint between exchanges of colors, dilute with 50% water. Avoid inhaling the fumes, and use only in well ventilated rooms. Keep out of reach of children.
