When I spray acrylics, I clean up with shooting 409, then water. Remembering to backwash the flow, to loosen anything inside.
For final cleanup, I break down the airbrush and soak parts in 409, rinse them in water,then rubbing alchahol, dry them and rub machine oil on the parts, before reassembly. The oil helps keep the mechanism operating smoothly, and the coating protects it from water mineral buildups.
I love 409, the product's ammonia, will break down even year old acrylic.
Don't forget, Q-tips are your friend, when it comes to airbrush cleaning.
