For those who use acrylic paints constantly here is a homemade recipe to obtain lots of airbrush cleaner for a few coins. With this cleaner you will keep your airbrush soft untill you need it again. I use it after the main hard cleaning with alcohol or windex, depending on the paint I have used, this recipe eliminate the rests of the solvent you have used before and prevent obstructions.
Just mix in equal proportions water, 96º alcohol and windex.
A better quality cleaner if you use distilled water, isopropilic alcohol and a good window cleaner.
One tip, block the mouth of the airbrush so the air will get out through the paint capsule, cleaning the nozzle the reverse way.
