I checked up on the airbrushes (i try to check on them often) yesterday to find that 5 out of 7 have been used and not cleaned enough for the next person to use without having to clean them again.
Anyone who has taken my class (or Rio’s) will know that keeping the airbrushes clean is the #1 focus, and a necessity for good operation,
Be excellent, and if you need a class just ask!
