The biggest key in cleaning airbrushes is to use the appropriate solution for the job. Cleaning up after the use of hybrid makeup requires rubbing alcohol; we prefer the 91% variety. Water-based makeup is easily removed with water. NEVER mix the two unless you're fond of clearing out gummed-up airbrushes! If that should happen by mistake, toss the airbrushes into a sonic cleaner or soak them in Createx-RESTORE. Follow the manufacturer's directions for use. If all else fails, tear the airbrushes down and clean them thoroughly.
