Cleaning an Air Art Gun is a messy process of the past...

Lay a baby wipe on the table. Squeeze all of the air out of the gun and place the tip on the baby wipe. Slowly move across the wipe letting the gun suck in the liquid. When the bulb is totally expanded, squeeze all of the liquid back out onto the wipe several times. Do this several times until there is nothing but clear liquid coming out. It's so much easier to throw the stained wipe away than to clean out an entire sink where a gun has been cleaned.
