Airbrush Wash Needle
If you are using acrylic paints you will know that they can set as hard as stone!
We would strongly recommend the use of an Airbrush Wash Needle / Nozzle Reamer tool which is inexpensive and will precisely remove dried on paint from the inside wall of your airbrush nozzle.
It has a tapered blade incorporating a flat side,which, when inserted into the nozzle and turned, will carefully shave off dried on paint.
(Fits all nozzle sizes).
This little tool can return your nozzle to prime working performance and will save you many pounds as you won't have to keep buying new nozzles.
