How to clean airbrush with dried on acrylic matt varnish?

What airbrush do you have? I would not submerge the airbrush as the O ring in the air valve can be damaged from chemicals. I would soak the front half of the airbrush in Super Clean degreaser overnight and go from there.

Carburetor cleaner from the automotive section is my favorite airbrush cleaner. It will remove ANYTHING. I have an Iwata and a Badger and there have been not adverse effects.

Hi,

thanks for that I'll give it a go.

Ooh, did I spell it finners ! Thicko, should be thinners :-) I'm going senile

Ted.

I would say celly thinners, although depending on your airbrush (rather it's seal material) soaking might be unwise.

I would put some celly thinners in, flush this through the brush, let it stand for a few minutes, flush the remainder out & then remove the needle & check that there isn't any build up on it around where it travels through the needle seal - if there is a few wipes with thinner should remove it.
