Grex rep explains why Windex is bad for your AB

Oh … !!
AB = Air Brush.

A new abbreviation on me!

Interesting, but I've never had any problem airbrushing Future through my Paasche airbrush, nor using Windex to clean it afterwards.

Of course, I *never* let Future, nor any other paint or finish, dry in the airbrush. That's just lazy and asking for trouble.

I keep a small bucket of water beside the desk when I airbrush. As soon as I'm done airbrushing Future (or any acrylic), I dunk the airbrush completely and shoot the water through it. Then I fill the cup with Windex and shoot that through it. Then I shoot more clean water, then air, then I dry everything off.

I've never had a problem, and I've been shooting acrylics since the late '70s, and Future since the mid-'80s.

I've never had any problem using Windex for cleaning but then I flush out the airbrush with 99.9% isopropyl alcohol immediately after the Windex. I also use Future for clear coats and ammonia is recommended as a stripper for built-up Future, so the Windex works just fine to clean the brush. Regardless of what you're using, the important thing is to not let whatever's in the airbrush to dry inside it. Perhaps Windex is a problem for Grex airbrushes but it hasn't been a problem for my Aztek and Badger (Krome and Patriot)ABs.

Nor has it ever been a problem for the Iwata's I use. If left in the color cup for a very long time it might remove the plating. Makes me wonder how thin the plating is in a Grex cup.

Tim,

I break mine (Iwata) down completely for cleaning after each session.

Frankly, I can't see how one could clean it without doing that.

You have to be careful removing / re-inserting the needle so as not to scratch the tip but other than that it only makes sense so that you can get to the inside of the nozzle, crown cap, etc.

If your model has rubber O rings be careful that they are not exposed to lacquer thinner as it will eventually dissolve them.

Same here, with my Paasche.

To clarify, my cleaning regimen above is between colors in a single session. At the end of the session, the airbrush gets completely stripped and cleaned. It's amazing how much extra paint comes off.

Damn guys!!! Good info, as I have been looking at and contemplating buying an air brush. This is really good info to have.
