How to clean stains in screens?

[Frog]

The absolute strongest of those has to be the Autohaze paste, though the stuff from Ulano is perfectly capable of eating through both mesh and skin as well.
However, these liquids like Liquid Renuit are a completely different animal.

I don't keep the caustic stuff around anymore.  I had an old gallon of it floating around that finally disappeared.  I think we watered it way down and used it as dehaze.  It was too strong at 100%.  We use imagemate 260 now and that works well.

I believe that with more education about proper exposure coupled with the move away from petroleum based solvent cleaners, emulsion based cleaning problems which required these strong caustic cleaners are becoming less and less common.

CCI  GR-70

Use it as a ink degradent and then use it again after removing the emulsion. Your screens will look new again. I had a screen that was 3 years old with a ton of ghosting from old jobs. It looked frosted it was so old (still printed fine) I sprayed on the GR-70 rubbed with a scrub brush just to move it around so everything was covered. I did both sides. Then I let it sit for no more than a min (it will not hurt the mesh no matter how long you leave it on) then I pressure washed it off. The mesh was as good as new. No ghosting or ink stains.  I used to use screen opener to get my white, red and yellow stains out. Now I just use GR-70.

Once again, not from Easiway, but definitely my favorite product for this is Liquid Renuit from CCI
