I was just trying reclaim/clean some screens and I can't get the emulsion to come off. I don't have a pressure washer so it usually takes some extra elbow grease, but this time around I can hardly get pin holes to washout.
Does reclaiming chemical expire?
There's a note on the side of the bottle that says "Do not allow to dry or it may permanently set emulsion." Is that true even if I rinse it really well?
I just used the chemical a month ago on the same screens with the same emulsion and it worked. Any help would be greatly appreciated. Thanks!
