What chemical can I use to remove the ink staining from my screen. I've tried a de-hazer....applied on a dry screen let it sit for 10 mins and used a pressure washer, not luck. There is also some areas with small clear spots that look to be blocking the screen. Not much but I would like to get it off.
Kiwo Pregun paste would eat a screen if left on too long, same with a few others I have used over the years.
autotype made a two part system (I think it was them) where you brush on the paste, then leave it over night - then add a liquid the next day, and bang - it worked.
I have tried 'enviro' stuff that didn't make a bit of difference on ghosts, no matter how long it was on. I've seen and heard (but never used) the franmar products do work.
So, whatever haze remover you use, read the instructions and follow them.
I use this stuff called Imagemate 750. The longer it sits, the more it takes off. But if you leave it too long, it pops the screen. I used to dehaze after every print (especially with solvent based inks) now I do it only when the ghosts get really bad.
I find cleaning the screen/ink right after printing helps keep the ghost to a minimum.
Not a big fan of 80 grit or magic eraser - anything that physically abrades the fine threads will eventually break them, or start picking up more ink/stain, or both.
