for the ink removal part, all we do is drop the inked screen into a CCI dip tank, no lid - crack the ball valve a little to general air bubbles, leave them for around 5min, pull out and rinse...we can do 5 at a time. no scrubbing, no spraying on chems, just hit with water and go.
Gilly, I don't really know, never had that before. my next investment is a 3rd tank to drop the wb screens in and walk away instead of rinsing.
