We’ve found HRG² 2400 Haze Remover that is biodegradable and environmentally-sensitive. It’s available in a liquid form and removes imbedded U.V., conventional and plastisol inks that remain on the screen following emulsion removal (haze/ghost images). It effectively lifts the haze and imbedded ink from the mesh, then emulsifies and dissolves the ink resins, binders, pigments, plasticizers, etc. The solution suspends resins so reattachment to the mesh surface is prohibited allowing for water-rinse removal. And it is an incomparable degreaser!
