cleaning exposure unit

Hey guys,
Just picked up a little Lancer exposure unit. Obviously the previous owner had no pride of ownership and didn't care about cleaning his screens properly. The top blanket is covered in dry plastisol ink. Does any one have ideas on how to clean this without replacing the blanket or damaging it?

Not sure how his screens came out, the glass was covered in dry emulsion and ink. Took almost an hour to scrape and clean it all off.

Thanks for any help you guys can throw my way!

Have you tried just a light screen wash on it? Maybe an enviro friendly one. That is my go to for most clean up in the shop.

Thanks Printerk, I thought of that but the blanket is like a wet suit material. Not sure if the screen wash would damage it???? I was thinking of taking off the exposure unit and try to pressure wash it to see if I can at least get most of it off.

I’m thinking more of like a soy based screen wash which would be less harsh. You could always try just a small section. Those blankets are pretty sturdy, although to be honest it’s been a few years since I’ve used one and don’t have one myself at the moment. Power wash seems like a good idea if you can manage to get it off with no problems. Let us know how it works out.

I would not think that power washing would be a good idea. If the blanket has some worn or weak spots, you'll just wind up tearing it.

Gloves, old t-shirt, mineral spirits (paint thinner) and selective use of elbow grease will take care of the problem.

If you don't want to take the time or make the effort, then spread a lightweight black cloth over your screen before closing the vacuum unit.
