I inherited some old screens from a friend and I can't remove the emulsion from them.
I don't know what kind of emulsion was used (and neither does she as she got them from someone else).
I have tried Ulano #5 (Sodium Meta Periodate) gel and Diazo Emulsion remover. and scrubbed like hell (I don't have a power washer). The emulsion is dark red.
Any advice on getting this stuff out?
thanks,
dirk

Be kinda hard to adhere rubylith (God, I haven't use that word in awhile!)
to mesh.
Is it possible they are old fashioned lacquer film?
Get some lacquer thinner and rub it in a corner to see if it dissolves.
If it does throw them away! Trying to remove it completely is more
of a pain than it's worth.
If that doesn't work try a little regular household bleach.
Paint it on both sides with a cheap paintbrush
and let it sit for a couple of minutes.
Rinse with low pressure water and then power wash as usual.
Don't let the bleach spray back on you.
It may make more sense to just re-mesh the darn things.

Thanks!
the bleach worked, although it took a lot of scrubbing and re-applying (I don't have a power washer).

They could be hardened screens. I used A&B hardener on a long run waterbased job I had and I had to cut the mesh out and re-strecth because that stuff was never coming off. The best advise is, get a pressure washer! Its unbeatable in reclaiming. Also, if you have a tank big enough to submerge a screen in you could try dissolving some salt in water and soaking the screens in it for a day to soften the emulsion. You can also soften emulsion with degreaser before putting on the emulsion remover.
