2. enamel in general, wether it be in a spray can or a bottle, it dries pretty quickly. I reckon that water doesn't do much to enamel, i'd remove it as quickly as possible.
3. it does smell good, you might get a headache, but unless you inhale for a really long time, it won't shorten your life or affect. try to air out that room for an hour or so. The smell lasts quite a bit of time.
if you pressure wash it tomorrow... at least let it soak in water instead of dry in the air
Part of your problem is that you printed with such a fine screen.
We use quite a lot of the enamel clear 59000 series.
Generally it takes 24 hrs to fully cure, but if you print with a super open mesh (say 76) it'll take longer. We never print with finer mesh than 230. Most of the time 195 and 156 mesh. It can be thinned down with paint thinner but Nazdar makes some thinners that work better. Enamel cleans up with paint thinner, lots of it. Try cleaning your screens on top of a glass or metal topped table. This way the solvent is just sitting there activating the ink, not just running down the drain. Then when you think you have it all off swith to a screen cleaner and then water. You didn't hurt yourself by using it. Generally you should work wih good ventilation at all times. Even WB inks require some ventilation. I really like the finish it provides. You get a nice high gloss if you're printing on top of already printed colors. On raw paper it sinks into the fibers and kills the shine.
Use laquer thinner (lots) and a couple of absorbant rags. You should be able to get it all off before you go to washout. Water on solvent ink will just freeze it. there are citrus cleaners that will turn solvent inks to somethng that can be cleaned with water.
A trick that works good for all inks before cleanup and cuts your cleaning time way down....
Tape out before the run so the edges of the squeegee run on tape.
Tape out a spot at the end of your print stroke so the ink can rest there (usually a few tape widths from the gutter in towards the image. Tape a spot at the other end where you start, so the ink puddle can rest ther too.
On your last print, when everything is done, put scrap papaer under the screen, and using the squeegee flood on time really thick - do this by putting no pressure on during the flood. bring all your side ink in to the centre with the squeegee.
Wait about 10 seconds
Pull your last print and end up with your ink puddle on the tape. DON'T FLOOD. The thick flood should have loosened any other ink on the stencil, last pull will scrape it clean, and the side tape will only have a small amount of ink, but on the tape.
Carefully scrape up the loose ink.
Peel the tape.
You will have minimum ink to clean from the screen before reclaiming.
