Have you tried Yellow Magic? I got some yesterday and it's promising, but I doubt it does a better job than IPA.
But one interesting effect is that you can't "contaminate" the liquid. Instead the excess resin gets trapped in tiny spheres and that can be easily strained out. However after leaving it in there and agitating for 5 minutes, then washing the prints with water, they were still very tacky to the touch and you could see that some resin is left on.
The next thing to try is the ultrasonic. Might help.
Nah, I've stayed with the isopropyl. I do use an ultrasonic with water to hold the beaker with the alcohol bath.
I tried to call around to various chemical supply companies to try to get a hold of some tripopylene glycol methyl ether, which supposedly is supposed to be less hazardous than isopropyl or denatured per this document, but no company will sell it to an end user or a small business that is run out of a residence.
I just hate wasting the isopropyl when it gets loaded down with resin. Curing in UV usually just gives me a gelatinous mess and using a distillation setup seems like a recipe for an explosion.
