When my first "Dirty" IPA wash gets too murky, I place the clear plastic container out in the sun. And the whole thing becomes a big rubbery blob. I shake it out onto a piece of paper towel or bit of an old cardboard box and set in the sun for it harden up. There is no IPA to recover, the whole thing becomes a rubbery solid. Once well cured, you can break or slice it up like a block of cheese so the smaller bits can dry out faster. I'll probably bring the blocks of cheese to my recycling center so they can dispose of it safely.
I keep 3 cheap clear plastic "tupperware" containers for cleaning. The first container I use for my first wash. The second is filled with clean(er) IPA for the second rinse. The third is filled with the old dirty first wash IPA. I rotate through the containers - as the final rinse starts getting it dirty, it beomes the first wash. The dirty first wash goes out in the sun for curing. And the emptied one becomes the clean wash container.
Not sure if the same process will work if I switch to Mean Green. It would likely take longer to evaporate than the IPA.
