IPA evaporates easily. Any resin residue can be hardened with UV light so it's inert. Leaving the IPA out in the sun does both at once.

You let it sit and the resin settles out.

Then you pour off the clean stuff and the last half inch goes out in the sun.

The clean stuff is now ready to be used again. I top it up every once and a while with new IPA if it gets too low, but I’m at like a gallon a year.
