Cleaning Fatty Solvent

[neuro_rocket]

SWIM has some NP (Naptha) with all the spice salted out, and with a lot of fat in it (there's quite a bit of yellow discoloration).
Is there anyway to pull the fat out of the NP so it can be reused indefinitely?

Maybe washing with a lot of basic or acidic water would work?

I believe activated charcoal might work but it may not be cost effective.
