PEG is easy just use water.
I salvaged about 300ml of crude by flushing it with hot water in a sep. Funnel i had a heater wrap that I wrapped around the sep funnel to keep the crude inna flowable form. I poured in my hot water, mixed then separated the washed crude off the bottom. During SPD there was about 20ml of water/ PG that fractioned off with the terpenes. Total yield of distillate on that washed crude was like 180g from 250g crude.
