I'm doing a ab extraction using naptha/xylene on kratom. What does he mean in this thread "cleaned up with a drop or 2 or acetone"? https://www.dmt-nexus.me...spx?g=posts&m=188507
Does that mean just mix the end product with a bit of acetone and filter and re-evaporate?

Also how long do I wait to scrape the stuff up once the liquid is gone? Should a wait a few days or is it okay to as long as you can no longer smell a solvent? The last extraction I did i washed the end product with acetone but didn't filter then re-evaporated. I think i may of scraped the stuff up too soon, 30 mins after I ate it I burped and it tasted like solvent. stupid me I know.

So any tips on how to purify products and safely would be nice. I hear evapping d-limo leaves a residue, is there any way to get around this? I'd like to stop using toxic solvents but don't want a messy goop of resinous substance.

Thanks for your time!

edit:

Another question, say I do an ethanol extraction and I got a big goop of kratom resin, what's the best way to clean this up? I'd like it to end in freebase form.
