hmmm, i know that if you use 90% alchohol pour a bit in the piece after youve scraped most of it, shake it around for a while then dump it out onto a plate and set fire to it, repeat until your piece/s are clean and then let everything dry you can smoke the resin after youve scraped everything off with the razor from a box cutter, ive been doing it for years and the resins just like if you scraped it
