I have been making oil for several years now mostly working with tric's now from dry ice extraction . Im looking to dive back into washing so to speak . I have come across multiple sources that talk about refluxing and it being a superior product and was wondering if anyone else was using this method . I am also looking to switch to a non polar solvent and doing several washes with ethyl alcohol and water . Three solvents have caught my eye Hexane , petroleum ether and chloroform ...the later two have superior extraction . All thoughts and opinions welcome .
