I don't add any salt. I just literally make an aqueous solution with a pH of 12 or higher so the DMT becomes more soluble in the naptha then in the water. I let it sit and you barely need to do anything to it just stir gently ever couple of hours for a day and you only need 1 pull. It's super simple. People use viniger or other acids to speed up the extraction by breaking the barriers of the cellular walls on the MHRB or whatever they're doing. Unless, their doing an AB extraction. You'd acidify your solution, use your non polar solvent to full any fats and unwanted material out of your solution, separate the solvent from solution, get rid of solvent. Then bring your pH up to 12 (for MHRB) and re add your non polar solvent. This time since your solution is basified, the solvent is gonna pull out the DMT because it's now in its freebase form andd soluble in non polar solvent and not in the solution
