: Wash all non-porous surfaces (ceilings, walls, floors) and rinse thoroughly with clean water. washing meth with acetone free
Quickly pour the mixture through a coffee filter or a vacuum filtration setup. The purified meth crystals will remain on the filter; the acetone (now containing the dissolved impurities) passes through. Quickly pour the mixture through a coffee filter
Exposure to high concentrations of solvent vapors can cause respiratory distress, dizziness, and neurological damage. This is a dangerous myth
This is a dangerous myth. Fentanyl HCl has different solubility characteristics; it is partially soluble in acetone, but not fully. Some fentanyl will remain. Acetone washing does not make unknown street meth safe. The only way to test for fentanyl is with a test strip.
Standard commercial acetone (from hardware or beauty supply stores) is highly hygroscopic, meaning it readily absorbs moisture from the air. Even a freshly opened bottle often contains detectable levels of water. When this "wet" acetone is used, the water within it will dissolve a portion of the methamphetamine instead of leaving it as a solid to be filtered out, resulting in significant product loss and a lower final yield.
