If someone is absolutely determined to purify a substance (which we do not advise), the scientific literature points to from hot isopropyl alcohol, not acetone washing. However, that requires even more skill, hotter solvents, and longer times.
Acetone-free removers typically use ethyl acetate or glycol. These solvents do not have the same selective solubility as acetone and may either dissolve the meth entirely or fail to remove the specific manufacturing byproducts (like lithium or "pill gunk") you are trying to eliminate. The Result: washing meth with acetone free
In chemistry, "washing" methamphetamine involves removing impurities left behind during its manufacture. Acetone is typically the standard solvent for this process because methamphetamine crystals are in it, meaning the drug stays solid while the impurities (like excess precursors or "cuts") dissolve away. If someone is absolutely determined to purify a
Commercial "dry acetone" or "anhydrous acetone" can be purchased from chemical supply houses, but these are often flagged by law enforcement. These solvents do not have the same selective
