I quit the iso because of the cost, smell and hassle when buying it. When I'm getting ready to make the hash I get methyl hydrate. It comes in six, one gallon jugs to a box. It is 99.99% pure alcohol.
do you not understand the solvent is chosen due to polarity differences? methanol being more polar than ethanol and near "twice" iso on a classic polarity index. this makes for a dirtier extract. great for winterizing though assuming you take necessary precautions.
if you breath in the equivalent of half a tbsp of your solvent youll go permanently blind.
soooo, yea. much better smell?
lol
obviously doing this repeatedly requires much lower levels
