I rarely see anyone mention 100% iso & I'm not sure why. i used to get it at industrial supply places, not sure what all of it's uses are but if anyone gives you a funny look when you ask for it you need it for cleaning aluminum or stainless prior to welding.
This exists? I've never seen nor heard of it, so I wouldn't know where to buy it.
As it is now I just pickup a 5 gallon bucket of 99%. I use it for cleaning shit off though not making oil.
I like Acetone. It has a pungent sweet aroma until you rid of it residually, so it's not too tough to tell when you're down below the taste threshold. Acetone is a natural byproduct in digestion/metabolism, so tiny Residual exposures scare me as much as ethanol in my dabs does. I still go for full removal, but find acetone is much easier to remove without as much heat as alcohol.
I winterized about 90g in acetone and after it was filtered I let it sit in a pyrex to evap.
The acetone passively evaporated in about 4 hours.
When I put it in the oven I got a nice big muffin and was able to purge all the acetone out in less than a day IIRC.
