If I Decarb under Vacuum, would I avoid Oxidation?

that’s is a waste of 60 hrs imo…

No need to purge crude that’s going to be winterized?

@cyclopath

I’ve gone into ethanol without oven purging since day one. or atleast the first time I winterized, which was many moons ago. open blast into a canning jar in warm water. adding ethanol to drive off the last of the butane. into the freezer.

With a CLS, I used to recover to 15" or so of vac on my receiver then use that vac to pull a measured amount of ethanol in.

I would posit that you’ve also been huffing quite a bit of iso… if you’re recovering your solvent, why not use food grade ethanol?
