There's only one way to make BHO that's why its called BHO.
I wouldn't recommend using denatured alcohol, it often contains denaturants with high boiling points, to stop people from trying to redistill it. Pure ISO or acetone would be a better option than denatured ethanol, unless you are certain that the only denaturant added is methanol. SLX denatured alcohol contains the denaturant methyl isobutyl ketone, which has a boiling point of 117-118 °C. If using polar solvents on such a large amount, then you really want to strain it through a regular sieve or mesh first, before filtering through papers. Otherwise too many impurities would leach into the solvent by the time that you've filtered that much through papers.
WHAT SECTION of the depot, and its jsut called denatured alcohol slx? thanks
Acetone is baad stuff,
