Damn, almost 100 views and I'm still talking to myself. All you die hard BHO junkies afraid to step outta line :)

I don't understand how this would make the oil cleaner?
yes i know iso no good for consumption, i also have used everclear in my younger days like ten years ago it was all goooeeey and i never did it again i should run a batch with all my new knowledge.I haven't done it yet, but probably will give it a shot.
Qwiso uses iso, a petroleum derived product, not for human consumption. Everclear is food grade. I've never used iso for that reason....have used everclear many times on buds and kif, and it makes the most potent extract I've ever tried stateside or in the dam.

thats right, after the everclear has evaporated [you can smell that it's gone] you'll see a watery liquid floating on top of your oil.I set the dish in ice water to harden the oil .i then pour off the water than reheat until all remaining drops are gone. actually i don't do any of this anymore.....BHO ROCKS MY WORLD NOW :mad0233:but the water is definitely going to be the last thing to leave during the drying phase.....
This is precisely the methodology that I use/support (methodology, not method).
To begin I'll say I'm a chem grad student, so these notes all come from that perspective and are not necessarily application-based.
I personally reflux with hexanes to get my crude product, but let's just assume I've used butane and allowed it to evaporate off--leaving me with crude, butane infused, oil.
(This skips the water washing step of my hexanes extraction, which I'll be detailing in a few weeks once I've got my new lab set up).
I'd mix hot ethanol, in your case everclear, with the crude product and stir vigorously (I do this in a sep funnel w/ burping under a fume hood to reduce solvent fumes). This will dissolve the oil, reducing its viscosity and releasing what are called inclusion impurities (impurities trapped in a bubble for oil/crystal structure for solid). The boiling points in this case are a huge help and the rest of your butane should be released if you are stirring well. Evaporate/distill the ethanol off and you're left with butane free oil.
Here is my concern with your method:
Everclear, while being safe to drink, is not necessarily safe to smoke/vaporize. Pyrolysis is not one of the tests everclear must undergo to get FDA approval (at least no insomuch as we're worried about the effects of someone repeatedly smoking it, tests may have been done to ensure it doesn't create some chemical-weapon grade gas :P ).
After an hour a vigorous searching, I can't seem to find what binders/additives are in everclear--despite knowing that they exist. These binders are the main area of concern for several reasons:
--They may participate in side reactions with crude oil products
--They may pyrolyze to dangerous substances
--They may yield pyrolysis products which react with other vaporized/pyrolyzed crude oil products.
--They may form azeotropes with various crude oil products either preventing them from being evaporated off, in the opposite direction they may lower yield.
These are a few concerns, and there are even more for one simple reason: We don't know what the hell exactly is in that stuff. All we know is that its' been deemed safe to drink. However, when doing chemistry, you MUST know what's going in to know what will come out.
My recommendation is that you use something called food grade ethanol. This can be had from any number of chemical suppliers (local is best as shipping is a pain). At the very worst you should do some careful distillation of everclear and try to determine its purity/see if the binders/adulterants can be removed.
You may, in your effort to keep it all-natural, be doing more harm than good. The unfortunate truth is that we just don't know.
