This approach is basically along the lines of what inspires Ibee in his quests.
The pre-cleaning usually entails the use of poly-removing solvents before proceeding with alky extracts.
AWE room temp.
The right combo of precleaning solvents has a huge impact on how clean the resulting pfed is.
Depending on formulation, some further cleaning is required.
Nowadaze it's getting more complicated because some inactives are solvent activated and will travel with the goodz til the end.
This is not good.
Ibee's always had the best successes with yields using roomtemp extractions and some other recent posts hint at heat being a yield reducing factor when basing.
Finding the right solvent combo's are essential to success it seems! This has always been the premise that Ibee operates by and tailors his methods to.
A while back halfkast inspired Ibee to look under a rock by a suggestion that ethyl acetate might have a suitable purpose in extraction somewhere.
Ibee is usually not one to dismiss the ramblings of other bees prior to investigation and whatta ya know....that little fucker was right.
I chastised the poor devil because of his brevity and mostly because he had an annoying habit as spectralshift of disrespecting his elders that have given this board much.
Hope he's still lurking in the corners cause I'm all about burying the hatchet
For the sake of not putting an end to a good thing by spelling it out...I'll say play around with some EA and see if you can formulate some success with it as Ibee did just on the suggestion of it maybe helping.
