Iso, and other alcohols for that matter, pull alot of chlorophyll and other less non-polar stuff. Imho, thats what makes it taste bad. Back in the day i used to get oil from a guy who made it with iso, and it was some of the best tasting and smoking/vaping oil i've ever had.
The trick is, very quick washes on frozen bud, with as dry as you can find ice-cold iso. Stick it all in the freezer, and once its frozen, pour iso into your bud jar and swirl it around for 30-45 seconds. Then pour if off through a filter.
After your done pulling and have evaporated your iso, wash it with warm distilled water. It should pull a bit of crap out of the oil if there is any, and heating the oil up should free up any residual iso to either evap or dissolve in the distilled water.
Thats how i make hash oil from my ABV (already been vaped
), and its pretty good stuff. Not butane good, but nice. I've also used heptane to make hash and vac purged the oil to make sure theres no leftover heptane in it. That was good hash, on par with butane imho. And since heptane is totally non-polar you don't have to worry about chlorophyll and other crap.
The difference between good iso hash and bad stuff is almost always the color, if its not green and amber/transparent you did good. If its green/black and not-transparent chances are its going to taste pretty awful.

In a society in which nearly everybody is dominated by somebody else's mind or by a disembodied mind, it becomes increasingly difficult to learn the truth about the activities of governments and corporations, about the quality or value of products, or about the health of one's own place and economy.
In such a society, also, our private economies will depend less upon the private ownership of real, usable property, and more upon property that is institutional and abstract, beyond individual control, such as money, insurance policies, certificates of deposit, stocks, etc. And as our private economies become more abstract, the mutual, free helps and pleasures of family and community life will be supplanted by a kind of displaced citizenship and by commerce with impersonal and self-interested suppliers...
The great enemy of freedom is the alignment of political power with wealth. This alignment destroys the commonwealth - that is, the natural wealth of localities and the local economies of household, neighborhood, and community - and so destroys democracy, of which the commonwealth is the foundation and practical means.โ - Wendell Berry
