DMTripper,
the following gem is from Benzyme, in
this thread:
"there is no specificity as far as what hexane or heptane will pull, both will pull the same compounds.
VM&P contains both, as well as octane and nonane. may as well save the Bestine for re-x
better yet, get some methylene chloride. its toxicity is often exaggerated, but its ability to pull alks trumps all other solvents (except the more toxic chloroform)."
I believe you were part of that conversation...
