TEK - A/B extraction please help

[liquorman333]

Hello all this is my first post so go easy ....

swim has did Lejunks acetone wash with alot of success ...wow what a better world swim had.

swim ususally picks up 4 oz at a time and the last two trips the acetone wash helped some but there is still some ruff stuff there

in clorox test all was normal but red floating on top of both batches...swim has read conflicting reports that is amphetemines.

either way swim would like to start performing the a/b but does not understand which solvents need to be anhydrous and how to get them that way ...i understand how to make acetone anhyrous ...but what about the rest

are they naturally anhyrous if bought from chemical supply store?

swim would appreciate any help.
