Naptha is no where to be seen in the areas I frequent.I was curious- Would Bestine work for a defat.. and would also like to know what is better acetone or 91% IPA.. I have my HBWR seeds and would like to use Bestine for my defat and Acetone for the last step...any help would be greatly appreciated, thank you.

Ya bestine is just heptane so should work fine for defat. Naptha is much cheaper you can usually find it at any small paint or hardware store.

Can use acetone or IPA for extract however IPA pulls over alot more impurities. Hope I have been of help .
