To help get rid of the methanol put your Jack in a canning jar and put it in the microwave until it reaches 150 F. Methanol evaporates at 148. When it reaches 150 put a coffee filter on the top. You can also add either Jack Daniels or Apple wood chips to further filter methanol and Fusol oils out. Repeat 2 more times then put the lid on the jar and stick it in a dark cabinet. Check it every few days until it has an aged taste you like. Then strain through a coffee filter and you are done.
