I am familiar with MH, except I used it to clean wood before treating it as a boat builder!! I got to get you guys on solvent free extracts, you sir just signed up for a flight of solvent free treats when I make it across the water! Another topic for another time, when you mentioned Ethanol I thought of Denatured Alcohol - I used this on finer wood finishes as MH does leave residue that inhibits chemical bonding in epoxy resins and would suggest checking that out maybe even for extracts as it evaporates completely * oh course I cannot condone it, have no idea if it is safe, never tried, likely won’t buuutttt if one was so inclined might be worth a look over MH Get mine at Industrial Paints and Plastics, not as cheap as MH but IME a much more complete evaporation. Thanks again Spark
Edit: I’m pretty sure the MH has the same warning on them but the “Klean-Strip” Denatured alcohol I use has poison labels on it _ @TerpSneeze is not responsible for those who choose to listen to his medicated ramblings
