This is my opinion only. Methanol is just as dangerous as gas in a can with warm temps and pilot lights and such. Methanol is also a racing fuel. Do you have to pay to have racing fuel in the garage? Lye is used to make soap homemade. Your not storing the methanol that long in its true form before mixing and appying to the oil. Byproduct is glycerin with which you may make soap from or compost or recoup you methanol from. Just let everyone your concerned with know. There should not be any fumes cause they are dangerous to you anyway.
