I'm no chemist so someoneplease step up and let me know if I'm wrong about that.
Found this on Amazon.com 99.85% slightly less than a liter for 10 bucks.
99+% Methanol, 950 ml Bottle with Child Safety Cap: Amazon.com: Industrial & Scientific
Sir, I think you may be on to something. Yes, methanol (all alco-base solvents) are hygroscopic and will absorb water vapor from the air as soon as it is exposed. Keep the cap on when not in use.
The $14/liter from Amazon (delivered) looks like a good choice. If it starts at 99%+ it should be a winner!
