dragonrider, what you are thinking of is ethylene glycol, which is highly toxic.

To answer OP's question, I don't know if it would work at all. I think it would work at least a little bit, but I don't know how effective it would be.
Nick, I looked it up, and you are right. I was thinking of ethylene glycol, which is toxic. Propylene glycol is safe in most concentrations.

1Shina1, sorry about the strong reaction and the bad information --- I really thought you were going to try something dangerous.
