So lets get some Nalcool and cook something in it and find out.

I had been concerned about silicate deposits from the antifreeze being left on the model engine like they are left on the inside of automotive engines so I consulted with a cooling engineer at Cadillac about it. He dismissed silicate formation in such a short time but focused in immediately on the glycol as the solvent involved.
