Freez-It contains menthol, camphor, eucalyptus oil, and isopropyl alcohol.
Menthol, camphor, and eucalyptus oil are mostly harmless in small amounts, but have a strong odor. Same ingredients are in Vicks Vapo-Rub that Mom used to rub on your chest when you had a cold (oops, am I showing my age?).
Isopropyl alcohol, unlike ethyl alcohol (the drinking kind) is toxic if ingested or inhaled in sufficient amounts. If you get an unexplained headache that should be a warning sign.
Get enough folks using that indoors and it may get banned. Although I suppose the venue at Atlanta is large enough it might hardly be noticed? |
I don't think that's the stuff Joe was thinking of. (That Vapco product is not an appropriate substance to be using within a motor.)
The correct stuff is based on various fluoroethane compounds.
MG Chemical sells
a product that works well for this purpose. In fact, I think I've seen 47 using exactly this product, many years ago. 188 has also used it to good effect (primarily in the days before 120 A circuit breakers and CIM motors).
In a pinch, an "air"-in-a-can duster, inverted so that the liquid is released, will work as well (they're generally composed of the same chemicals).
