Can 99% isopropyl alcohol be used in place of 90 proof grain alcohol?
The former is much easier for me to get, a 5-minute walk. The latter requires a 1 hr car trip and uncertain availability.

I can't find references to using Isopropyl alcohol as a substitute for Ethanol (grain alcohol) but I see mention of using denatured alcohol as a reasonable substitute. I've searched Quinn Jacobson's materials, Mark Osterman's, and John Coffer's. They all say substitute denatured alcohol of grain alcohol isn't available.

No mail order options??
