I tend to enjoy sports and manual labor, so end up sweating all over my glasses a few times a week. Because of this, the oil removal process is the piece in which I'm most interested.

I have used a glass cleaner spray bottle (which was methanol) when that ran out, I just refilled it with 95% ethanol (grain alcohol) and it seems to be fine.

I am curious about RoR and its chemical makeup. Is it that different than an alcohol?
