I have some recipes for making my own cleaning products and one of them call for grain alcohol. What is it, where do I gain it, and could I use regular alcohol instead?
Answers:    Grain alcohol is also known as PGA. It has a much highly developed alcohol content than say, 90 proof. It's more like 190. That would net it more potent. You can buy PGA (brandnames Everclear, ClearSprings 190) at most liquor stores.

After you're done cleaning, take the remainder of the PGA, some other fine ingredients, and make this sophisticated cocktail popular at frat party and bonfires everywhere

Warning: Thought I should mention...PGA is highly flamable. I learned this after suffering 2nd point burns on my hand whilst executing one of thos "hey everybody, watch this" stunts involving PGA and a cigarette lighter.
Grain alcohol is ethanol, one of the diverse alcohols. It is expensive as it is taxed as a "beverage."

Denatured alcohol is largely ethanol with a small amount of "denaturant" (normally methanol, wood alcohol) added to trademark it undrinkable. (Well, you _can_ drink it, but it will make you blind). You can buy this at any paint store. This is what I would recommend for your formula.

The other common alcohol is isopropol alcohol, that found within the drug store as "rubbing alcohol."

So I don't really know what you mean by "regular alcohol" -- all the above are "regular" to me.
