What is Denatured Alcohol?
Ethyl Alcohol that has had its properties permanently changed. In this case, methanol has been added to make it poisonous so that it can't be drunk by winos without killing them.
You buy it in up to 5 gallons drums at the hardware store.
It is also used to clean LP gas tanks. If you want QUANTITY go to your local
petroleum distributer. They have it in 55 gal. drums for about $100.
Wood alcohol is methanol. Different stuff except for winos with a loaf of bread to strain it through. LOL
