Methanol = methyl alcohol = wood alcohol. Simplest of the alcohols, more rapid evaporation than ethanol, highly toxic. Ethanol = ethyl alcohol = grain alcohol (distilled from sugars in fermented sugar cane or grain). Next more complex alcohol; the kind people drink. (Everclear = 95% pure grain alcohol) Denatured alcohol = usually ethanol base, "denatured" with unpleasant tasting or toxic substance, often methanol, therefore avoids taxation and regulation of drinking alcohol. Poisonous to drink, but less immediately toxic to use than methanol. Otherwise, similar properties to ethanol. Available as "Shellac Thinner." Rubbing alcohol = usually based on isopropyl alcohol, an isomer (structural variant) of the third alcohol in the chain (propanol); also often contains much water, perfumes, oils, etc. Generally unsuitable for piano work.
