Jeez, I use denatured alcohol on my circuit boards from Home Depot or Lowes and it works pretty good for me. I would not try and drink it though, they used to call it wood alcohol or methanol. Different from 200 proof drinkin' alcohol, like Everclear or grain alcohol. That stuff is too expensive to pour on circuit boards. Heck, a few drops in some orange juice will make you stand straight up.
