How do you remove permanent marker of a wall?
Not all permanent markers are the same. First try rubbing alcohol (this is usually isopropyl alcohol) or any kind of alcohol that you have. That often works. If it doesn't, then a more serious solvent such as a paint remover may be needed. Of course, if you use paint remover on your painted wall, you will also remove some of the paint and you may need to repaint. But you will definitely get the permanent marker off.

How do you distill hand sanitizer in order to make edible alcohol?
Wikipedia has an article on Alcohol Rubs here: http://en.wikipedia.org/wiki/Hand_sanitizer They typically use ethanol (standard drinking alcohol mixed with something to render it undrinkable) or isopropanol ("rubbing alcohol" which is poisonous — not in a good way — if swallowed). A concentration of 60-70 percent is needed. Standard rubbing alcohol should do the trick, as would a 120+ proof liquor, although both will dry out your skin. You could mix in a small amount of glycerine for moisturizing, and possibly a thickener, but you risk diluting the alcohol to where the mixture is no longer effective. A mixture of nine parts 70% rubbing alcohol to one part glycerine should give you a good (but runny) substitute at a lower price.
