What is the most efficent and pratical way to dry alcohol?

First, distill off the alcohol. With ethanol, the best you can get is 95% purity, the remaining 5% is water. There are cheap zeolites and hygroscopic salts such as CaCl2 or NaOH available which can further reduce the amount of water. If you are still not happy, you can get absolute alcohols by using magnesium. And magnesium ribbons or turnings are relatively cheap, too. Place (50-100 g) magnesium in a flask, put some amount of alcohol just to cover the magnesium. Leave for a few hours until you see white magnesium alkoxide being formed on the surface of the metal. Caution: exothermic reaction. Use the tallest distillation column you can find. Do not stir the mixture. Just leave it there. When you have now a lot of magnesium alkoxide you can add more alcohol (up to 2 liters). The alkoxide will destroy any water in the alcohol and you now can distill off your absolute alcohols. For methanol and ethanol, formation of the alkoxide takes only a few hours. For other alcohols, you might need to activate the magnesium by adding some solid iodine and heating to activate the magnesium. Don't distill to dryness. The remaining alkoxide reacts violently with water. Use alcohol-water mixture when disposing them. Sounds fun, doesn't it? =)

rubbing alcohol dries it out.

A drop of rubbing alcohol will dry out the water.

by distilling non-pure alcohol. (you need the proper equipment though - they do this in like high school chemistry class or something like that). But as far as I know, it's impossible to get 100% pure alcohol, because it will absorb some water vapour from the air, so the closest you can get is lika 99,8% or something.

Charcoal (activated charcoal) is a good bet.  It satisfies your requirements. If you heat it up, it will bake out some of the chemicals and moisture it absorbed.  It won't be as efficient in repeated uses, but this procedure can allow it to be reused.  Just bake it out under a fume hood, or -- even better -- in an evacuated oven.

Use a Q-tip and apply it directly to it.. it will dry the area...

Water.  Alcohol absorbs heat quickly but doesn't store it well.

soak a wash rag or hand towel in vodka, chill the cloth then apply to burned area.  Doesn't hurt to take a shot or two or vodka either!  JUST KIDDING.....this is an old treatment but really does help.

You'd need 4 L of dehydrated alcohol and 1 L of water in order to get a 80% solution. Getting a dry solution of ethanol would be a challenge, though, so I would expect it to be closer to 75-77% in actuality (but theoretically 80)

snap them off and swab them with alcohol. X

squeeze them out a bunch and then use a hair dryer

Turn it upside down to get all the liquid out and let it dry.  Then use alcohol on a cloth to remove the sticky stuff.

Drying of solids can be done by vaccum pump. The wet solid is placed in a closed container (ofcourse with one outlet) and the air in it is pumped out by using a vaccum pump (it is just like the pump which is used pump water from wells)\n\nGases are dried by passing over drying agents like sulfuric acid, phosphorus pentoxide, calcium chloride etc., The choice depends on which gas you are going to dry. For example to dry ammonia none of the above mentioned can be used as they react with ammonia. You need quick lime to dry it.
