[KITKAT]

I use 3 percent bleach.

To make this, put 1 oz of bleach in the bottom of a quart jar. and add 31 oz of water.

Or for those of you who work in liters... 30 ml of bleach in a liter.

3 percent bleach is shown to kill almost every organizm on surfaces after a 20 minute exposure. It is highly water soluble, which means it rinses out well. Finally, it evaporates well, which means any bleach left behind will be gone in a matter of hours.
