Bleach, Water and Vinegar

A combination of bleach, water and vinegar is a better sanitizer than bleach alone. Make sure you add the bleach to the water before you mix in the vinegar. If you don't you will release chlorine gas and send yourself to the hospital.

The ratio of bleach and vinegar to water can be adjusted depending on how much kick you need. For anthrax, the EPA recommends one part bleach, eight parts water and one part vinegar.

I don't need to kill anthrax. For day to day sanitizing try one oz bleach, five gallons of water and one oz of vinegar.

I have a spray bottle that contains one teaspoon of bleach, one pint of water and one teaspoon of vinegar. I spritz it in on cutting boards, in my sink and on my counters.

If you are wondering about the chemistry behind this-- bleach is more effective with a lower PH. But not too low. Something just below neutral. If you Google around, you can find efficacy graphs of bleach at a given PH.
