Disinfecting Water Fountains

Advice from Dr. Laundry
Q.

I would like to keep the germ content down on desktop fountains. How much Clorox would you recommend I add to a gallon of water which would be used to fill the fountains?

A.

For the situation that you described, I would try the following:

  • You need to make sure the fountains are well cleaned. If previously used, consider washing thoroughly, then running a solution of 1 tablespoon Clorox® Regular-Bleach₂ with CLOROMAX®/gallon of water. This should get rid of any residual bacteria and allow you to reduce the bleach level in the future.
  • Ongoing, I would think that 1 teaspoon Clorox® Regular-Bleach₂ with CLOROMAX®/gallon of water should be sufficient to keep the water fresh. You might want to change it out on a biweekly or monthly schedule to insure it maintains it freshness.
