Cleaning out your water cooler every time you change the bottle will prevent mold and other pathogens from growing in the wet environment. Some companies suggest using bleach, but there is a more natural, safer way to to this. Vinegar is cheap, and if there is any residue of it inside the cooler, it will not harm you or your family when you drink the water.
Step 1
Unplug the water cooler and remove the old, empty bottle. Wait until the bottle is empty before cleaning out the unit.
