Cleaning your water cooler
- Note: Clean your bottled water cooler before every bottle change.
- Unplug cord from electrical outlet of cooler.
- Remove empty bottle (carboy).
- Drain water from stainless steel reservoir(s) through faucet(s).
- Prepare a disinfecting solution by adding one tablespoon (15 mL) household bleach to one Imperial gallon (4.5 L) of water solution.
- Some companies suggest using one part vinegar to three parts water solution to clean the reservoir of scale before cleaning with bleach. Check your manual.
- Note: Other disinfecting solutions may be suitable. Please check with your water cooler supplier/manual.
- Pour the bleach/other disinfection solution into the reservoir.
- Wash reservoir thoroughly with bleach solution and let stand for not less than two minutes (to be effective) and not more than five minutes (to prevent corrosion).
- Drain bleach/disinfection solution from reservoir through faucet(s).
- Rinse reservoir thoroughly with clean tap water, draining water through faucets, to remove traces of the bleach/disinfection solution.
Drip Tray (located under faucets)
- Lift off drip tray.
- Remove the screen and wash both tray and screen in mild detergent.
- Rinse well in clean tap water and replace on cooler.
- Wash hands with soap and warm water before handling. If you choose to use clean protective gloves (ex. latex), discard or disinfect after each use and prior to reuse.
- Note: Protective gloves should never replace proper hand washing and hygiene.
- Wipe the top and neck of the new bottle with a paper towel dipped in household bleach solution (1 tablespoon (15 mL) of bleach, 1 gallon (4.5 L) of water). Rubbing alcohol may also be used, but must be completely evaporated before placing the bottle in the cooler.
- Remove cap from new bottle without touching the surface of the opening to avoid any contamination. Place new bottle on cooler.
