Keeping your water cooler clean is essential for providing safe, great-tasting drinking water in your home or office. A build-up of mineral deposits, dirt, and germs can negatively impact the quality and taste of your water. Fortunately, cleaning a water cooler is a straightforward process that can be done in just a few steps. In this comprehensive guide, we’ll walk you through everything you need to know to keep your water cooler in tip-top shape.

Supplies You’ll Need

Before diving into the cleaning process, you’ll want to gather the necessary supplies. Having these items on hand will make cleaning quick and efficient.

For cleaning the outside:

Microfiber cloths
All-purpose household cleaner or disinfecting wipes
Small brush or old toothbrush for hard-to-reach areas

For cleaning the inside:

White distilled vinegar
Baking soda
Large pitcher or bucket
Funnel
Long-handled bottle brush
Clean towels

Optional extras:

Rubber gloves to protect hands
Eye protection like goggles

Gather all of these cleaning supplies ahead of time so you have everything close at hand when it’s time to clean.

Cleaning the Outside of the Water Cooler

Let’s start with the exterior of the water cooler. This includes the dispensing area, the bottle cap fitting area, the drip tray, any exterior panels, and the area surrounding the machine.

Follow these steps to thoroughly clean the outside of your water cooler:

Wipe Down All Surfaces

Using your microfiber cloths or disinfecting wipes, carefully wipe down all exterior surfaces of the water cooler. Make sure to scrub away any dirt, dust, fingerprints, and spills.

Pay close attention to the spout and dispensing buttons where hands frequently make contact. Give some extra scrubbing to sanitize these high touch areas.

Use a Brush on Tight Spots

Use the small brush or old toothbrush to gently scrub any tight spots and hard-to-reach crevices. This includes the small openings around dispensing buttons, the underside of the drip tray, and the cap fitting area.

Clean the Drip Tray

Remove the drip tray and give it a thorough cleaning in the sink with hot soapy water. This will remove any mineral deposits or grime that have built up.

Clean Surrounding Areas

Don’t forget to give the areas surrounding the water cooler a good wipe down as well. Clean off the floor underneath and a foot or two on all sides.

Deep Cleaning the Interior

Now it’s time to tackle the interior components like the reservoir, tank, and tubing that deliver your drinking water. This is where mineral scale, biofilm, and bacteria can accumulate if not cleaned regularly.

Here are the steps for deep cleaning inside your water cooler:

Unplug the Cooler

Start by unplugging the water cooler from the power source. You want to make sure it’s powered completely off when cleaning the interior components.

Drain the Reservoir

Following the instructions for your specific model, drain out any water remaining in the cooler’s reservoir or internal tank. This may require removing a drain plug or turning the machine upside down to empty.

Make a Cleaning Solution

In a large pitcher or bucket, mix together equal parts white vinegar and warm water. You’ll also add in a couple tablespoons of baking soda for extra cleansing power.

Alternatively, you can look for powdered cleaner packets made specifically for water coolers and follow the product’s mixing instructions.

Circulate the Solution

Using a funnel, pour the solution into the water cooler’s reservoir. Turn the machine back on and run the cleaning mixture through the dispensers. This circulates it through the internal components to break down mineral scale and kill bacteria.

Dispense about 1/3 of the solution, then let the remainder sit in the tank for 15-30 minutes to soak.

Scrub with a Bottle Brush

Reach the bottle brush inside the reservoir and tube openings. Gently scrub to remove any clinging debris the solution loosened up.

Rinse Thoroughly

Drain any remaining cleaning solution from the water cooler’s reservoir and internal tank. Refill with clean water and run it through the dispensers 2-3 times to rinse everything out.

Dump out the rinse water and repeat with fresh water until it runs clear.

Air Dry

Leave all compartments fully open and allow the cooler to completely air dry before refilling with water. This prevents any moisture from becoming a breeding ground for mold and bacteria.

Optional: Disinfect Daily

For extra protection, fill a spray bottle with half water, half distilled white vinegar or 70% isopropyl alcohol. Lightly mist dispensing nozzles and buttons then wipe down daily.

How Often Should You Clean a Water Cooler?

To keep your drinking water fresh and prevent potential problems, aim to thoroughly clean your water cooler:

Every 3-4 months for the interior.
Monthly for the exterior.
Daily quick disinfecting of key touchpoints.

However, the optimal cleaning frequency can vary based on:

Water Quality – If you have hard water, scale will build up faster requiring more frequent cleaning. With soft water, you may be able to clean less often.
Usage – High traffic office water coolers will need cleaning more regularly than home units only used lightly by a family.
Location – Coolers in dusty environments or around construction may need exterior wipe downs more frequently.
Appearance and Taste – If water quality declines noticeably with more odors, tastes, or dirty appearance, it’s definitely time for a cleaning.

Get to know your water cooler and find the cleaning routine that keeps it looking, tasting, and operating at its best. When in doubt, giving it a refresh is better than letting it go too long.

Troubleshooting Common Water Cooler Issues

In addition to cleaning, perform regular maintenance checks to catch any problems early. Here are some common water cooler troubles and what to do about them:

Leaking or dripping:

Check for misaligned components, cracked hoses, loose fittings. Tighten, reattach, or replace parts as needed.

Buttons not working:

Clean dispensing buttons thoroughly to remove any sticky residue. Check for disconnected wires or electronic issues.

Water flow reduced:

Clean mineral scale out of tubing and valves. Replace filters if needed.

Cloudy or discolored water:

Clean interior and replace filter. If issue persists, may need professional servicing.

Strange smells or tastes:

Clean interior, replacing water, tank, and lines. Sanitize with bleach or vinegar solutions.

Loud noises:

Ensure water bottles are securely positioned. Check for issues with fans and motors. Have professionally serviced.

Although an investment, professional deep cleaning helps optimize performance and prevent costly damages from neglected maintenance.

DIY Water Cooler Sanitizing

For regular upkeep between full cleanings, you can easily sanitize your water cooler’s interior components yourself at home.

Here are two simple sanitizing methods to try:

Vinegar Sanitizer

Mix a solution of 2 tablespoons white vinegar per 1 quart of warm water.
Pour solution into the water reservoir.
Run the sanitizing liquid through the dispenser for 45 seconds.
Let it soak inside the reservoir for 30 minutes.
Drain vinegar solution and rinse 3 times with fresh water.

The acidic vinegar dissolves mineral deposits and kills bacteria for fresh clean tasting water.

Bleach Sanitizer

Mix 1 teaspoon plain unscented bleach per 1 quart of water.
Pour bleach solution into the reservoir.
Run it through the dispenser and let soak 30 minutes.
Drain and rinse thoroughly until bleach smell is gone.

Be sure to use a diluted bleach concentration for safety and to avoid damage to components.

Rinse very thoroughly after using bleach to prevent any residual tastes. White vinegar is gentler if bleach makes you wary.
