Cleaning a water cooler is not as difficult as one may think. In fact, it only takes 30 minutes to clean one. You only need to know the essential steps on how to clean a water cooler and what you need to clean it with. Then you can rest assured that your dispenser will always supply fresh-tasting water.

Water coolers are grouped into two major categories – the point-of-use (POU) water coolers and bottled water coolers.

Either way, a good knowledge of how to clean the water cooler is important; which is what we are going to address in this article.

So, at the end of this article not only will you learn how to clean a water cooler, but you will also learn how to clean a top-loading or bottom-loading cooler as well as identify the essential items for cleaning any water cooler.

Here are a few steps on how to clean a top-loading water cooler:

Unplug the power cord

Before you commence cleaning, ensure you remove the power cord from the AC outlet so that you don’t trip on the cables or get electrocuted during the cleaning process.

Remove the bottle carefully

If the bottle is not empty before you clean the dispenser, carefully remove it to avoid spilling the remaining water.

Then check the bottle holder and valve for a buildup of dirt or mildew. If you haven’t cleaned your water cooler in a while, you will most likely notice some there.

In the event that that’s the case, use a paper towel to wipe it away. If the dirt is still stuck, make a small solution of baking soda and water and scrub off the dirt with a brush.

Clean the drip guard

For some water coolers, the drip guard is removable. If yours can be removed, rinse it under a running tap and clean it with the disinfecting solution.

If there are stubborn stains, scrub properly with a brush and the baking soda solution. Then, rinse properly and leave it to dry.

Clean the water guard

Some water dispensers have water guards that puncture the top of the water bottle when you install it. Remove this guard, wash it properly under a tap and then apply your cleaning solution. Rinse it properly and leave it to dry.

Clean the reservoir

If you still have some of the cleaning solution left, you can use that to clean the reservoir. Otherwise, make some more and ensure that it has the right concentration while you are at it.

Pour the solution into the reservoir and let it sit for about five minutes before draining it through the spigots. Make sure you use both spigots to drain the reservoir to ensure that they are both clean.

Thereafter, pour two gallons of clean water to rinse the reservoir. When this is emptied, pour a gallon of water into the reservoir and smell it (if you used bleach solution) or taste it (if you used vinegar).

If there are still traces of your cleaning agent, you will need to repeat the rinsing process to remove traces of the solution.

Once the unit is thoroughly cleaned, allow the parts to dry completely.

Return removed parts

As soon as the parts are dry, replace them and place a new bottle on your water cooler.

Plug the water cooler to an AC outlet and allow your water to cool for thirty minutes to an hour before using it.

Fontis Water advises water cooler owners to clean their units thoroughly at least once in every 6 months. In this video, it shows how to clean a water cooler thoroughly. Check it out.

How To Clean A Water Cooler – Bottom Loading

Cleaning a bottom-loading water cooler is similar to cleaning a top-loading cooler. You will need a cleaning solution, a funnel, and an empty water bottle to clean the cooler.

Here are easy steps on how to clean a bottom loading water cooler:

i. After unplugging the power cord to prevent safety hazards while cleaning, remove the bottle from the bottom of the cooler and open your spigots to drain the water left in the reservoir.

ii. Mix the cleaning (disinfecting) solution in your empty bottle and connect your bottle filled with cleaning solution back to the water cooler.

iii. Your cleaning mixture should move to your reservoir. Let it sit there for about 5 to 10 minutes to get it clean.

iv. If you pull it out too quickly, you might not get all the dirt off.

v. Drain your reservoir by opening the spigots. This way you’re also passing the cleaning solution through the spigots.

vi. Fill your empty bottle with clean water and install it in your water cooler. Rinse the reservoir and drain the water through the spigots.

vii. Continue the process until there’s no trace of your disinfecting solution left in the water.

viii. After cleaning your water cooler (both top and bottom-loading types), remove the water dip tray cover and drain excess water from it. Use a clean cloth and your disinfecting solution to clean it.
