7 Ways to Keep Your Bottleless Water Cooler Clean

So, you made the smart move. You ditched the bulky bottles and switched to a bottleless water cooler. It’s cleaner, more efficient, and miles ahead when it comes to sustainability. But like any appliance that gets used daily, your cooler still needs a little attention to keep running at its best.

At Office H2O, we design our water systems to be low-maintenance, high-performance, and built for modern workplaces. That said, even the best machines benefit from a few regular cleaning habits – especially when you want to keep the water fresh, the surfaces sanitized, and the whole setup looking sharp.

Here are seven easy ways to keep your bottleless water cooler clean, efficient, and ready to hydrate.

1. Wipe Down the Exterior Regularly

It sounds simple, but you’d be surprised how many people skip this step. The outside of your cooler, especially the dispensing area, is a high-touch zone. Employees, guests, and clients use it throughout the day, which means fingerprints, dust, splashes, and the occasional coffee cup dribble can build up quickly.

While the exterior of our units have an anti-microbial coating, you should still make it a habit to keep it clean. So, take a few seconds at the end of the day to wipe down the exterior with a soft cloth and a gentle, non-abrasive cleaner. Pay close attention to the drip tray, spigots, and touchless sensor area if your cooler has one.

Keeping it clean on the outside not only maintains hygiene but also helps your space look more polished and professional.

2. Empty & Sanitize the Drip Tray

Drip trays are the unsung heroes of water coolers. They quietly catch spills and overflow, but they don’t clean themselves. Over time, standing water in the tray can become a breeding ground for bacteria or develop an unpleasant smell.

Remove the tray, empty it, and give it a quick wash with warm soapy water. For extra cleanliness, follow up with a sanitizing solution that’s safe for food-contact surfaces. Make this a weekly habit, or more often if your team uses the cooler heavily.

3. Don’t Ignore the Filter Replacement Schedule

One of the biggest perks of a bottleless water cooler is built-in filtration. But even the best filters don’t last forever. When filters go unchanged for too long, they can reduce water flow, affect taste, and allow contaminants to slip through.

At Office H2O, our systems include high-quality carbon or reverse osmosis filters that are designed to last, but only if they’re replaced on schedule. Our service team handles this for you, but if you’re managing a system in-house, make sure you know your filter’s lifespan and mark your calendar accordingly.

Clean water starts with a clean filter.

4. Don’t Dump Anything But Water Into the Drip Tray

Keep in mind that the drip tray isn’t a mini sink. Pouring leftover coffee, tea, or energy drinks into it might seem harmless, but those liquids leave behind residue and odors, and can attract mold. We’ve seen everything from cold brew to protein shakes dumped in, and it always leads to a mess. Additionally, rinsing cups under the water cooler spout can also cause contamination and should be avoided. So, avoid the headaches (and a clogged drain) by sticking to water-only in the tray, and encourage your team to use the kitchen sink for everything else. It’s a small habit that helps keep your cooler clean, safe, and pleasant to use.

6. Sanitize the Dispensing Nozzles Regularly

The nozzles are where water flows out and bottles get refilled. If those nozzles aren’t kept clean, you risk cross-contamination between users and cups.

Use a food-safe sanitizer or a water-and-vinegar solution to wipe down the nozzles at least once a week. For high-traffic areas like warehouses, distribution centers, or shared medical spaces, you may want to bump that up to every couple of days. It takes less than a minute and goes a long way in keeping the water you serve as clean as the system that dispenses it.

7. Report Unusual Smells, Tastes, or Noises

This isn’t technically a cleaning task, but it’s part of keeping your cooler in good condition. If you or someone on your team notices the water tastes off, smells strange, or the machine starts making unusual sounds, don’t wait – give us a call!

These signs could mean the filters are overdue for replacement, something’s clogged, or an internal component needs service. Catching issues early prevents bigger problems later, and keeps your team’s trust in the water they’re drinking.

When you’re an Office H2O customer, you don’t have to troubleshoot on your own. Our local support team is just a call away, and we’ll take care of whatever’s going on.

Better Habits Lead to Better Drinking Water

Your Office H2O bottleless water cooler is built to last, and it doesn’t require much to stay in great shape. A few simple habits, a little attention to detail, and support from a reliable provider go a long way in keeping your hydration station fresh, clean, and ready to go.

If you’re already a customer, our service team can handle most of this for you. If you’re not, and you’re tired of managing water coolers that need constant attention or don’t deliver on quality, we can help you make the switch.
