Refrigerator water dispensers are a convenient feature in modern homes, offering chilled, filtered water at the push of a button. However, over time, they can accumulate mold, bacteria, and mineral deposits from constant moisture and infrequent cleaning. These contaminants may cause unpleasant tastes, odors, or even minor health risks if left unchecked.
Regular cleaning keeps your water fresh, safe to drink, and guarantees your dispenser operates effectively for years. In this guide, we’ll show you how to clean and disinfect your refrigerator’s built-in water dispenser step by step, using safe and effective methods you can perform at home.

Materials for Cleaning the Refrigerator Water Dispenser
Gather these simple household items before you begin:
- Mild dish soap
- White vinegar
- Baking soda (recommended for deep cleaning)
- Toothbrush or cotton swabs
- Microfiber cloth
- Warm water
- Towels
Step-by-Step Guide to Cleaning and Disinfecting

Step 1: Unplug the refrigerator
Unplug your refrigerator and place towels under the dispenser to catch water drips.
Step 2: Remove and Clean Detachable Parts
Remove the removable parts, such as the drip tray, spout cover, or nozzle guard. Soak them in warm, soapy water for 10–15 minutes, then scrub gently with a soft toothbrush or cotton swab. Avoid abrasive scrubbers, rinse thoroughly, and dry with a microfiber cloth.
Step 3: Clean the Nozzle and Exterior
Dip a toothbrush or cotton swab in white vinegar and scrub around the nozzle area. For tough mineral buildup, wrap a vinegar-soaked paper towel around the nozzle for 5–10 minutes. Wipe the refrigerator water dispenser surface and control panel with a cloth dampened in mild soapy water. Do not spray the cleaning water directly on buttons or digital panels; moisture can damage electronics. Finish by wiping with a clean, damp cloth and drying completely.

Step 4: Flush the Internal Lines
Mix a 1:1 solution of white vinegar and warm water. Pour this mixture into the dispenser’s reservoir or connect it through the water line, depending on your fridge model. Dispense the vinegar solution through the nozzle for a few seconds to fill the line, then stop and let it sit for about 5 minutes. This allows the solution to dissolve any buildup.
Afterward, run clean water through the dispenser several times until the vinegar smell is gone. Don’t skip rinsing; leftover vinegar can affect the taste of your water. If your refrigerator water dispenser has a replaceable filter, clean or replace it now, following the manufacturer’s instructions. If not, simply continue to the next step.
Step 5: Dry and Reassemble
Dry all cleaned parts thoroughly to prevent mold growth. Reattach the parts, plug in the refrigerator, and run a small amount of water to ensure it’s working properly.
Conclusion
Make it part of your regular home care routine by wiping the refrigerator water dispenser weekly and deep cleaning it every two to three months. For more practical home maintenance and appliance care tips, explore our other guides to keep your kitchen clean.
