How to clean refrigerator water line?


Cleaning the water line of your refrigerator is an essential maintenance task to ensure the quality and taste of the water it dispenses. Over time, mineral deposits, bacteria, and mold can accumulate in the water line, affecting the water’s cleanliness and potentially causing health issues. In this article, we will guide you through the process of cleaning your refrigerator water line, helping you maintain a clean and healthy water supply for your household.

Gather the necessary materials

Before you start cleaning the refrigerator water line, make sure you have the following materials ready:

1. Vinegar or a specialized cleaner: Vinegar is a natural and effective cleaner that can remove mineral deposits and kill bacteria. Alternatively, you can use a specialized cleaner designed specifically for refrigerator water lines.

2. Clean cloth or sponge: You will need a soft cloth or sponge to clean the exterior parts of the water line.

3. Bucket or container: Prepare a bucket or container to catch any water that may leak during the cleaning process.

Turn off the water supply

To prevent any water leakage or accidents, it is crucial to turn off the water supply before cleaning the refrigerator water line. Locate the shut-off valve, which is usually located behind or beneath the refrigerator, and turn it off. This step will ensure that no water flows through the water line while you are cleaning it.

Disconnect the water line

Once the water supply is turned off, you can disconnect the water line from the refrigerator. Depending on the model of your refrigerator, the water line may be connected using a push-in fitting, compression fitting, or a screw-on connection. Follow the manufacturer’s instructions to safely disconnect the water line.

Clean the water line

Now that the water line is disconnected, it’s time to clean it. If you are using vinegar, mix equal parts of vinegar and water in a container. Submerge the water line in the vinegar solution and let it soak for about 15-30 minutes. This will help dissolve mineral deposits and kill any bacteria present in the line.

After soaking, use a clean cloth or sponge to scrub the inside of the water line. Be gentle but thorough, ensuring you remove any residue or buildup. For stubborn deposits, you can use a small brush, such as a toothbrush, to scrub the interior walls of the water line.

Rinse and reconnect the water line

Once you have thoroughly cleaned the water line, rinse it with clean water to remove any remaining vinegar or cleaner residue. Make sure all traces of the cleaning solution are removed to avoid any unwanted taste or odor in the water.

After rinsing, reconnect the water line to the refrigerator, following the manufacturer’s instructions. Ensure that the connection is secure and tight to prevent any leaks.

Turn on the water supply and test

Now that everything is reconnected, turn on the water supply and check for any leaks. Allow the water to flow through the water line for a few minutes to flush out any remaining debris or air bubbles. Once the water runs clear and free of any contaminants, you can consider the cleaning process complete.


Regularly cleaning your refrigerator water line is essential to maintain the quality and safety of the water it dispenses. By following the steps outlined in this article, you can effectively clean the water line and ensure a clean and healthy water supply for you and your family.
