While cleaning your washing machine (the appliance that does the cleaning) might seem counterproductive, it often starts working less efficiently as it becomes grimier. Plus, neglecting to clean the machine may result in lint buildup, clogs, or foul odors. By regularly showing your washing machine some TLC, it'll run better and last longer. Learn how to sanitize and disinfect your machine DIY-style, and in turn, show better maintenance for your washing machine.

6 Steps to Sanitize and Disinfect a Washing Machine

  1. Set Your Washing Machine

    First, you’ll want to set the empty washing machine to its highest setting. Depending on your appliance, this may mean setting it to the “whites” or “heavy” cycle.

  2. Add Chlorine Bleach

    Pour 1 cup of chlorine bleach into the washing machine tray or the drum, depending on the instructions on your machine.

  3. Set the Washer Cycle

    Set your washer to full, hot rinse, and let it run.

  4. Clean the Dispensers and Filter

    Now, it’s time to disinfect the components. "Cleaning the dispensers and filters eliminates buildup of detergents, dirt, debris, and any bacteria or mold-causing agents,” said Asya Biddle, Angi Expert Review Board member and manager of The Dustbusters, a family-owned and operated janitorial company in Williamsport, PA. “You will find that your laundered clothing will smell better and be overall cleaner."

    Remove the bleach dispenser, fabric softener dispenser, filter, and other removable parts from your machine. Among the dispenser and filter, you’ll want to clean the inside of the lid. You can soak all the pieces in soapy water or apply white vinegar with a towel and wipe everything down. Vinegar can be useful for dissolving soap scum and removing mineral deposits. 

    If you need to get into hard-to-reach areas, use a toothbrush to scrub. Afterward, return each removable piece to its place.

  5. Do a Final Rinse

    To make sure you remove all the bleach, do one final rinse. This way, you’ll ensure there'll be no bleach residue when you do your next load of laundry.

  6. Clean the Exterior

    The final step is to clean your washing machine’s exterior components. This includes the top, front, and sides. In addition, clean the rubber seal around the door. 

    You can use a combination of chlorine bleach and water and wipe down everything with a towel. Finally, use water to rinse everything clean, and dry it with a cloth.

Additional Questions

Do you need to use bleach?

No. There are other ways to sanitize and disinfect your washing machine, including white vinegar, vinegar and baking soda, citric acid, or hydrogen peroxide.

How often should you clean your washing machine?

How frequently you wash your washing machine depends on how often you use it. A good rule of thumb for how often you should clean the machine is roughly every one to three months. If you’re noticing a bad odor or mildew on your machine, it’s time for a cleaning.

How long does a washing machine last?

On average, you can expect your washing machine to last anywhere from eight to 12 years.
