How to Clean Washing Machines So Your Laundry Stays Fresh

Key Takeaways:

  • Regular cleaning prevents mold, mildew, detergent buildup, and bad odors in your washer.
  • Clean the drum with vinegar and baking soda, wipe the door gasket, scrub the detergent drawer, and rinse the filter.
  • Leave the door open after each load, use the right detergent, and deep clean every 1–2 months to maintain freshness.

If you’ve noticed an unpleasant smell in your laundry or your clothes aren’t coming out as fresh as they used to, it might be time to clean your washing machine.

Luckily, learning how to clean a washing machine is easier than you might think, and it’s something you can do yourself to restore freshness to your laundry routine.

Why You Should Clean Your Washing Machine Regularly

Your washing machine is one of the hardest-working appliances in your home, often running several cycles each week. However, just like any other appliance, it needs regular maintenance to function properly. Here are a few reasons why cleaning your washing machine is essential:

  • Prevents Mildew and Mold Growth: Humid, damp environments inside the washing machine drum can lead to mildew and mold growth. If left untreated, this can cause a foul odor that lingers on your clothes.
  • Improves Washing Performance: Buildup of detergent residue, soap scum, and dirt can reduce the effectiveness of your washing machine, leading to clothes that don’t come out as clean.
  • Extends Appliance Life: Regular cleaning can help your washing machine run more efficiently and extend its lifespan, saving you money on repairs or replacements.

Now, let’s dive into the steps for cleaning your washing machine.

How to Clean Washing Machine

1. Gather Your Cleaning Supplies

Before you begin, make sure you have everything you need to clean your washing machine:

  • White vinegar: A natural cleaner that helps break down buildup, deodorize, and disinfect.
  • Baking soda: Helps to freshen up your machine and remove odors.
  • Microfiber cloth: To wipe down the drum, door, and exterior.
  • Toothbrush or soft scrub brush: For scrubbing hard-to-reach areas.
  • Warm water: For general cleaning.

2. Clean the Drum

The drum of your washing machine is where the magic happens, but it can also be a hotspot for detergent residue, soap scum, and dirt. Follow these steps to clean it thoroughly:

  • Empty the Drum Make sure your washing machine is empty before cleaning.
  • Run a Hot Water Cycle with Vinegar Set your washer to the hottest setting and run a cycle with 2 cups of white vinegar in the drum. Vinegar helps break down soap scum, mineral deposits, and any other buildup.
  • Add Baking Soda  After the vinegar cycle, add 1 cup of baking soda to the drum and run another hot cycle. Baking soda acts as a deodorizer and can remove lingering smells.

Pro Tip: If your washing machine has a "clean washer" setting, use that for the cleaning cycle. If not, the hot water and vinegar method will work just as well.

3. Clean the Gasket and Door Seal

The rubber gasket around the door, especially in front-load washers, is a common place for mildew and mold to grow, as moisture tends to get trapped there. Here’s how to clean it:

  • Inspect the Gasket Pull back the rubber seal and check for any visible mold or mildew buildup.
  • Scrub with a Solution Create a cleaning solution by mixing equal parts of water and vinegar in a spray bottle. Use a microfiber cloth or soft brush to scrub the gasket, making sure to reach into the folds where mold can hide.
  • Wipe Down the Area Once the gasket is clean, wipe it down with a dry cloth to remove any excess moisture.

4. Clean the Detergent Drawer

The detergent drawer can accumulate soap residue and mold if it’s not cleaned regularly. Here’s how to clean it:

  • Remove the Drawer Most washing machine detergent drawers can be removed by pulling them out completely. Check your user manual for instructions.
  • Soak and Scrub Soak the detergent drawer in warm water for 15-20 minutes to loosen any residue. Use a toothbrush or soft brush to scrub away any buildup.
  • Dry the Drawer After cleaning, wipe the drawer dry and reinsert it into the machine.

5. Clean the Filter (If Applicable)

Some washing machines have a filter that catches lint, debris, and other particles during the wash cycle. A clogged filter can lead to poor drainage and water buildup in your machine. To clean it:

  • Locate the Filter Check your user manual to find the filter location. It’s usually near the bottom of the machine, behind a small panel.
  • Remove and Clean Take out the filter and rinse it under warm water to remove any debris or buildup. Use a toothbrush to scrub away any stubborn particles.
  • Reinstall the Filter Once it’s clean, replace the filter back into the machine.

6. Wipe Down the Exterior

After cleaning the inside of the washing machine, don’t forget to wipe down the exterior. Dust, grime, and water spots can accumulate on the surface, so use a damp cloth to wipe down the machine, including the control panel, knobs, and door.

Tips for Maintaining a Clean Washing Machine

Now that you know how to clean washing machine effectively, here are a few simple tips to maintain its cleanliness, avoid lingering moisture, and prevent future issues:

Leave the Door Open:  After each load, leave the washing machine door open for a few hours to allow the interior to dry. This helps prevent mold and mildew buildup.

Use the Right Detergent:  Using too much detergent can lead to soap residue buildup. Follow the manufacturer’s instructions for detergent amounts and always use the appropriate detergent for your machine type (HE for high-efficiency washers).

Clean Regularly: Perform a deep clean every 1-2 months, depending on how often you use your washing machine. For high-use households, consider cleaning it more often.

Wipe Down After Each Use:  After every laundry session, wipe down the door seal and the drum to prevent moisture from sitting too long.

When to Call a Professional

In most cases, cleaning your washing machine yourself is all it takes to maintain freshness and improve its performance. However, there are times when you may need professional help:

  • Persistent Odors: If you continue to notice unpleasant smells after cleaning, it could indicate a deeper issue, like a clogged drain or a malfunctioning part.
  • Lack of Drainage: If your washing machine isn’t draining properly after cleaning the filter, a professional may need to inspect the pump or drain hose for blockages.
  • Leaks or Water Damage: If you spot any leaks or excessive water buildup, it’s a good idea to call in an expert to ensure there’s no damage to your machine.

Knowing how to clean a washing machine is an essential skill for every homeowner who wants to keep their laundry fresh and their machine running efficiently. By following these easy steps—cleaning the drum, wiping down the gasket, and maintaining the detergent drawer. You can prevent mold, mildew, and detergent buildup that can lead to unpleasant odors or poor washing performance.

Regular maintenance will also ensure your machine works at its best, so your laundry stays fresh and clean. For more tips on home maintenance, check out Liberty Home Guard’s expert resources, and explore how our home warranty plans can help keep your appliances in top condition.
