Learning how to clean a washing machine drum is a simple yet vital step to ensure truly clean laundry.

This guide helps you understand why cleaning your washing machine drum is important. We provide clear, simple steps to tackle this essential chore. We will walk you through various cleaning methods, from natural solutions like vinegar and baking soda to stronger options like bleach. You will also learn how to maintain a clean drum and prevent future buildup. Let us get your washing machine, and your laundry, smelling wonderful again.

Takeaway:

  • Regularly clean your washing machine drum to prevent odors and residue.
  • Use natural solutions like vinegar and baking soda for effective cleaning.
  • Address specific areas like the gasket, dispenser, and filter.
  • Adopt simple habits to maintain drum cleanliness over time.

How do I clean a washing machine drum?

You can clean a washing machine drum using a specialized cleaning cycle or a DIY method. For DIY, use hot water with two cups of white vinegar. Run an empty cycle. Then, sprinkle half a cup of baking soda into the drum and run another hot cycle. Wipe the drum and gasket clean afterwards.


Why Cleaning Your Washing Machine Drum Matters

Have you ever pulled laundry from the machine, expecting a fresh scent, only to be met with a musty smell? It is a common issue. A dirty washing machine drum is often the culprit. Over time, unseen residues collect inside the drum. These residues come from detergents, fabric softeners, and minerals found in your water. They create a breeding ground for mold, mildew, and bacteria.

This buildup affects more than just the smell of your clothes. It can leave marks or stains on your freshly washed items. A dirty drum also reduces your machine’s efficiency. The machine has to work harder to clean clothes. This uses more energy and puts strain on the motor. Regular cleaning helps remove these hidden pollutants. It keeps your clothes truly clean and fresh. It also helps your washing machine last longer. It performs its best when it is clean. This prevents costly repairs down the road.

Ignoring a dirty drum leads to problems. Lingering odors stick to your clothes. Dark spots can appear on the machine’s interior. You may notice a slimy film on the rubber seals. All these signs point to a need for a deep clean. Taking action now saves you frustration later. A clean drum means a clean wash every time.

Essential Supplies for Drum Cleaning

Before you start cleaning your washing machine drum, gather the necessary supplies. You probably have most of these items at home already. Using the right tools makes the cleaning process easier and more effective. Having everything ready saves time and hassle.

Here is what you will need for a thorough cleaning:

  • White Vinegar: This is a natural disinfectant and deodorizer. It cuts through grime and mineral deposits. I always keep a large bottle of white vinegar in my pantry for cleaning. It is amazing how versatile it is. You can use white vinegar to clean your washing machine.
  • Baking Soda: Baking soda is an excellent abrasive and deodorizer. It helps scrub away residue and absorbs bad smells. Combining it with vinegar creates a powerful cleaning reaction. For a strong clean, a mixture of baking soda and vinegar works wonders.
  • Bleach (Optional): If you are dealing with severe mold or mildew, bleach can be a very effective solution. Use it with caution and always follow safety instructions. Bleach offers a strong way to clean your washing machine.
  • Microfiber Cloths or Sponges: These are essential for wiping down surfaces. They help you reach tight spots. They pick up dirt and grime without leaving lint behind.
  • Old Toothbrush or Small Brush: A small brush is useful for scrubbing hard-to-reach areas. It helps with crevices around the door seal or detergent dispenser.
  • Spray Bottle: A spray bottle is handy for applying a vinegar solution to specific areas. It makes it easy to target moldy spots.
  • Protective Gloves: Always wear gloves, especially when using bleach or strong cleaning agents. This protects your skin from irritation.

Gathering these items before you begin streamlines the entire cleaning process. You will be ready to tackle any grime or odor.

Step-by-Step Guide: Cleaning with Vinegar and Baking Soda (Front-Loader)

Cleaning a front-loading washing machine drum requires specific steps. Front-loaders are prone to mold and mildew buildup around the door gasket. My own front-loader sometimes gets a bit musty if I am not careful. This method uses natural ingredients, vinegar and baking soda, for a powerful clean.

Pre-Cleaning Steps

Before you begin, make sure the drum is empty. Remove any clothing or items from the washing machine. Take out the detergent dispenser drawer. You will clean this separately later. Inspect the rubber gasket around the door. Look for any visible debris, hair, or coins caught there. Wipe away any loose grime with a damp cloth. This initial wipe-down removes surface dirt. It prepares the machine for a deeper clean.

Running the Cleaning Cycle

Next, it is time to run the first cleaning cycle. Pour two cups of white vinegar directly into the detergent dispenser or directly into the drum. Select the hottest water setting available on your machine. Choose the largest load size or the “Tub Clean” cycle if your machine has one. Start the wash cycle. If your machine allows it, pause the cycle about halfway through. Let the water and vinegar mixture soak in the drum for 30 minutes to an hour. This soaking helps break down stubborn residue and odors. After the soaking period, resume the cycle to complete it.

Adding Baking Soda and Final Rinse

After the vinegar cycle finishes, it is time for baking soda. Add half a cup of baking soda directly into the detergent dispenser or drum. Run another hot water cycle. Again, choose the largest load size or the “Tub Clean” option. The baking soda helps to neutralize any lingering odors. It also acts as a gentle abrasive. This second cycle rinses away any remaining vinegar and loosened grime. Once this cycle is complete, the drum should look and smell much cleaner.

Wiping Down the Drum and Gasket

Finally, open the washing machine door. Use a clean microfiber cloth to wipe down the inside of the drum. Pay close attention to the rubber gasket. This area often harbors mold and mildew. Pull back the folds of the gasket and thoroughly wipe all surfaces. You might need to use a small brush or an old toothbrush for tough spots. If you see persistent mold, you may need a separate, more targeted mold cleaning method. Leave the door ajar after cleaning. This allows the drum to air dry completely. Air drying prevents new mold growth.

Step-by-Step Guide: Cleaning with Vinegar and Baking Soda (Top-Loader)

Cleaning a top-loading washing machine drum is also straightforward. While top-loaders are less prone to gasket mold, they still accumulate detergent residue and mineral deposits. My top-loader tends to get a ring of grime if I do not clean it regularly. This method effectively cleans and freshens your machine. For more detailed instructions on how to clean a top-loading washing machine, you can refer to our specific guide.

Pre-Cleaning Preparations

First, ensure your top-loader’s drum is completely empty. Remove any laundry items. Check for small objects that may have fallen into the drum. These could be coins or socks. Wipe the agitator or the center post if your machine has one. Use a damp cloth to clean the exterior surfaces of the drum’s interior. This removes any obvious dirt. It makes the deep cleaning more effective.

Initial Vinegar Treatment

Fill the washing machine drum with the hottest water setting. Set it to the largest load size. Add four cups of white vinegar directly into the water. Let the water and vinegar mix for a few minutes. Then, close the lid and let the solution soak for at least one hour. For heavily soiled machines, I sometimes let it soak for several hours, or even overnight. This long soak helps the vinegar penetrate and break down built-up grime. After soaking, run the machine through a full wash cycle. This cycle should drain the vinegar solution and rinse the drum.

Baking Soda Follow-Up

Once the vinegar cycle finishes, it is time for the baking soda. Sprinkle one cup of baking soda directly into the empty drum. Fill the machine with hot water again, using the largest load setting. Let the baking soda dissolve and mix with the water. Allow this solution to soak for another 30 minutes. The baking soda will help neutralize any odors and scrub away remaining residue. After soaking, run a final full wash cycle to thoroughly rinse the drum. This ensures all cleaning agents are gone.

Final Wipe-Down and Maintenance

After both cycles are complete, use a clean cloth to wipe down the inside of the drum. Pay attention to the top rim of the drum. This area often collects residue. Clean the agitator or the wash plate thoroughly. If your top-loader has an agitator, consider how to clean the agitator in your washing machine separately. Leave the lid open for several hours after cleaning. This allows the drum to air dry completely. Proper air circulation prevents moisture buildup. Moisture contributes to future mold and odor problems. Regular cleaning of your top loader keeps it smelling fresh.

Using Bleach for a Deep Clean (When and How)

Sometimes, vinegar and baking soda are not enough for stubborn issues. If your washing machine drum has significant mold, mildew, or a very strong persistent odor, bleach can be a powerful solution. Bleach is an effective disinfectant. It kills bacteria and fungi. However, use bleach with caution. Always follow safety guidelines. Mixing bleach with other cleaners, especially ammonia or vinegar, can create dangerous fumes. Never combine bleach with other cleaning agents.

Bleach Safety Precautions

Before using bleach, take necessary safety steps. Ensure the area is well-ventilated. Open windows and turn on exhaust fans if possible. Wear protective gloves and eye protection. Avoid inhaling the fumes directly. Keep children and pets away from the machine during the cleaning process. Bleach can damage certain materials, so be careful not to splash it on your clothing or surrounding surfaces. If you have a septic system, check your washing machine manual. Some manufacturers do not recommend frequent bleach use for septic systems.

Bleach Cleaning Cycle (Front-Loader)

For a front-loading machine, ensure the drum is empty. Pour half a cup of liquid chlorine bleach directly into the detergent dispenser. Some machines have a specific bleach dispenser. Use that one if available. Do not pour bleach directly into the drum, as it might damage components or stain. Select the hottest water setting and the “Tub Clean” cycle. If your machine does not have a “Tub Clean” cycle, choose the longest, hottest wash cycle available. Start the cycle. Let it run completely through. The hot water and bleach mixture will disinfect the drum and lines. After the cycle finishes, run an extra rinse cycle. This helps to remove any lingering bleach residue.

Bleach Cleaning Cycle (Top-Loader)

For a top-loading machine, fill the drum with the hottest water setting. Allow the water to fill completely. Once the water level is high, add one cup of liquid chlorine bleach directly into the water in the drum. Close the lid. Let the bleach solution agitate for a few minutes. Then, stop the machine. Let the bleach water soak in the drum for 30 minutes to an hour. After soaking, restart the wash cycle. Let it complete the full wash and rinse. Run an additional rinse cycle afterwards. This extra rinse is very important to ensure all bleach is flushed from the machine. It prevents bleach from coming into contact with your next load of laundry. My advice is to then run an empty quick wash with just water to be absolutely sure.

Don’t Forget These Areas: Gasket, Dispenser, and Filter

While cleaning the drum is crucial, other parts of your washing machine also collect grime. These areas include the rubber gasket, the detergent dispenser, and the drain filter. Neglecting them can still lead to odors and poor wash results. Addressing these spots ensures your entire machine is truly clean. This also prevents smells from returning quickly.

Cleaning the Rubber Gasket (Front-Loaders)

The rubber gasket, or door seal, on front-loading machines is a notorious spot for mold and mildew. Water and lint often get trapped in its folds. This creates a dark, damp environment where mold thrives. To clean it, pull back the folds of the gasket. Use a spray bottle filled with equal parts white vinegar and water. Spray the solution onto the moldy areas. Let it sit for a few minutes. Then, scrub vigorously with an old toothbrush or a small cleaning brush. Wipe away all mold and residue with a clean microfiber cloth. You might need to repeat this if the mold is severe. For more detail on this specific task, check out our guide on how to clean the rubber gasket in a washing machine. Always dry the gasket thoroughly after use.

Cleaning the Detergent Dispenser

Detergent and fabric softener residues build up in the dispenser drawer. This creates a sticky mess that can also grow mold. It can also block the proper flow of cleaning agents into your wash. Most dispenser drawers are removable. Pull yours out. Wash it under warm running water. Use a small brush or an old toothbrush to scrub away any caked-on residue. You can soak it in warm, soapy water for 30 minutes for tough buildup. Rinse it well and dry it before putting it back. If your machine’s dispenser is not removable, spray it with a vinegar solution. Then, wipe it clean with a cloth and a brush. For deeper cleaning of this part, learn how to clean the softener dispenser in your washing machine.

Checking the Drain Filter (Lint Trap)

Your washing machine has a drain filter, sometimes called a lint trap or coin trap. This filter catches lint, debris, and small items that might otherwise clog the drain pump. A clogged filter can lead to drainage issues and bad odors. The location varies by machine model, but it is often on the front bottom of the washer, behind a small access panel. Consult your owner’s manual to find it. Place a shallow pan or towel under the filter to catch any water. Slowly twist open the cap. Allow the water to drain. Remove any lint, hair, or debris. Rinse the filter under running water. Use a brush if needed. Screw it back in tightly. Cleaning this filter every few months helps your machine drain efficiently and prevents odors. Knowing how to clean a washing machine filter is key to overall machine health.

Maintaining a Clean Washing Machine Drum

Cleaning your washing machine drum is not a one-time event. Regular maintenance keeps it fresh and efficient. I have found that a few simple habits make a big difference. These practices prevent the buildup of grime and odors. They extend the life of your appliance.

Here are some tips for keeping your washing machine drum clean:

  • Leave the Door or Lid Ajar: After each wash cycle, leave the washing machine door or lid open. This allows air to circulate inside the drum. It helps the interior dry completely. This is especially important for front-loaders, where moisture often gets trapped in the gasket. Air drying prevents mold and mildew from growing. I always do this; it makes a huge difference.
  • Use the Right Amount of Detergent: Using too much detergent can lead to excessive suds. These suds leave behind residue in the drum and hoses. This residue becomes a food source for mold and bacteria. Always follow the detergent manufacturer’s recommendations. Adjust the amount based on your water hardness and load size. Less is often more.
  • Opt for HE (High-Efficiency) Detergent: If you have an HE washing machine, use only HE detergent. These detergents are low-sudsing. They are specifically formulated for machines that use less water. Regular detergent creates too many suds in HE machines. This creates more residue.
  • Run a Monthly Cleaning Cycle: Make it a habit to run a cleaning cycle at least once a month. Use either a commercial washing machine cleaner or the vinegar and baking soda method. Consistent cleaning prevents significant buildup. It also removes any forming odors. This small effort saves you from big cleaning tasks later.
  • Wipe Down After Each Use: Quickly wipe down the inside of the drum and the door gasket after your final load of laundry for the day. This simple step removes excess moisture and any visible lint or debris. It takes only a minute or two. This prevents residue from drying onto the surfaces.
  • Remove Laundry Promptly: Do not leave wet laundry sitting in the machine for too long. Wet clothes create a damp environment inside the drum. This promotes mold and mildew growth. Transfer your laundry to the dryer or clothesline as soon as the cycle finishes.
  • Clean the Detergent Dispenser Regularly: Make sure to clean the detergent dispenser every few weeks. Residue from detergents and softeners can accumulate here. This leads to blockages and odors. A quick rinse or wipe-down prevents this.
  • Consider Water Hardness: If you have hard water, mineral deposits can build up in your machine. These deposits contribute to residue and reduced efficiency. Using a water softener or adding a water softening agent to your wash can help. Regular vinegar washes are also excellent for combating hard water buildup.

By adopting these simple maintenance habits, you keep your washing machine drum consistently clean. This means fresher laundry. It means a more efficient appliance. It also helps avoid the need for intensive deep cleans often.


FAQ Section

How often should I clean my washing machine drum?

You should clean your washing machine drum at least once a month. If you do laundry frequently, or if you live in a humid climate, consider cleaning it every two to three weeks. Regular cleaning prevents the buildup of residue, mold, and odors. This ensures your clothes stay fresh and your machine performs well.

Can I use just baking soda to clean the drum?

You can use baking soda alone, but it is more effective when combined with white vinegar. Baking soda primarily acts as a deodorizer and mild abrasive. Vinegar’s acidity helps break down mineral deposits and kill bacteria. Using them together provides a comprehensive cleaning action, tackling both grime and odors effectively.

What causes the drum to get dirty?

The drum gets dirty from a combination of factors. These include residue from laundry detergents and fabric softeners, minerals from hard water, lint from clothes, and body soils. Over time, these residues accumulate. They create a damp, dark environment ideal for mold, mildew, and bacteria to grow, leading to unpleasant odors.

Is it safe to put clothes in after cleaning the drum?

Yes, it is safe to put clothes in after cleaning the drum. After running the cleaning cycles with vinegar, baking soda, or bleach, run an extra rinse cycle. This ensures all cleaning agents are flushed out. You can also wipe down the drum with a clean, damp cloth. Once dry, your machine is ready for laundry.

Why does my washing machine still smell after cleaning the drum?

If your machine still smells, you might need to clean other parts. Check the rubber gasket on front-loaders for hidden mold. Also, clean the detergent dispenser and the drain filter. These areas often harbor residue and odors. Ensure you leave the door open after each wash to allow proper air drying. This prevents new odor growth.


Conclusion

Keeping your washing machine drum clean is not just about having fresh-smelling clothes. It is about maintaining your appliance’s health and efficiency. Over time, unseen residues build up. These residues lead to musty odors, dirty laundry, and potential machine issues. Taking the time to understand how to clean a washing machine drum solves these problems.

We have walked through effective methods using common household items like vinegar and baking soda. We have also discussed how to use bleach for deeper disinfection when needed. Remember to extend your cleaning efforts beyond the drum. Address the crucial areas of the gasket, detergent dispenser, and drain filter. Consistent maintenance with simple habits, like leaving the door ajar, ensures long-term freshness.

By following these steps, you ensure your washing machine works its best. It delivers truly clean and fresh laundry every time. Make cleaning your washing machine drum a regular part of your home maintenance routine. Your clothes, and your nose, will thank you for it. Start your cleaning today for a fresher tomorrow.
