How to Clean a Washing Machine Tub: The Complete Guide
Your washing machine works hard to keep your clothes clean and fresh. But have you ever thought about cleaning the washing machine itself, particularly the tub where all the magic happens? Over time, detergent residue, fabric softeners, lint, and even mold can build up inside the tub, leading to unpleasant odors and less effective washes. Fortunately, cleaning your washing machine tub is straightforward and can help your machine last longer while ensuring cleaner laundry.
Below, you’ll find everything you need to know about cleaning your washing machine tub—including step-by-step instructions, handy tips, and answers to your most burning questions.
Why Cleaning Your Washing Machine Tub Matters
Even though your washer uses detergent and water regularly, the inside of the tub can harbor:
- Soap scum and detergent residue
- Mineral deposits from hard water
- Mold, mildew, and bacteria (especially in humid areas)
- Lint, hair, and other debris from laundry
These buildups can result in:
- Musty or sour smells in clothes
- Reduced washing efficiency
- Unwanted stains on garments
- A shorter lifespan for your machine
Regular tub cleaning keeps your washer running optimally and your laundry smelling fresh.
Types of Washing Machines and Their Cleaning Needs
There are a few styles of washing machines, and while the core cleaning process is similar, a couple of unique points are worth noting:
- Top-Loading Washers: Easier to access and clean the tub; residue may be more noticeable near the agitator.
- Front-Loading Washers: Rubber door gaskets and seals tend to accumulate more mold and residue.
- High-Efficiency (HE) Machines: Use less water, so detergent can build up faster.
Be sure to check your washer’s manual for specific tub-cleaning cycles or recommendations.
Step-by-Step Guide: How to Clean a Washing Machine Tub
What You’ll Need
- Distilled white vinegar or washing machine cleaner tablets/powders
- Baking soda
- A clean cloth or sponge
- An old toothbrush
- Mild dish soap
1. Prepare the Washing Machine
- Remove any laundry from the machine.
- Wipe around the rubber seals and inside the door or lid with a damp cloth and a little dish soap.
- Take out any detergent dispensers or drawers, and soak them in soapy water.
2. Run a Cleaning Cycle
Most modern machines have a specialized “Tub Clean” or “Self Clean” cycle. If your model doesn’t have this, a normal hot water cycle works too.
For Top-Loading Machines:
- Set your washer to the hottest and largest cycle.
- Add 4 cups of distilled white vinegar directly into the tub. This helps break down grime, soap scum, and mineral deposits.
- Start the cycle and let the tub fill with water and agitate for a few minutes.
- Pause the cycle (or simply let it soak) for 1 hour to maximize cleaning power.
- Resume the cycle and let it finish.
- Once complete, sprinkle 1 cup of baking soda into the tub and run another hot water cycle (no clothes).
For Front-Loading Machines:
- Pour 2 cups of vinegar into the detergent dispenser.
- Run the washer on the hottest setting, using the tub clean cycle if available.
- When finished, sprinkle 1/2 cup of baking soda directly into the drum.
- Run a second hot cycle.
Tip: Instead of vinegar and baking soda, you can use a commercially-designed washing machine cleaner as per the package instructions.
3. Clean Dispensers and External Surfaces
- Scrub the detergent drawer and any dispensers with the old toothbrush and soapy water, rinse thoroughly, and replace.
- Wipe down the interior of the door, the rubber gasket (especially for front-loaders), and the exterior surfaces.
4. Tackle the Door Gasket and Other Nooks
- For front-load washers, gently pull back the rubber door seal and clean any hidden moisture, hair, or mold underneath.
- Use the toothbrush to dislodge any stubborn debris.
5. Leave the Door or Lid Open
- After cleaning, prop open the door or lid to allow the tub to dry completely, preventing future mold growth.
Best Practices and Pro Tips
Keeping your washing machine tub clean doesn’t have to be a chore. Follow these practical tips for fresh, efficient laundry cycles:
- Monthly Maintenance: Repeat the cleaning routine once a month, or more often if you notice odors.
- Don’t Overload Detergent: Excess soap can create more residue. Use the recommended amount, especially in HE washers.
- Dry Seals and Dispensers: After each wash, wipe moisture from rubber gaskets and leave the door/lid slightly open.
- Choose the Right Cleaner: Vinegar and baking soda are excellent and affordable, but if your machine is especially dirty, consider a dedicated tub cleaner.
- Avoid Bleach Together with Vinegar: Never mix these—it creates toxic fumes. Use one at a time if needed.
- Check the Drain Filter: Some washers have a drain filter that collects hair and debris. Clean this per your manufacturer’s details.
- Run Hot Water: Occasional hot water cycles (even for laundry) help melt away residue.
Common Challenges & How to Overcome Them
Even regular cleanings can face a few bumps in the road:
- Persistent Odors: If musty smells remain, repeat the cleaning process using a commercial tub cleaner. Check for hidden grime under the gasket.
- Moldy Gasket: Pay extra attention to the door seal, scrubbing gently with baking soda paste if needed.
- Hard Water Residue: Vinegar is especially helpful for breaking down mineral deposits. Consider a water softener if buildup returns quickly.
- Detergent Dispenser Clogs: Remove and rinse thoroughly, scrubbing with an old toothbrush.
Benefits of a Clean Washing Machine Tub
Making time to clean your washer pays off. Here’s why:
- Fresher Laundry: No more sour odors or unexpected stains.
- Efficient Cleaning: Your washer delivers top performance, using less energy and detergent.
- Longer Appliance Life: Prevents grime buildup that can damage internal parts.
- Safer Home: Less mold and bacteria keeps your laundry—and home—hygienic.
Frequently Asked Questions (FAQs)
1. How often should I clean my washing machine tub?
Ideally, give your washing machine a thorough tub clean once a month. If you notice odors, residue, or your household does frequent laundry, consider cleaning more often.
2. Can I use vinegar to clean my washing machine?
Yes! Distilled white vinegar is an effective natural cleaner for removing grime, soap scum, and mineral deposits. Always run a rinse cycle afterward and never mix vinegar with bleach.
3. What if my washer has a “Tub Clean” cycle?
Use it! The Tub Clean cycle is designed to thoroughly clean the inside of the washer. You can add vinegar, baking soda, or a manufacturer-recommended cleaning tablet to help boost results.
4. How do I prevent mold in my washer?
Wipe down the inside of the drum, the gasket (especially for front-loaders), and dispensers after each wash. Leave the door or lid open to allow air circulation, which discourages mold growth.
5. Why does my washer still smell after cleaning?
Persistent odors can mean hidden grime in the door gasket, drain filter, or detergent cup. Clean these areas thoroughly, and if the smell returns, try a dedicated washing machine cleaner. If odors persist, check for plumbing or drainage issues.
