How to Clean a Washing Machine Naturally With Vinegar and Baking Soda

You may think a machine that cleans clothes would be self-cleaning, but that’s not the case for your washing machine. Cleaning your washing machine prevents the buildup of soap scum, mineral deposits, and mold or mildew—all of which can cause unpleasant odors and reduce washing efficiency. 

“Regular maintenance also helps prolong the life of the washing machine, protects your clothes from staining or residue, and ensures optimal performance,” says Alicia Sokolowski, co-CEO of AspenClean. “Neglecting to clean the washer can lead to persistent odors, clogged drains, and mechanical issues over time.”

Below, learn how to naturally clean your washing machine with vinegar and baking soda for a fresher, more efficient appliance.

The Science Behind These Two Pantry Powerhouses

​​White vinegar contains acetic acid, which effectively dissolves mineral deposits, soap scum, and mildew buildup, while also helping to disinfect the drum and detergent dispensers.

“Baking soda, which is a mild alkali, neutralizes odors, softens water, and gently scrubs away residues without scratching the drum,” Sokolowski explains. “Together, vinegar and baking soda deodorize, clean, and maintain the washing machine—keeping it fresh, hygienic, and operating efficiently.”

Vinegar and Baking Soda Recipe for Washing Machines

Keeping your washing machine in tip-top condition doesn't require expensive supplies or commercial cleansers. All it takes are some household ingredients—and staying on schedule.

Detergent and laundry expert Tom Ceconi recommends cleaning front-loading washing machines monthly and top-loading washing machines every other month. “This helps remove buildup that not only causes odors, but makes your machine work less efficiently and thus not clean as thoroughly,” explains Ceconi. 

Brooke Stafford, appliance repair expert at Domestic & General, notes that general surfaces and machine filters should also be cleaned every four to six weeks. "Keeping on top of these cleaning tasks can extend the life of the machine, and keep clothes cleaner and fresh smelling," she says.

Materials Needed:

• Up to four cups of white vinegar
• Up to one cup of baking soda
• Soft microfiber cloth or sponge
• An old toothbrush (optional)

Instructions for Front-Load Machines:

1. Empty your washing machine, ensuring there are no clothes inside.
2. Clean the gasket by mixing a small amount of vinegar with water, then wipe the rubber door seal, focusing on folds where mildew can form. Use an old toothbrush for hard-to-reach areas, if desired.
3. Add half a cup of baking soda directly into the drum.
4. Add two cups of white vinegar into the detergent dispenser or directly into the drum.
5. Run a hot-water laundry cycle.
6. After the cycle finishes, wipe the drum, door, and gasket with a microfiber cloth.
7. Leave the door open to allow the washer to air-dry, preventing mold growth.

Instructions for Top-Load Machines:

1. Empty your washing machine, making sure there are no clothes left inside.
2. Start a hot water cycle and pause it after the tub fills.
3. Pour four cups of white vinegar into the drum.
4. Add one cup of baking soda directly into the water.
5. Allow the mixture to sit for up to one hour to dissolve buildup.
6. Resume the cycle and allow the washer to drain.
7. Use a microfiber cloth or sponge to wipe the interior of the drum and agitator to remove any loosened residue.
8. Run a short, hot rinse cycle to ensure all residue has been removed.
9. Leave the lid open to allow air circulation and prevent mildew.

When to Call an Appliance Profressional

Sokolowski recommends contacting an expert if your washing machine exhibits any of the following issues: 

• Persistent foul odors that remain even after cleaning
• Water that is not draining or filling properly
• Strange noises, leaks, or excessive vibration
• Mold buildup behind panels or areas that are difficult to reach
• Any electrical or mechanical problems that require internal inspection

“These signs usually indicate problems beyond routine cleaning,” she warns, “and may need professional repair to prevent further damage or safety hazards.”
