How to Clean and Deodorize a Top-Loading Washing Machine Using Vinegar and Baking Soda

Why Cleaning Your Top-Loading Washing Machine Matters

Over time, your top-loading washing machine can accumulate mold, mildew, soap scum, and mineral deposits from hard water. These residues not only cause unpleasant odors but can also transfer onto your clothes, reduce washing efficiency, and even damage the machine. Regular cleaning with natural ingredients like distilled white vinegar and baking soda is a safe, effective, and chemical-free way to restore your washer's performance and keep your laundry fresh.

Materials You Will Need

Distilled white vinegar (at least 2 cups)
Baking soda (about 1/2 cup)
Microfiber cloths (like microfiber cleaning cloths)
Old toothbrush or soft brush
Optional: washing soda booster (washing soda) for heavy buildup

Step-by-Step Guide

Step 1: Prepare the Machine

Ensure the washing machine is empty and the drum is free of any laundry. Remove any laundry that may be inside the machine. Check the pockets of any clothes you may have left in the machine to avoid unexpected surprises later.

Step 2: Run a Hot Cycle with Vinegar

Set your washing machine to the largest load size, hot water setting, and longest wash cycle. If your machine has a “clean washer” cycle, use that instead.
Add 2 cups of distilled white vinegar directly into the drum or into the detergent dispenser if it has a dedicated spot for liquid. The vinegar will break down soap scum, deodorize the drum, and kill mold and mildew.
Start the cycle and allow it to run through the entire wash, rinse, and spin process. The hot water and vinegar mixture will circulate through all the inner workings of the machine.

Step 3: Pause and Scrub (Optional but Recommended)

If you notice visible grime or mold around the lid seal, agitator, or inside the drum after the first cycle, pause the cycle after about 15 minutes of agitation. Use an old toothbrush or soft brush to scrub these areas with a paste made from baking soda and a little water. This helps dislodge stubborn deposits.

Step 4: Run a Second Cycle with Baking Soda

Once the vinegar cycle is complete, start another hot water cycle on the largest load setting.
Add 1/2 cup of baking soda directly into the drum. Baking soda acts as a gentle abrasive and natural deodorizer.
Let the cycle run fully. This second cycle will help neutralize any residual vinegar smell and further lift any remaining dirt.

Step 5: Wipe Down the Exterior and Lid

While the baking soda cycle runs, mix a small amount of water with a few drops of white vinegar. Use a microfiber cloth (microfiber cleaning cloths work best) to wipe down the exterior of the machine, including the top lid, control panel, and edges. For any sticky residue, a little baking soda paste can also work wonders.

Step 6: Clean the Dispensers and Filters

Most top-loading machines have detergent and fabric softener dispensers that can be removed. Take them out and soak them in hot water with a 50/50 mix of white vinegar and water for about 30 minutes. Scrub away any residue with a brush. Reinstall them after they are dry.

Also, check your machine’s manual for the location of the lint filter (if present). Clean it according to the manufacturer’s instructions—often rinsing under running water.

Step 7: Leave the Lid Open

After both cycles are complete and you’ve cleaned the exterior, leave the washing machine lid open for several hours (or overnight) to allow the interior to dry completely. This prevents mold and mildew from returning.

Maintenance Tips for a Fresh Washing Machine

Repeat this deep cleaning process every 1-2 months, depending on usage and water hardness.
Always remove wet laundry promptly after the cycle ends.
Leave the lid open between washes to allow airflow.
Avoid using too much detergent, which contributes to buildup.
Use washing soda booster occasionally for extra cleaning power if you have hard water.

Troubleshooting Common Issues

Musty Odor Remains

If odors persist, try running another cycle with 1 cup of white vinegar. If the problem continues, consider using a specialized washing machine cleaner or checking for blockages in the drain hose.

Visible Mold on Rubber Seal

For top-loading machines with a rubber seal, use a paste of baking soda and water to scrub the rubber gasket. Rinse well and dry thoroughly.

Conclusion

Cleaning your top-loading washing machine with vinegar and baking soda is a simple, cost-effective, and chemical-free way to keep your appliance running efficiently and your clothes smelling fresh. By following this step-by-step guide on a regular basis, you can prevent mold buildup, eliminate odors, and extend the life of your machine. Pair this routine with regular lint filter cleaning and proper detergent usage for the best results.
