How to Clean a Washing Machine Safely: Front-Load and Top-Load Steps

Learn how to clean your washing machine safely with step-by-step instructions for front-load and top-load models. Use common household products like vinegar, baking soda, bleach, and hydrogen peroxide to keep your washer fresh and odor-free.

How to Clean a Washing Machine Safely: Front-Load and Top-Load Steps

Before You Start: Unplug the Washer and Gather Supplies

Before any cleaning or maintenance, unplug the washing machine from the power outlet. This reduces the risk of electric shock. Do not attempt to clean the machine while it is plugged in.

Gather the supplies you will need: white vinegar, baking soda, liquid bleach, 3% hydrogen peroxide, a sponge, and a clean, dry cloth. These common household items are sufficient for the cleaning methods described below.

Check your washer’s manual for any manufacturer-specific cleaning instructions or warnings. Some models may have particular recommendations or restrictions.

Do not mix cleaning agents. Use each product in a separate step as described. Mixing vinegar and bleach, for example, can create hazardous fumes.

How to Clean a Front-Loading Washing Machine with Vinegar and Baking Soda

Front-load washers develop musty odors because moisture gets trapped in the rubber gasket and drum. A monthly clean with vinegar and baking soda removes detergent residue and helps control mildew smells. Start with an empty machine and make sure it is unplugged before you touch any surfaces.

Set the washer to the hottest, longest cycle available. Pour 2 cups of white vinegar and 1/4 cup of baking soda directly into the drum, not into the detergent drawer. The vinegar breaks down mineral deposits while the baking soda neutralizes odors. Let the machine run the full cycle without interruption.

Once the cycle finishes, open the door and inspect the rubber gasket. Lift the fold of the gasket and wipe along the entire seal with a damp sponge. This area collects lint, hair, and soap scum that the wash cycle cannot reach. Also wipe the inside of the door glass and the detergent drawer, then dry every surface with a clean, dry cloth. Pay extra attention to the gasket folds and the door seal, because trapped moisture is the main cause of lingering smells.

Repeat this process once a month. Regular cleaning keeps the drum fresh and reduces the buildup that leads to mold and mildew odors. If you notice a strong smell between cleanings, leave the door open for a few hours after each wash to let the interior dry completely.

How to Clean a Top-Loading Washing Machine with Bleach and Vinegar

Top-loading washers collect the same kind of soap scum, fabric softener residue, and hard-water minerals as front-loaders, but the cleaning process is a bit different because of how the tub fills and drains. You will run two separate hot cycles: one with bleach and one with vinegar. Do not combine these products at any point. Each step uses 4 cups of liquid, so measure carefully before pouring.

Step 1: Bleach soak. Set the washer to the hottest and longest cycle with an empty drum. Add 4 cups of liquid bleach directly into the tub. Let the washer fill completely, then pause the cycle or open the lid to stop it. Allow the bleach water to soak for a full hour. This dwell time helps break down residue and brighten the interior surfaces. After the hour, close the lid and let the machine finish the entire cycle, including the drain and spin.

Step 2: Vinegar soak and surface wipe. Once the bleach cycle has fully finished, start another hot, long cycle with an empty washer. Pour 4 cups of white vinegar into the tub and let the washer fill. Stop the cycle again and let it soak for one hour. While it sits, dip a sponge into the vinegar water and wipe down the detergent basket, the softener basket, and the lip of the tub. These areas collect sticky residue that a rinse alone will not remove. Take care not to reach into moving parts. After wiping, close the lid and let the machine run through the rest of the cycle.

Step 3: Dry the interior. When the final cycle ends, open the lid and dry the interior with a clean, dry cloth. Pay attention to the underside of the lid and the rim where moisture tends to pool. Leaving the lid open for a few hours after cleaning also helps the drum air out.

This two-cycle method takes about two and a half hours total, mostly because of the soak times. It is a good idea to schedule it for a morning or afternoon when you will be home. Running this routine once a month keeps the tub fresh and reduces musty odors, but it will not remove every trace of mold or prevent future buildup entirely.

Using a Basket Clean Cycle with a Washing Machine Cleaner

If your washer has a Basket Clean cycle, it offers the most straightforward way to handle monthly maintenance. Start by removing any garments or loose items from the drum. Pour 1 cup (250 ml) of liquid bleach, white vinegar, or a commercial washing machine cleaner directly into the basket. Close the lid, select the Basket Clean cycle, and press Start. Let the cycle run without interruption.

For best results, run this cycle once a month using 1 cup of liquid bleach. This helps keep the tub fresh and reduces musty odors between deeper cleanings. If your machine does not have a dedicated Basket Clean cycle, use the front-load or top-load methods described in the previous sections instead. Those approaches achieve the same goal with the hottest, longest setting your washer offers.

Whichever product you choose, use only one per cycle. Do not combine bleach with vinegar or any other cleaning agent, as mixing can produce hazardous fumes.

Alternative: Cleaning with Hydrogen Peroxide

If you prefer to avoid bleach or vinegar, hydrogen peroxide is a dependable alternative for freshening your washer. Use 2 cups of 3% hydrogen peroxide—the standard strength sold in most drugstores—and pour it directly into the empty drum.

Set the washer to the hottest, longest cycle and let it run completely. The hydrogen peroxide will help break down residue and reduce odors without the strong smell of bleach. Once the cycle finishes, wipe down the interior surfaces with a damp sponge, then dry everything with a clean, dry cloth.

Do not combine hydrogen peroxide with any other cleaning agent. Like the other methods, run this cycle once a month as part of your regular maintenance routine.

How Often to Clean the Washer Tub and Why It Matters

GE Appliances recommends cleaning the washer tub once per month to keep the wash basket fresh and help with mold or mildew odors. This simple routine prevents the buildup of detergent, fabric softener, and hard-water minerals that can cause musty smells over time.

To stay consistent, set a monthly reminder on your phone or calendar. Choose a day that fits your schedule, such as the first weekend of the month, and stick to it. Between cleanings, leave the door or lid open after each use to allow the interior to dry completely. This small habit reduces moisture, which is a key factor in odor development.

Regular cleaning won’t eliminate all mold or mildew, nor will it prevent future issues entirely, but it does keep the tub fresher and reduces the chance of unpleasant smells. If you notice a persistent odor despite monthly cleaning, check the gasket and other damp areas for buildup, and consider whether your machine needs a more thorough inspection.

What to Avoid: Vinegar Amounts, Mixing, and Electrical Safety

Before you start any cleaning routine, remember that the amounts listed in the steps above are the ones to stick with. Using extra vinegar in the hope of a deeper clean can backfire: excessive vinegar can damage the hoses and tubes inside the machine. A cup or two per cycle is enough.

Never mix vinegar with bleach or any other cleaning agent. Combining these can create hazardous fumes that are dangerous to breathe. Always use each product in its own separate step, as described, and rinse the drum between steps if you are switching from one cleaner to another.

Electrical safety comes first. Unplug the washing machine from the power outlet before you wipe down the exterior, clean the gasket, or perform any maintenance. Do not attempt to clean the machine while it is plugged in—water and electricity do not mix.

Finally, keep expectations realistic. Cleaning the tub reduces mold and mildew odors and removes buildup, but it will not eliminate all mold or mildew, nor will it prevent future issues entirely. Regular monthly cleaning is the best way to keep your washer fresh, but it is not a permanent fix.
