The short answer: Clean your washing machine once a month by running an empty hot water cycle with two cups of white vinegar, followed by a cycle with half a cup of baking soda, and wipe down the drum, gasket, and detergent drawers. For a deeper clean, remove and soak the dispenser drawer and clean the filter.
Even though your washing machine’s job is to get clothes clean, it can get dirty itself. Over time, detergent residue, fabric softener, and minerals from hard water build up inside the drum, hoses, and filters. This buildup can cause a musty smell, leave stains on your clothes, and even reduce the machine’s efficiency. A dirty machine can also harbor mold and bacteria, which is especially problematic for front loaders because of their rubber gaskets. Regular cleaning not only keeps your machine smelling fresh but also extends its lifespan, saving you money in the long run. For example, a well maintained machine can last 10 to 15 years, while a neglected one might need replacing after 7 to 8 years.
Gather these common household items before you start: white vinegar (at least 2 cups), baking soda (1/2 cup), a microfiber cloth or sponge, an old toothbrush (for scrubbing tight spots), and optionally, a washing machine cleaner or citric acid if you have hard water. Avoid using bleach unless your manufacturer specifically recommends it for your model, as it can damage rubber seals over time. Also, never mix vinegar and bleach, as that creates toxic chlorine gas. If you have a front loader, keep a few old towels handy to clean up any water that might spill.
Follow these steps for a thorough clean, which should take about 1 to 2 hours, including cycle time.
Start by wiping the inside of the drum with a damp cloth to remove loose debris. For front loaders, pay special attention to the rubber gasket (the seal around the door). Pull back the gasket to reveal any hidden mold or grime, and wipe it thoroughly. Use an old toothbrush dipped in vinegar to scrub away any black spots. This is often the source of odors.
Remove the detergent and fabric softener drawer (check your manual for how to pop it out, usually by pressing a release tab). Soak it in warm water with a cup of vinegar for 30 minutes. Then scrub it with a toothbrush to remove any caked on detergent. Rinse and dry before putting it back. While it’s out, wipe the recess in the machine with a damp cloth.
Pour two cups of white vinegar directly into the drum (or into the detergent dispenser if your machine has a self clean cycle). Set the machine to the hottest, longest cycle (often called ‘Clean Washer’ or ‘Heavy Duty’). Run it empty. The vinegar will break down mineral deposits and dissolve residue. If you have a particularly smelly machine, let the cycle pause after it fills, and let it soak for an hour before resuming.
After the vinegar cycle finishes, sprinkle half a cup of baking soda into the drum. Run another hot water cycle (again, the longest one). Baking soda helps neutralize odors and brighten the interior. This two step process is more effective than using either alone.
Most front loaders have a filter at the bottom front, behind a small panel. Top loaders may have a filter inside the agitator or at the end of the drain hose. Check your manual. Place a towel under the panel to catch water. Unscrew the filter (turn counterclockwise) and remove any lint, coins, or debris. Rinse it under water and replace. Clean this filter every two to three months, depending on usage.
Use a vinegar dampened cloth to wipe the outside of the machine, including the control panel (be careful not to get water in the buttons). Wipe the inside of the door glass and the door seal. Then leave the door open to air dry completely.
After cleaning, leave the washing machine door open for at least a few hours, or overnight, to let the interior dry completely. Moisture is the enemy; it causes mold and mildew. For top loaders, leave the lid open. This simple habit prevents future odors.
To keep your machine fresh between deep cleans, adopt these habits:
If you’re in the market for a new machine, consider a model with a self cleaning feature to make maintenance easier. Our research indicates that the GE GFW655SPVDS Review: Best Washing Machine for Most Homes in 2026 stands out for its reliability and ease of cleaning, with a dedicated Clean Washer cycle that simplifies the process. For more options, check out our other top picks in that guide.
Q: How often should I clean my washing machine? A: Run a cleaning cycle with vinegar or a commercial cleaner once a month. If you have hard water or use fabric softener often, increase to every two weeks. Also, wipe the gasket and door after each use to prevent mold.
Q: Can I use bleach to clean my washing machine? A: Yes, but sparingly. Bleach can disinfect, but it can degrade rubber seals and plastic parts over time. If you use bleach, run an extra rinse cycle to remove any residue. For routine cleaning, vinegar and baking soda are safer and more eco friendly.
Q: Why does my washing machine smell even after cleaning? A: Persistent odors often come from a clogged filter or drain pump, or from mold in the gasket. Check and clean the filter (step 5). Also, ensure the machine is level and draining properly. If the smell remains, you may need to replace the drain hose.
Cleaning your washing machine is a simple task that takes less than two hours a month. By following these steps, you’ll extend its life and keep your clothes fresher.
