Cleaning mold out of your washing machine is essential to keeping it running well and smelling fresh. Here’s a step-by-step guide on how to remove mold from your washing machine, especially in those hard-to-reach spots.
1. Gather Your Supplies
- White vinegar
- Baking soda
- A clean microfiber cloth or sponge
- Old toothbrush or small scrub brush
- Bleach (optional, for severe mold)
- Gloves and a mask (for protection)
2. Clean the Gasket (for Front-Load Machines)
- Check for Mold: Pull back the rubber door gasket (seal) to inspect for mold or mildew buildup.
- Wipe Down: Dampen a cloth with white vinegar and thoroughly wipe the gasket, paying close attention to any black spots or moldy areas.
- Scrub as Needed: Use an old toothbrush to scrub any visible mold or residue from the gasket.
- Optional Bleach Treatment: For severe mold, dip the cloth in diluted bleach (1 part bleach to 10 parts water) and wipe down the gasket. Rinse thoroughly afterward to avoid damaging the rubber seal.
3. Run a Hot Vinegar Cycle
- Fill with Vinegar: Pour 2 cups of white vinegar into the detergent dispenser or directly into the drum.
- Run the Cycle: Select the hottest, longest cycle available (ideally with a soak option, if your machine has it). This will help break down mold, soap scum, and bacteria inside the drum.
- Mid-Cycle Pause (Optional): If possible, pause the machine mid-cycle for 30 minutes to allow the vinegar to soak and penetrate any mold inside the drum. Then resume the cycle to complete the cleaning.
4. Run a Baking Soda Cycle
- Add Baking Soda: Sprinkle about 1/2 cup of baking soda directly into the drum.
- Run Another Hot Cycle: This helps to neutralize odors and remove any leftover vinegar residue. Use the hottest setting available.
5. Clean the Detergent Drawer and Dispenser
- Remove the Drawer (if possible): Take out the detergent drawer and soak it in warm, soapy water for a few minutes. Use the toothbrush to scrub away any mold, detergent buildup, or grime.
- Clean Inside the Compartment: Use a cloth dampened with vinegar to wipe inside the compartment where the drawer sits. Replace the drawer once it’s completely clean and dry.
6. Wipe Down the Drum and Interior
- Final Wipe-Down: After running the cycles, use a clean cloth to wipe down the drum, door, and any other interior surfaces. Be sure everything is dry to prevent future mold growth.
7. Clean the Filter (for Front-Load Machines)
- Many front-load washers have a filter at the bottom. Check your manual to locate it.
- Remove and Rinse: Take out the filter and rinse it thoroughly under warm water. This will help remove any trapped debris and improve drainage.
8. Leave the Door Open to Air Out
- After every wash, leave the door open to allow the drum and gasket to dry completely. This prevents moisture buildup, which can lead to mold growth.
Preventing Mold in Your Washing Machine
- Use the Right Detergent: Use high-efficiency (HE) detergent in HE machines and avoid overusing detergent, as excess can contribute to residue and mold.
- Run a Monthly Cleaning Cycle: Run an empty cycle with hot water and 2 cups of vinegar or a store-bought washing machine cleaner every month to keep mold at bay.
- Dry the Gasket and Door: After each use, wipe down the gasket and leave the door open to dry the machine out completely.
Regularly following these steps can help keep your washing machine mold-free, improving both its cleanliness and lifespan.
