Cleaning a moldy washing machine without using bleach or chemicals may require a little extra effort, but it's possible. Here are some natural and eco-friendly methods to clean a moldy washing machine:
Vinegar: White vinegar is a natural antibacterial and antifungal agent. Add two cups of white vinegar to the detergent dispenser or directly into the drum. Run a hot water cycle (preferably the longest and hottest setting) without any clothes inside. The vinegar will help kill the mold and remove any foul odors.
Baking Soda: Baking soda is another natural cleaning agent that can help eliminate mold and mildew. Sprinkle half a cup of baking soda directly into the drum and run a hot water cycle. The baking soda will help remove stains and neutralize odors.
Citric Acid: Citric acid, found in lemons and many other citrus fruits, has antimicrobial properties and can help clean and disinfect the washing machine. Dissolve two tablespoons of citric acid powder in hot water and pour it into the detergent dispenser. Run a hot water cycle without any laundry.
Hydrogen Peroxide: Hydrogen peroxide is a mild disinfectant and can be used to kill mold. Mix equal parts of hydrogen peroxide and water and spray or pour the solution into the drum. Let it sit for 30 minutes and then run a hot water cycle.
Essential Oils: Some essential oils like tea tree oil, eucalyptus oil, or lavender oil have natural antibacterial properties. Add a few drops of your chosen essential oil to a cup of water and pour it into the detergent dispenser. Run a hot water cycle without clothes.
Manual Cleaning: For stubborn mold in hard-to-reach areas, you can manually clean the inside of the washing machine using a soft brush or toothbrush dipped in a mixture of vinegar and water.
After using any of these natural cleaning methods, it's a good idea to run an additional cycle with plain hot water to rinse away any remaining residue. To prevent mold from returning, leave the washing machine door open between uses to allow it to dry completely, and avoid leaving wet clothes inside for an extended period.
Please note that while these natural methods can help clean a moldy washing machine to some extent, they may not be as potent as chemical cleaners like bleach. If the mold problem is severe or persistent, it's best to consult a professional appliance repair service or consider using a mild eco-friendly detergent specifically designed to remove mold and mildew from washing machines.
