How to Effectively Clean and Prevent Mold in Your Washing Machine
Understanding Mold Growth in Washing Machines
Washing machines, particularly high-efficiency front-loading models, can become breeding grounds for mold due to their warm, moist, and dark environment. Laundry products, such as detergent and fabric softener, can leave behind residues that trap soil and bacteria, providing the perfect food source for mold spores.
Identifying Mold in Your Washing Machine
Mold often manifests in front-load washers as black or dark spots behind the rubber gasket that seals the door. It can also occur in other areas of the washer, including drainage pipes, detergent and fabric softener dispensers, and around lint filters.
Effective Mold Removal Method
Materials You’ll Need:
- Microfiber cloths
- Large bucket or sink
- Soft-bristled brush
- Protective gloves
- Chlorine bleach (or hydrogen peroxide)
Step-by-Step Cleaning Instructions:
-
Empty the Washer and Dispenser Drawers: Ensure the washer is empty and remove any detergent or fabric softener from the dispensers.
-
Select Washer Settings: Set the washer to a normal cycle with a large load size and warm or hot water temperature.
-
Add Bleach or Hydrogen Peroxide: Pour one cup of chlorine bleach directly into the washer drum for smaller machines or 1/2 cup into the detergent compartment for larger machines. Alternatively, you can use one full cup of hydrogen peroxide. Do not mix bleach and hydrogen peroxide.
-
Start the Cycle: Allow the washer to complete a full cycle.
-
Clean the Washer Drum and Door: After the cycle, use a microfiber cloth to dry the washer door and gaskets. For front-load washers, gently peel back the door gasket and clean the inside with a cloth dipped in a solution of 1/4 cup chlorine bleach and two cups water.
-
Clean the Dispenser System: Remove the dispenser drawers and rinse them thoroughly with hot water. If heavily soiled, soak them in a bleach/water solution for 10 minutes. Clean the dispenser housing on the washer with a cloth dipped in the bleach solution.
-
Clean the Lint Filter: Locate and remove the lint filter. Brush away lint and wipe away mold with a cloth dipped in the bleach solution. Rinse well and air-dry.
Mold Prevention Techniques
-
Use the Correct Amount of Detergent: Avoid using excessive detergent to prevent residue buildup.
-
Skip Fabric Softeners: Fabric softeners can leave behind residues that promote mold growth. Consider using distilled white vinegar instead.
-
Improve Ventilation and Decrease Humidity: Install a fan or air-conditioner in the laundry room and leave the washer door ajar after each load to facilitate drying.
-
Maintain the Washer and Dryer: Ensure the fan in a front-load washer is clean and functioning properly. Check the dryer vent for leaks and blockages. Dry the door gasket after each use and run a cleaning cycle regularly.
