Running an empty load of laundry through the washer and dryer without detergent can be an effective way to get rid of mildew or musty smells. It is a common practice for cleaning and maintaining your machines. However, there are a few important considerations to keep in mind to ensure you don't damage your appliances or clothing:
Check the manufacturer's guidelines: Before running an empty load, it's crucial to consult the user manual of your washer and dryer. Some machines may have specific recommendations or restrictions regarding running empty loads.
Use hot water (for the washer): Hot water can help to kill bacteria and mold that may be causing the mildew smell. However, again, check your machine's manual to make sure it can handle hot water without any issues.
Do not overload the machines: Even though there are no clothes to wash or dry, overloading the machines can put unnecessary strain on their components.
No detergent or fabric softener: As you mentioned, do not add any detergent, fabric softener, or other cleaning agents to the empty load. The purpose is to let the water and heat do the work without any additives.
Use vinegar or baking soda (optional): Some people use white vinegar or baking soda as a natural deodorizer. You can add one cup of white vinegar to the washer drum before running the empty load. Alternatively, you can sprinkle baking soda in the washer drum to help neutralize odors.
Inspect the machines afterward: Once the cycle is complete, check the washer drum and dryer drum for any remaining signs of mildew or mold. If you spot any, you may want to repeat the process or consider other cleaning methods.
Running an empty load with these precautions should not damage your machines or ruin your clothing. It's important to periodically clean your washer and dryer to prevent the buildup of mold, mildew, and odors. Keeping your appliances clean will also help them perform more efficiently and extend their lifespan. If you encounter any persistent issues with your appliances or are unsure about their maintenance, it's always best to consult the manufacturer or a professional appliance repair service.
