If your laundry smells bad when dried in the sun, there are a few potential reasons for this issue, and several steps you can take to avoid it:
Sunlight and Bacteria: Sunlight can help to naturally disinfect and freshen laundry, but if the clothes are not completely clean before hanging them out to dry, the heat from the sun can activate and promote the growth of bacteria and mildew, leading to unpleasant odors.
Air Pollution or Pollen: If you live in an area with high air pollution, smoke, or pollen, these particles can settle on your laundry while it's drying outside, causing it to absorb undesirable smells.
Humidity: High humidity levels can make it difficult for your laundry to dry completely, creating a damp environment that encourages the growth of mold and mildew, leading to a musty smell.
To avoid these issues and keep your laundry smelling fresh when drying it in the sun, consider these tips:
Ensure Clean Laundry: Make sure your clothes are thoroughly cleaned before hanging them outside. If your washing machine has an extra rinse option, use it to remove any leftover detergent residue that can attract dirt and bacteria.
Dry on Sunny and Breezy Days: Choose to hang your laundry outside on sunny and breezy days when the air is drier and cleaner. Avoid drying your clothes outside during high humidity or when there's a risk of rain.
Dry in the Shade: If possible, find a shaded spot to dry your clothes. Direct sunlight can fade colors and break down certain fabrics over time. Drying in the shade can still offer many benefits without the risk of sun damage.
Use Fabric Softener or Vinegar: Adding a little fabric softener to your final rinse or using white vinegar as a natural fabric softener can help keep your clothes smelling fresh after they've dried.
Clean and Maintain Your Washer and Dryer: Regularly clean and maintain your washing machine and dryer to ensure they are operating efficiently and not contributing to any odors on your laundry.
Bring Clothes in Once Dry: Avoid leaving your clothes outside overnight or for an extended period once they're dry. This will help prevent them from absorbing any nighttime moisture or outdoor pollutants.
By following these tips, you can enjoy the benefits of sun-dried laundry without the unwanted odors.
