It is generally not recommended to leave a wet towel in the tumble dryer for an extended period. Tumble dryers are designed to dry clothes efficiently and safely. Leaving a wet towel inside the dryer for too long can lead to several issues:
Mold and Mildew: Damp towels left in a closed environment like a tumble dryer can create a breeding ground for mold and mildew. This can lead to unpleasant odors and potential health hazards.
Efficiency: Leaving a wet towel in the dryer can hinder the machine's efficiency. The dryer will have to work longer and harder to dry the towel, consuming more energy and potentially leading to increased wear and tear on the appliance.
Wrinkles and Shrinkage: Extended exposure to heat in the dryer can cause towels to become excessively wrinkled, and in some cases, it may lead to shrinkage.
To avoid these issues, it's best to promptly remove the towel from the dryer as soon as the drying cycle is complete. Shake it out to remove any wrinkles, and then either use the towel or hang it to air dry completely to prevent mold or mildew growth. If you have more towels or laundry to dry, it's best to start a new drying cycle with the next load of laundry.
