Leaving damp towels sitting in a washing machine for an extended period can create a favorable environment for mildew growth and unpleasant odors. The time it takes for mildew to develop can vary depending on factors such as humidity, temperature, and the cleanliness of the washing machine. Generally, it's best to avoid leaving damp towels in the washing machine for too long to prevent mildew.
If you're unable to immediately transfer the towels from the washing machine to the dryer, here are some guidelines to minimize the risk of mildew:
Time Limit: Try not to leave damp towels in the washing machine for more than a few hours. The longer they sit, especially in a warm and humid environment, the higher the chances of mildew growth.
Air Circulation: If you can't dry the towels immediately, open the washing machine lid or door to allow air circulation. This will help prevent the buildup of moisture and reduce the risk of mildew.
Use a Timer: Set a timer to remind yourself to transfer the towels to the dryer promptly.
Resist Rewashing: If you forget about the towels and they do develop a mildew smell, avoid the temptation to rewash them immediately. Mildew can release spores that could spread to other laundry. Instead, take the towels out and shake off any loose debris, then wash them separately with hot water and a cup of white vinegar to help eliminate the mildew smell.
Keep the Washing Machine Clean: Regularly clean your washing machine, including the detergent dispenser and rubber gasket, to prevent any mold or mildew buildup inside the machine.
In summary, to prevent mildew growth, aim to transfer damp towels from the washing machine to the dryer as soon as possible. If you accidentally leave them for an extended period, take steps to promote air circulation and avoid rewashing them with other laundry until the mildew smell is addressed.
