To wash towels in a washing machine, follow these general guidelines:

1. Sort towels by color and fabric type: Wash white towels separately from colored towels to prevent color bleeding. Also, check the care label to determine the appropriate water temperature and cycle for the fabric type.

2. Load towels loosely: Towels need to be able to move around the wash basket for a thorough clean. Some larger capacity washers can handle more towels at once, but take care not to overload.

3. Add detergent and other additives: Use the recommended amount of detergent and any other additives, such as fabric softener or bleach, according to the care label.

4. Select the appropriate cycle: Use a cycle specifically for towels or a normal/regular cycle. A sanitizing cycle can also be used, but may not be recommended for every wash, depending on the towel fabric.

5. Choose the right dryer setting: Once the wash cycle is complete, transfer towels to the dryer right away to avoid any build-up of musty smells. Towels should be dried with the warmest heat appropriate for the fabric according to the laundry care label. Generally, they should be dried on low to medium heat. Use a dryer setting specifically for towels or a normal/regular cycle. High heat and overdrying can cause fabric damage, so be sure to remove the towels promptly once they’re dry.

Different sources provide slightly different recommendations for water temperature and cycle settings. For example, some sources recommend washing towels in warm or hot water, while others suggest using cold water to keep towels clean, soft, and fluffy. Therefore, it is important to check the care label for specific instructions on water temperature and cycle settings.
