Add 1/2 cup baking soda right over the towels. Don’t worry about using the dispenser, just pour right over the towels. For a standard washer, use 1 cup of baking soda and add it to the towels and then fill with water. DO NOT ADD SOAP OR VINEGAR, ADD NOTHING BUT BAKING SODA! Run a full cycle using hot water for the wash and rinse cycle. You will be absolutely amazed on how fresh the towels smell. Dry fully and then fold and use!
