If you have a front-loading washing machine, you can use a commercial washer cleaning product to remove odors. Follow the directions on the product's label to remove sour smells from the washer. You can use chlorine bleach to clean both front- and top-loading machines. Without adding clothing, start the wash cycle with 2 cups of chlorine bleach. Allow the washer to complete a full wash and rinse cycle to remove odors.
Use hot water and white vinegar or bleach to rewash laundry that comes out of the wash with a sour smell. Add either 1 cup of white vinegar or 3/4 cup chlorine bleach at the beginning of the wash to reduce sour odors.
