It is best to wash a sleeping bag in a front-loading washer, as a top-loader can cause damage due to its agitator. Begin by setting the washer to a gentle cycle and adding the recommended amount of detergent. Select the lowest water temperature setting when washing a sleeping bag, as warm water can damage synthetic fibers. Finally, remove the sleeping bag from the washer and inspect whether there are any signs of mildew or mold.
