Proper care can extend the life of your period panties: 1. Rinse: Rinse the panties in cold water immediately after use to remove excess blood. 2. Wash: Wash them in a gentle cycle using mild detergent. Avoid fabric softeners and bleach, as they can damage the absorbent layers. 3. Dry: Air dry the panties to maintain their integrity. Avoid using a dryer, as high heat can degrade the fabric.
