Machine wash prior to use. Once used, follow below instructions:

1. PRE RINSE: As soon as possible after wear, rinse until the water runs clear in cold water. Machine wash directly afterwards - or hang dry & set aside for your next load.

2. WASH: Machine wash in delicate/gentle cycle in cold water/30°
We do not recommend washing with fabric softener. Hang to air dry.

Our Period Panties will last 40 washes/two years on average, and like with any reusable period products, they may start to smell at some point. If so, soak them in white vinegar or baking soda overnight prior to machine washing them.
