Underwear
Step 1: Give your underwear a quick rinse under cold water.
Step 2: Throw it in the washing machine with your regular clothes. Wash on cold with mild detergent (no softener or bleach).
Step 3: There are two ways to dry them depending on the undies you have: lay flat to dry for medium absorbency products, or tumble dry on low for high to super absorbency products.
Step 4: That’s it! No ironing needed.
Leakproof Tights & Leotards
Quickly rinse the gusset before you throw your tights or leotard in the machine. Wash on cold with mild detergent, then lay flat to dry. That's it!
Swimwear
Machine wash cold and lay flat to dry. Do not bleach, iron, or dry clean.
