Lingerie is delicate. Made with care from fine microfibers, soft lace and other delicate materials. Wash these delicate items with the love and care the same way we made them. Hand washing in a sink is always recommended but we understand if you want to wash your briefs in the washing machine. If you do, wash it on a gentle program and a maximum of 30 degrees in a laundry bag. Do not use detergents with bleach: this can greatly affect the color of the product. Plus: more detergent does not clean more - use the correct amount.
