Between each use, wash your hands and the Disc with fragrance free pH balanced soap (such as the Cora Cup Cleanse). Air dry. Between each cycle, sanitize your disc by boiling it in water for 5-7 minutes.
After the Disc is cleaned properly and air dried, it's important that you store it in a place where it will remain clean in-between uses. Depending on where you purchased the Cora Disc, you will have one of these storage options from Cora: the gold tin, cotton carrying bag, or vegan leather carrying case. That said, any clean, dry, breathable container will suffice.
