We recommend that The DivaWash be used to clean The DivaCup. We have formulated The DivaWash as a botanically-based all natural cleanser that has been specifically designed to protect the integrity of the silicone material. It is important to use only a natural non-fragrance soap with The DivaCup. Many soaps leave a residue. These can leave a film on the cup that may cause irritation.Other products from HerbsPro
