Soap for Washing Reusable Menstrual Products This is the first soap specially created to effectively and sustainably wash your fabric menstrual collection products. It has been formulated naturally using natural ingredients with whitening, antibacterial, and antifungal properties. It is a handcrafted soap developed especially for our brand (Fluffy & Flow Unipessoal Lda). Although it has been formulated for washing reusable menstrual pads and underwear, it can be used wherever whitening and additional cleaning are needed. Washing instructions: After using the underwear/pad, rinse with cold water until most of the menstrual blood is removed, then rub the soap on the stain.
