At work I can’t wash the Lunette menstruation cup with the recommended neutral detergents. Should I wash the cup with perfumed soap or tap water?
Perfumed soaps with unfavourable pH-values might leave the cup with a layer of substances that irritate the mucous membrane; they sometimes contain agents that also keep silicone from functioning properly. It is better to wash the menstrual cup carefully with tap water before using the wrong kind of soap.
