Yes. Improper cleaning is a major factor that could damage your cup, such as putting it in the dishwasher (it can withstand the heat, but the chemicals in the dishwasher are another story). Improper storage is also another risk factor. Always wash it properly, and then store it in its pouch and away from extreme temperatures, children, and pets. If you treat it well, your Reusable Menstrual Silky Cup should last you up to ten years.
