Our slider lids are designed to close tightly to prevent as many leaks as possible, but that can also cause them to retain liquid underneath the slider. For that very reason, the slider is designed to be removable for thorough cleaning. You can view our video tutorial on how to easily remove and replace the slider lid. Also, we recommend rinsing or dishwashing the lids immediately after each use.
When the lids are used with dark beverages, they may become stained over time. We recommend rinsing them or fully washing them after each beverage is consumed to avoid staining and keep your lid pretty for as long as possible. If your silicone becomes stained, we recommend rinsing or soaking in a baking soda or vinegar solution to lift the stains. We do not sell individual lid pieces separately but replacement lids can be purchased.
