You may notice water spots on silicone that is air-dried. Water spots come from minerals in your water and are not harmful. They can be prevented by towel-drying after washing. To remove water spots, soak the product in a solution of boiling water and several tablespoons of vinegar for about 3 minutes, rinse with water, and wipe dry.
