Sanitize your cup before first use and before or after each period. You can do this by boiling your cup, wiping with 70% isopropyl alcohol, or using the Saalt Steamer or Saalt Compact Sanitizer. During your period, you will want to clean your cup at least once every 12 hours. You can do so by rinsing the cup with cold water (to prevent staining) and then washing the cup with hot water and Saalt Wash or another wash that is mild, pH-balanced, fragrance-free, oil-free, and rinses clean with no residue. Comfortable - Saalt Cup is impossibly soft and flexible. The proprietary bulb shape makes it the easiest cup to insert and open, ensuring a seal so comfortable that you forget it's there. It also means you have a consistent leak free and odor free period. The indented stem is the most flexible and comfortable on the market. No abrasive ridges to irritate your skin.
