Between the tasks of emptying the contents of your menstrual cup and putting it back in, many brands recommend sanitizing the cup with mild, unscented soap and water.
But, there may be an occasion when you need to empty your cup in order to prevent leaks but won't have access to running water and soap that's safe for the vagina - for example, when you need to use a porta potty during an all-day park hang or picnic. That's where menstrual cup wipes come to the rescue. They are specifically formulated to clean a menstrual cup when water is not readily available.
It's important to note that these cup wipes don't do double-duty: they aren't meant to cleanse the vulva or vagina - just the cup. If you are prone to irritation or infections, it's also a good idea to check in with your doctor before buying or using menstrual wipes. Of course, following the directions on each individual pack is key, too.
