I have been using a cup for 14 months now. I started with the Diva Cup in August last year and bought a Fleurcup that I started using in August (which I've only used once at this point). I understand the recommendations for using a perfume-free soap for cleaning a cup, but I was wondering about all natural soaps using essential oils? I use Chagrin Valley's soaps, only the ones that use essential oils (though some of them have additional ingredients like coconut milk or shea butter). I had some issues during the summer with yeast infections during my period while using my cup that went away after my period or on the last two where I have used a pad. I don't know if it was the soap I was using or, something a friend of mine suggested - the heat of summer, since I didn't have a problem in the cooler months cleaning it the same way. But.. maybe it's possible that I was using a soap without any extra "stuff" (like shea butter, coconut milk, etc.) in the cooler months?? I wasn't keeping track. I thought I'd post here and see if anyone else has had a similar experience.
