Hello, I joined this community two years ago, the same time I got my first Divacup. I tend to only change it twice a day, once in the morning and once at night. The plastic has become very dark and the stem has almost ripped off at the ridge where I use my nails to pull it out. I recently bought another mostly because I left my old one at University and was off to work at a camp all summer but I definitely needed to replace it. How long do people's usually last. Is there a way for me to clean it better? I used to put it in a cup of boiling water could that of killed the lifespan?
