I have had my diva cup for 9 months now and I love it! I will never go back to tampons and pads. I am trying to get my friends to buy them and make a little diva cup army! Anywoo, in the past several months I have noticed that my diva cup is getting pretty stained. I clean it properly but I just can't get the stains out. I read on the diva cup site before I bought mine that it will become discolored over time and that eventually I will need a new one. Does anyone have any advice on how to get the stains and discoloration out or do I need to break down and get a new one? Thanks!
