I've been using my Mooncup for about 9 months now, and it had slowly started turning a yellowish color, but I was knew this was normal and it was discoloring so slowly I really didn't notice. However, after my last cycle, the upper third of the cup has dark brown smudge-ish stains all over it. So my questions are
(1) What can I do to get rid of the stains? I tend to show it off to people, but if it's got these gross stains I'm a little less inclined. My girlfriends think my cup is gross as it is. I tried a dillution of rubbing alcohol for a few hours today, but that didn't seem to work.
(2) Why did it stain all of a sudden? My two hypothesis are, a) I just started on the Nuvaring (I think I posted here about it several weeks back) so I don't know if perhaps there is a chemical reaction or b) I boiled it for the first time just before my last cycle, because I had run a workshop (lol, I posted about that too) and lots of people had touched it.
Thanks in advance!
EDIT: After this cycle, a mild soap scrub and a 1:2 hydrogen peroxide soak worked like a charm. She looks just like new! thanks again.
