I'm not sure I'm.posting in the right place so apologies if I have. I've had my mooncup for a few years now. It went through a phase of smelling really badly despite me rinsing in between changing, a good soapy scrub at the end of my period plus sterilising and thankfully it doesn't smell anymore. However, it's stained so badly and I just can't get it out. It's mainly round the stem and the ridges. I use a toothbrush and mild baby soap to wash it and use interdental brushes in the holes too. Does anyone have any tips on how to get rid of the yuck? I know it doesn't warrant a new one as it works perfectly fine but I hate how stained it is!
