Glad to have found a place where people discuss menstrual cups outside of the context of selling them! I can't seem to find any information about at least *some* of these concerns.....

I accidentally left my mooncup (UK) under a damp glass in my bathroom and it developed some black marks I assume were mould. I cleaned the marks off, boiled it twice and sterilised it with a sterilising tablet, and I did use it after this, perhaps foolishly, as since then have had two occurences of thrush-like symptoms in the space of a month. Is it safe to use a mooncup after it has had mould on it, even if it has been cleaned?

I'm happy to buy a new one, as I fear that after a few years of trouble-free use it has recently became unlucky somehow--over the past few months I seem to have had thrush following my period more often than not, although this was happening before the mould episode. There is NO WAY I'm going back to tampons and towels.

I had no idea how many different types of menstrual cup are out there, and perhaps I would like a change-there are certainly things i dislike about the mooncup, in particular cleaning the unnecessary web address branding inside the rim. Whatever I buy I would definitely want it to be medical grade silicone, and I'm wondering what laws (if any) regulate what the various brands naming their materials as such. Are there any phrases to look out for that imply silicone is safe, proper silicone when it is actually a mix of things? The ladycup site says they use silicone rubber, so I assume that is a mix. Has anyone flame tested any menstrual cups pertaining to be pure silicone? I wish I had the stem I cut off my mooncup to see what happens.

If menstrual cups made from silicone are non-porous, why are they known to become stained?

Mooncup.co.uk argues that coloured mooncups potentially pose health risks, which seems odd since there are lots of silicone products out there reputed to be safe and it's rare for them to be colourless. I suppose I'd rather be on the safe side but I've often wondered why menstrual cups couldn't look less clinical...well, it turns out there are in fact all sorts of colours, but can this be trusted?

Any help with these questions or pointers to prior discussions along these lines greatly appreciated.

I think I would buy a new one if that one has had mold on it! If you still have thrush symptoms after that, you'd know it was likely not the cup (and you have a spare cup).

I went from a clear Keeper MoonCup to a purple Lunette and haven't had any problems--actually, the Lunette is my favorite of the two! No problems with the dye (and I'm usually sensitive to stuff like that) so far.

LOL! Mooncup poo-poos colored cups. I guess they've forgotten that their original cups were varying shades of yellow, depending on the batch. (See my user-pic.)

Mold is easily clobbered with a 10% bleach solution. Appx 2 tablespoons per cup or 10ml per 100ml. Bleach as in Clorox or whatever brand you put into your laundry to whiten whites. I doubt mold had much to do with your thrush, especially since you said you used to get it before.

Logic says that cups get stained because of the texture on the surface. But I'm the first one to say that my highly textured Lunette hardly stains at all whereas my "smooth" Mooncup stains at the mere mention of blood. So there goes that theory. *shrug* Here in the US, 3% hydrogen peroxide is cheap and readily available in the first aid aisle of nearly every type of store. An overnight soak in the stuff removes the dingy stains.

If you think you'd like another cup, compare the dimensions and capacity of your Mooncup to other brands at http://sizecharts.livejournal.com/ or at any of the other charts at the Community FAQ. I don't know if others are silicone blends or not. But Keepers are latex and MeLunas are TPE. They're the two brands that are not "silicone."

An overnight soak in undiluted white vinegar should also eradicate any mould, particularly if followed by a sprinkle of baking soda. Let it bubble itself out then remove and rinse the cup.

Many thanks for the advice. I might yet try these cleaning tips on the Mooncup...baking soda as in bicarbonate of soda? My gran thought practically any problem could be solved with vinegar and 'bicarb'so I'm interested in giving that a go! And at some point I should also try some bleach solution.

In the meantime Mooncup uk have not answered my enquiries (I wrote to them before i found this group). At this rate it would take forever to get all the answers I would want from them before buying their product again, so instead I have ordered a Coral Lunette.

Lunette have already answered all of my safety/materials questions in their FAQ---legal stuff, phthalates, and even what happens when you burn them! That's what I WANT to know about something that's going to be inside my body for hours and hours! Whereas the Mooncup site just seems to go on about eco stuff, not making beetles sad and so on. It's that eco focus that stopped me from trying cups for years to begin with---bullying graffitti and stickers in public toilets about sanitary products in landfill etc---when the first concern should, in my opinion, be for the actual safety and comfort factors....and why do i have to put up with cleaning the annoying ridgey bits etc?

Kuradi8, I think my Mooncup is one of these yellowish ones too, I always assumed maybe that was the 'natural' colour of silicone but in that case, how do they explain this change of/lack of colour on later ones when they say they have NEVER messed around with colour?!

Thanks to all the really useful charts and advice on here I'm really happy to have been able to make a more informed decision this time round, instead of just going for the Mooncup largely just cos Boots stock it---there's loads of stuff in Boots that isn't good for me. I'm not saying Mooncup are bad--they just don't seem to have the right kind of information out there to convince me their product is good enough. So I do hope the Lunette works out ok.

Women's health comes first
They are expensive I know, but I would be careful, and avoid putting anything with mold, even if washed so it's not visible. What if it could make you sick? No one should take chances with their health, it's too precious.
