Meluna cup gone sticky and disintergrating

I haven't used Melunas more than a couple of times (high cervix), but if you bleached something that specifically said it was not to be bleached--well, now you see why. :/

I think you've posted this on the wrong thread.
This is a thread about meluna cups disintergrating. I'm not looking for a new cup.

Yeah, I'd put money on the bleach being the culprit here. 10:1 is still a fairly strong mix and it looks like TPE reacts badly with chlorine. For future knowledge, you can pop that sucker in a pot of water and boil it on the stove for ten minutes (just make sure the water doesn't boil off and melt your cup) and your cup will be just as sterile, if not moreso, than if you bleach it :)

So i guess this means that women can't use the meluna as protection when swimming in chlorine pools either? How ridiculous.

I don't believe pool chlorine is quite the same substance as bleach (and it's obviously far, far weaker because it doesn't burn our skin off when we swim in it)--and furthermore, unless your cervix is practically knocking at your entrance, the cup wouldn't even come into much if any contact with the water while being worn.

Chlorine in swimming pools is diluted way more than 10:1.

Wow, now you see why the company says not to use household bleach.
If you wanted to use bleach, you could have used Milton tablets. They are a more stable, acceptable form of bleach called Sodium dichloroisocyanurate. The bleach and sodium dichloroisocyanurate are closely related in the same family of hypochlorites. For healthcare sterilization applications, the powdered form is found to be as effective if not more effective and much more stable than the liquid compound. Since you can not use anything you can not bleach,(I don't blame you) those are an excellent option in the future.
As for the cup melting, did you both pour the boiling water over it and then soon after clean it with bleach or vice versa? If so, it could be that the two processes performed together before giving the material time to recover, perhaps one process weakened it making it permeable and the other destroyed the bonds that kept it intact. Just a speculation.

I used Milton's sterilizing tablets on my Lunette and it did something similar. I let it sit in the Milton's water overnight and the cup feels extremely sticky and greasy. Maybe I used too much of the tablet in the small skiing of water I used. I broke it into small pieces.
