I have literally been looking EVERYWHERE for an answer to this, and I haven't found much. It makes me feel like I'm the only one with this problem. Haha! My cup has the most disgusting smell I have ever smelled on it. I've been using it for...2 years or so, but only recently has the smell gotten quite this bad. Some people have said to try hydrogen peroxide, but they usually just say for staining, not odour. Some say peroxide ruins silicone? I've also heard baking soda but I'm not sure if that's for odour either. Boiling it really does not help even a bit. I have tried sunlight. I don't have a clue what to do. I actually gag every time I remove my cup because it smells so bad, and I try to wash it really well but that doesn't change anything either. Has anyone else had the smell issue? I can't live with it anymore :/ Thank you so much if you have an answer! :) I have lots of time to try stuff before I need it again so we're good there!

Some people have even said that "are you sure it's not your vagina, and not your cup?" Yes, I am very sure it's not me. How can a cup NOT smell after 2 years in and out of a vagina, really?! LOL! ;) There HAS to be something I can do about it!...

Hydrogen peroxide works well for me. The stuff sold in stores is really dilute (3%), and hasn't damaged my cups. I have a couple, so whatever one I just finished using goes into the peroxide for up to a day. I've heard you can also rub your cup down with rubbing alcohol and let it dry. That might help. Let us know how it goes!

Try soaking it overnight in half white vinegar, half water.

I haven't experienced this myself, as I'm fairly new to cups, but I'd recommend trying baking soda. I would cover it with either dry baking soda, or a paste of baking soda and water. I use that stuff to clean EVERYTHING!

There is a youtube video with someone talking about it she said it smelled like old collard greens. My MeLuna gets that way sometimes but only if I use it on my last day and it takes for ever for the smell to go away no matter what I do to try to get rid of it.

I think it depends on what substance the smell is coming from.

One way to think about this is to find something that the smell will be soluble in, or something that will break it down.

Hydrogen peroxide will bring oxygen to it, and is good at getting blood smell out of fabric, so there's a good chance it will work. Oxidizing the molecules is more or less what it does.

You could use an acid such as vinegar, lemon juice or citric acid (sold as a powder, can mix with water and make much stronger than vinegar.)

There are fewer household products that are a base (opposite of acid,) but that's another option.

Some things dissolve in alcohol. You could use rubbing alcohol (methanol) or vodka (ethanol).

Some smells are in the grease. A grease-cutting soap with no added scents is one option, or a degreaser, or a detergent such as Atsko Sport Wash can get the oil-soluble parts off. Going to more of an extreme, tri-sodium phosphate (TSP) is excellent at getting off grease, but may leave some of its own smell. Another idea would be to rub the cup in oil, such as grapeseed oil, or whatever you have in the fridge, then wipe it carefully off, before using the soap. Sometimes oil soluble things will come off this way.

Whatever you do, be sure to rinse the cup well afterward, so as not to leave any residues that could irritate things later.

Leave it on a sunny windowsill for 2 or 3 days. This method is fine for silicone cups and worked for me. Not recommended for MeLunas, which are a different material.

I second the hydrogen peroxide. I had a cup I washed and left in a window with no effect on smell. A day in the hydrogen peroxide fixed it right up. :)

What I have done is worn the cup when I am not on my cycle. The vagina is a self cleaning oven so if you wear the cup when you are not on the cycle it gets rid of the smell. Least it has worked for me. I haven't had that problem in quite a while as when you wear the cup for long periods of time on your cycle without emptying the blood will make it smell worse.

I was also afraid to use hydrogen peroxide so I left mine in the sun. I put it in a bowl in the window and left it until the smell was gone. It took a while though - probably over a week. But the smell was completely gone and hasn't returned!

Thank you so much everyone! I tried the hydrogen peroxide, and it worked...kind of. I mean, it is sooo much better than it was! I don`t have to gag when I use it anymore :P Still not nice smelling, but better. I also didn't leave it in the cup that long. But anyway, if I have this problem again I will try some of your other suggestions. Don't really want to use up all my mom's hydrogen peroxide all the time, haha! Thanks again :)
