So, I purchased a small MeLuna cup because it seemed like the best size for me and didn't realize until after I got it that it was TPE and not silicone. I know from my extensive research on sex toy materials that TPE is not considered quite as safe as silicone. I figured since I'm not sharing my cup it shouldn't matter much, but after using it for a cycle it seems to be holding on to some odor and discoloration, even after boiling, so I'm a little concerned. Has anyone else found this to be more true of TPE cups than silicone? Looking at the size chart and comparison photos, it seems like MeLuna is the shortest cup available. It's only a millimeter difference in length, but going up to the Ladycup or Naturcup looks like a big jump in the pictures and the small MeLuna is sometimes difficult to maneuver into a position far enough inside me that the end doesn't stick out. In fact, I'm tempted to order the totally stemless MeLuna just to help with this problem. I currently have the ball stem variety.
So, what is your opinion on TPE vs. silicone?
And if I'm going to switch to a silicone cup, given that the MeLuna works but only just, which cup would you recommend switching to?

In many cases, how often you change it or wash it (especially with mild soap) can determine how well you will be able to keep stains and odors away. Wearing it longer seems to increase odor and staining for some people. Especially during the last couple days of your period, where the blood is less diluted with mucus.

Some people say a peroxide/water soak helps for the smell. Or even scrubbing with rubbing alcohol.

Also scrubbing really hard with a wash rag seems to help rub stains off. Just make sure the wash cloth is damp and use a tiny bit of soap on it. You can put 3 fingers in the cup so you can hold it more steady while you use the wash cloth.

Some kind of chemical soak is also likely to help with discolouration. Boiling never had an affect on colour as far as I can remember.

I have a lunette (made with silicone) and it seems after each cycle there is slight discoloration. I usually soak in water/peroxide mix for a few hours and it looks like new. I would hate for you to buy a new cup just for a silicone one to do the same! Just my experience :)

I have used both types of MeLuna cup (the old-style Mini and the newer style) as well as the DivaCup. The former is medical-grade TPE while the latter is silicone. I haven't had staining or odour problems with any of them. So far, a combo of thorough rinsing between uses, the occasional wash with mild soap, and boiling after each period seems to have done the trick for me.

Melissa mentioned that longer periods of use may be implicated in cases of staining/odour for some users. I wonder if personal body chemistry may also be a factor? A single perfume can take on a very different scent on different wearers due to its reaction with one's skin. Maybe cups work similarly sometimes? (I'm not at all sure of this, I'm just putting the idea out there. It might explain some cases where wearers were changing /cleaning their cup with reasonable diligence yet were having this happen.)

As for the stemless MeLuna, I've got a large classic stemless and I find it a breeze to insert/remove. It's basically the same length as my beloved medium MINI MeLuna with ring (with the ring included in the length measurement, of course :-) but has significantly more capacity.

This made me think, OP, if you're considering another Meluna and need a shorter cup, you might like the MINI design better.

Discoloration happens, because that's what blood does. Some people have more coloring blood then others. One trick is to rinse the blood off in cold water first, so you don't set the discoloration. Boiling doesn't tackle stains at all, what does is frequent soap, sunning for a few days, or a peroxide soak.

Good points!

One caveat. Sunning is both safe and effective with silicone cups like the DivaCup, but UV exposure will degrade TPE cups (according to the MeLuna FAQ - the word they use is "embrittle"), so that particular solution is best avoided with your MeLuna or any other TPE cup.

True, Meluna's FAQ knows best ! :)

I also wonder about the body chemistry thing. I have had an increase in staining since switching birth controls so i figure it has some role in it! But again just a peroxide soak and the lunette is pretty again
