Hi all,

I have been using my Mooncup for 2.5 years now, regularly boiling it in water for about 5 minutes before keeping it at the end of each flow. A few months ago, it started to have these rough spots at the base near the stem. Now the spots kinda spread to the whole cup (picture in spoiler as reference). It's only on the outside of the cup, the inside is perfectly smooth like how I first got it. I was searching around the Internet for explanations or solutions but unfortunately couldn't find any. Any ideas? Should I boil it longer or add something into the water to boil it?

Your cup might be coming to the end of its life... It IS 2.5 years old... Might be time for a replacement.

My guess is that boiling it so often might have something to do with it. I have never understood the need to boil a cup unless it was exposed to some potentially nasty microbes. "As clean as cutlery" is clean enough.

Have you tried scrubbing those spots with a toothbrush, with vinegar or bicarbonate ? they could be stains, limestone deposit or less likely, the silicon deteriorating as others mentioned.

Have you tried soaking it for 15 minutes in Milton solution/tablets in water? or a soak/scrub in white vinegar?

you don't 'need' to boil it, for future, and it should last longer than 2.5 years (more like 5-10) so it might be worth emailing Mooncup and see what they say

I agree, it could be limescale. Try soaking in pure white vinegar overnight then scrubbing with baking soda. You can add vinegar to boiling water in the future to prevent this, if that's the problem.

I agree with "As clean as cutlery" is clean enough, it´s no necessary boil so often, the cup can be damaged.
Speak with the mooncup company and explain this, 2,5 years is little time for the cup.

Thanks for the response girls. I took some of your advice and emailed Mooncup for some explanation and advices. They couldn't determine what was the cause of it either and told me best not to use it anymore, plus they also decided to send me a new one. 2.5 years is definitely a little less than what I expected it to last (at least 5 years).
