So we recently purchased a few teething dummy clips bc let's face it, they're amazing.

But omg don't they get dirty! The string has gone grey and the dummy itself is picking up so much dirt!

Read a few stuff online saying that you shouldn't sterilise them as silicone is naturally bacteria free, but just wondering what you gals thought.

Thanks a bunch!
