Well, I went to boil my Divacup today and accidentally left it in the water until it the water boiled dry. There was no water in the pot! I only realized it when I smelled burning. Well, I rushed over to take my Divacup out and at first it looked burned but after I washed it off, it seemed to just be dried water. Other than that, it looks fine, no burns but with a bit of a burnt smell on the inside. There are no visible marks and the silicone is as thick as it was before and there is no visible staining. Can I still use it, or should I think about a replacement?
