Okay, I have a question. I boiled my DivaCup Friday, because I remembered that I forgot to boil it after I used it the weekend before, well....I left it on the stove, and forgot it, when I went to get it out, I noticed that it just had a little brown spot on the side. I checked it, and it wasn't warped, didn't have any melted spots or anything..just that little brown spot that was easily wiped off. Now my question is--Is it safe to still use it without it cracking, or developing a hole, or something? I'm sort of worried about this. Its not dry or cracked, or nothing. Just like I said--had that one brown spot that I wiped off. Still looks totally normal.
