I have a large, square plastic cake holder that I love. It was made in Germany, and the brand, I think, is Emsa (hard to read whether it is an "s," a "y," or a "j"). Back in March, when we visited Indiana, it held the last half of my husband's wonderful chocolate cake that I had made. He was supposed to pick it up from the counter and put it in the truck. (I was taking care of the dog.). An hour into the trip home, he realized that he had left it, but he was not willing to go back for it. Our contractor, who has a key, was supposed to go get it and eat it. He forgot. When we arrived last evening, there it was, still in the holder. The cake has a lot of mold on it. It does not seem to be on the container. Here's my question: Is it possible to sanitize the plastic holder so that I will be able to use it again? It is perfect for holding two loaves of bread while they are rising, so I would hate to lose it, and I don't think I can find another one. (It was from T.J. Maxx maybe six or seven years ago.)
