Not really lost because I have a good idea of where it is, but this will be my second chapstick that I have forgotten to take out of the washer. The first one was almost empty, so not a huge loss. This new one was just opened last week. I don't think the detergent leaks into the tube, the first one looks fine, smells fine, used a little, so far so good. We shall see in about an hour, for the status of the new one.
