Query: Weird smell, weird taste

As some other reviewers have mentioned, the sheet leaves a chemically taste and smell in your baked products -- it's nothing awful, but noticeable, and, to me, bothersome. I thought it would fade, but after a few attempts I figured my "wear-in" efforts weren't worth all the cookies ending up in the trash. The surface of this baking sheet was easy to wipe clean. However, the grease from the food eventually started soaking into the sheet and leaving circles of grease which I just could not wash out. At the end of the day, I don't think this is any more convenient or better than using parchment. This product is overrated.
