These oven liners were a great investment. Cleaning the oven is near the top of my list of chores I hate to do. Every holiday season I make a large potato casserole that never fails to bubble over onto the floor of the oven. If I don't clean it up right away, it becomes a baked-on mess and creates a smoky cloud. With the liners, everything just wipes up with a paper towel. It's so easy. I've had mine for several years now and they are just fine. I would hate to bake without them.
