Disposable Aluminum Oven Liners Keep Your Oven Clean. Reusable Aluminum Oven Liners catch overflows, grease and drippings. Fits all gas or electric ovens. Rust-proof, fire-proof and easy to insert. Use them to bake, roast, reheat and serve. When dirty, just toss them out and insert a new liner. Set of ten, each 18 1/4" x 15 3/4". $14.95
I'm confused. Are they disposable or reusable? Make up your minds. Yes, just toss them out and insert a new liner. Don't clean your oven, ever. And it's not like you have any cookie sheets or even aluminum foil around the house that you could use in place of these.
