The Clean Cookin' Non-Stick Oven Liner" catches spills and splatters in your oven and saves you hours of scrubbing. Simply place it on the bottom of your electric oven, toaster oven or microwave oven. Can also be used in a gas oven, but should not be placed on the bottom. The messy drips wipe away easily with a warm soapy sponge, even after spills get baked on. Fits any size oven, just trim with scissors for a custom fit. Oven safe up to 500° F. Measures 23" L x 16 1/4" W. Not for use with direct contact of food, oven element or open flame.
