Keep your oven looking pristine with this non-stick oven liner from Walter Drake. This simple mat ensures that you'll never have to clean the bottom of your oven again. Prevent baked-on messes by placing this oven liner for spills on the bottom rack of your gas or electric oven. Even if some foods or liquids get burned on to the mat, they'll glide right off the non-stick surface when you wipe it clean or put it through a dishwasher cycle. These liners can withstand high heat and are safe to 550° Fahrenheit. Measuring 26" L x 18" W, these oven spill guards are a great size for most standard ovens, but they can also be trimmed to fit as needed.
