I bought this oven liner over 10 years ago and it is still doing a great job of keeping my oven clean. I take it out when it gets spills from pies, etc. shake most of it off and wipe it down. Stick it back on the bottom of the oven and it is good to go. I love it and would never not have one in my oven ever again. So easy to clean the oven with this. Well worth the $20.00
