Once you own and use a set of these, you will never be without, and you’ll want to share with everyone you know. I have them in my grill, my oven and my convection oven. I haven’t had to manually clean the bottom of any of them in years. I no longer worry about too much cheese in the lasagna, drippings from a meat glaze, and I can completely smother my chicken in bbq sauce now, and I won’t stress about cleanup. I will simply slide these out, run them under hot water, or even just wipe them down with a paper towel. They will still look brand new, as will the base of my grill and ovens. They are like the no stick surface you’ve always wanted and you don’t have to break your back trying to get things clean. So pile on the sauces and use way more cheese than the recipe calls for. No regrets.
