Hi, I'm Jennifer Cail. On behalf of Expert Village, I'm going to show you how to clean and maintain your oven. The last step is you want to make sure that the outside of your oven matches the inside and how nice and clean it is. To keep the inside of your oven nice and clean you want to make sure it does prevents spills and splatters so this can be by having some of your food covered. For instance if you are making a turkey, then you want to have it covered with foiled during most of it's baking that will help prevent splattering. Also by having a deep enough roasting pan that will help if you are baking something like a pie where it might spill out over the edge. Then you want to make sure to have either a piece of foil underneath it or you can also put it on a cookie sheet. Both will help prevent spills on the bottom of your oven floor. To clean the outside you can either just use some water on your sponge or you can also use some of your all purpose cleaner just to make sure that your glass stays nice and streak free.
