Cleaning your oven is an important but messy job involving harsh chemicals. But it doesn't have to be! Here's a recipe for a natural oven cleaner using products that won't hurt your hands -- or the environment. Make a paste of baking soda and water. Apply the paste and scrub with steel wool. For stubborn stains, add some salt to the mix. If your oven is self cleaning, you won't need any paste, but make sure to run the cycle well before any big dinner parties are planned to avoid breakdowns, which are more likely to occur right after the cleaning cycle completes.
