Few places accumulate more buildups of baked-on grease than oven racks. They are usually tough to clean, but this easy cleaning hack will give you the best results effortlessly.
First, remove the grimy oven racks and take them outdoors so the fumes stay out. Then, following the directions on your preferred cleaner's label, spray the racks liberally.
Remember to spray from about 9 to 12 inches away to ensure an even coating. Next, wrap them airtight with plastic wrap or even a large plastic trash bag.
Let the racks stew in the cleaning liquid for at least 45 minutes, up to overnight. The cleaner will penetrate the grease enough to wipe it off easily rather than endlessly scrub.
