A clean oven with sparkling clean racks makes me happy. My oven is self cleaning, but the racks still need to come out before setting the cleaning cycle to be cleaned by hand.
I've tried a few different methods of cleaning my oven racks. I find that the kitchen sink is just not big enough and I don't like that water splashes everywhere. Sometimes I've taken them outside, placed them on news paper and sprayed them with commercial cleaner and then given them a good rinse, wash, rinse and dry. These methods work but I've found a way that's worth passing on.
Here's an environmentally and almost scrub free way to give you sparkling clean oven racks.
Lay an old large bath towel in the bottom of your bathtub. Lay the racks on top of the towel. Fill the bathtub with the hottest water you can. While tub is filling add 1 cup powdered laundry detergent to the water. Fill tub until racks are completely covered. Leave racks to soak over night or 6-8 hours. Once racks have soaked take a light non abrasive scouring pad and gently rub the racks. You may only need to use a cloth. The soil will have loosened during soaking and will wipe off easily. Rinse well, dry and place back into cleaned oven.
Now go clean your bathtub. A small amount of powdered laundry soap a soft cloth and a little elbow grease will leave you with a squeaky clean tub.
