When a degreaser and a scrubber sponge won't work to get those racks clean and sparkly, this one hack thankfully will.
First, remove the racks from the oven and place them in your bathtub — that's right. It's a nice wide open space in which you can add all the water you'll need to get the job done. "Note: If your racks are rusted, don't place them in the tub. Instead, toss them inside of a large garbage bag so that the rust doesn't transfer to your bathtub," the site recommended. After that is when a laundry item comes in handy: dryer sheets. One Good Thing advises placing six to eight dryer sheets on top of your oven racks. Next, run hot water over them, making sure to cover the racks with several inches of the steaming water.
One Good Thing then suggests adding about ¼ cup of Dawn dish soap. Let the racks, dryer sheets, and dish soap soak for several hours or overnight. After all, you aren't using your tub while you sleep, right? When the soaking sesh is over, just wipe the racks clean with one of the dryer sheets. For especially resistant grease, use a scrubber sponge and your oven racks will look as good as new.
