You will need to add 3 or 4 tablespoons of baking soda to the mixture. So we are going to create a very powerful combination that will be able to eliminate even the most stubborn fats. The liquid will need to be poured into the bag. You have to make sure that it is not too thick and that the bag does not get punctured.

At this point, the bag should be sealed tightly so that the liquid does not accidentally leak out. Next, place the bag with the rack inside on a flat surface. The oven grill, in the bag, will need to rest for about two hours. If it is very dirty, extend the time, for example, let it sit overnight.

When the required time has elapsed, remove the oven rack from the bag and rinse it under running water. No scrubbing will be necessary. It will be like new and ready to be used again.
