Next, you will need a bowl in which to place the tablet or detergent. In the bowl, to pour directly on the tablet, you will put hot water so that the contents can dissolve well. Of course, the water should not be too hot, otherwise you could pierce the bag. If the tablet is not completely dissolved, you can use a fork to speed up the process.
You will have to add 3 or 4 tablespoons of baking soda to the mixture. So we will create a very powerful combination that can eliminate even the most stubborn fats. The liquid will have to be poured into the bag. You have to make sure that it is not too thick and that the bag does not pierce.
At this point, the bag must be hermetically sealed so that the liquid does not accidentally come out. Then, place the bag with the grid inside on a flat surface. The oven grill, in the bag, will have to rest for about two hours. If it is very dirty, extend the time, for example, let it rest 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 as good as new and ready to use again.
