Tie the bag tightly and let the grill sit for at least 90 minutes. If the grill is very dirty, it is recommended to leave it in the solution overnight.
After the allotted time, open the bag in the sink and, wearing gloves, clean the grill with a sponge. The dirt should be easy to remove this way.
Finally, rinse the grill under running water to remove any residue of the cleaning product.
By following these steps, you can clean your oven grill effectively and without much effort.
