No need to scrub, just put the grate in a bag and it will be as good as new again

A huge garbage bag, or similar, is the first item you’ll need. The oven rack ought to fit snugly within the bag. You are under no obligation to purchase one if you do not already own one. Substitute the tablet with ordinary washing detergent; that’s all.

A bowl is the next item you’ll need for placing the detergent or tablet. To ensure a thorough dissolution, add hot water to the bowl before pouring it straight over the tablet. It goes without saying that the water shouldn’t be boiling or else it can burst the bag. Use a fork to hasten the dissolving process if the tablet is still partially intact.

Stir in three or four teaspoons of baking powder. By combining these ingredients, you may make a powerful combination that can dissolve even the most entrenched grease. Transfer the liquid to the bag. To avoid puncturing the bag, make sure it is not too thick.

Oven Now is the time to seal the bag securely to prevent any unintentional leakage of the liquid. After that, set the rack-containing bag on a level surface. Allow the oven grill to rest in the bag for about two hours. You may need to give it more time—maybe even overnight—if it’s very filthy.

Take the oven rack out of the bag and give it a quick rinse under the water when the allotted time has passed. You won’t have to scrub. After that, it will be completely usable again, just like new.
