You’ll need a large garbage bag that can fit the oven rack and a dishwasher detergent tablet—or laundry detergent as a substitute.
Create a solution with the detergent and hot water in a bowl—ensure the water isn’t too hot to avoid damaging the bag. If necessary, help the tablet dissolve with a fork.
Add 3 or 4 tablespoons of baking soda to the solution to create a powerful degreasing agent. Pour this mixture into the bag, ensuring it’s not too thick and the bag remains intact.
Seal the bag securely to prevent leaks. Lay it flat with the rack inside, allowing the solution to work its magic on the grease and grime
