Stubborn grease in the oven can be challenging to remove, but there are several effective methods you can try. Here are some of the best ways to tackle stubborn grease:

1. Baking Soda and Vinegar Paste:

   • Make a paste by mixing baking soda and water until it forms a thick consistency.
   • Spread the paste over the greasy areas in the oven, focusing on the most stubborn spots.
   • Spray or pour white vinegar over the baking soda paste. You'll hear a fizzing reaction, which helps loosen the grease.
   • Allow the paste to sit for several hours or overnight.
   • Use a scrubbing sponge or brush to scrub away the grease.
   • Wipe down the oven with a damp cloth to remove any residue.
