This first step is all pretreating; no cleaning. Pour Dawn on a dry paper towel and rub it on the effected area. Make sure the entire area is well coated with detergent. Allow to sit for 15 minutes.
Next, heat your Magic Eraser by running it under hot water. Squeeze out excess water. Now, begin rubbing the area you treated earlier. You will have to rinse your sponge often using hot water. When you've cleaned the entire area of grease, wipe down with a dry cloth.
Viola, you're done.
