I posted this photo on facebook the other day and people said they wanted me to explain the "how to" about it. I cleaned the glass on my oven with just rubbing alcohol and baking soda. Sprinkle the baking soda over the glass. Put the rubbing alcohol in a spray bottle and spray it right on the baking soda. I used a sparkle sponge to clean it - so it wouldn't scratch the glass. The greasy build up came right off! Now that was easy!
