If you have a glass stove top you know it can be difficult to clean stains from it. Instead of the pricey commercial cleaners, you can make one yourself by making a paste using 3 tablespoons of baking soda and 1 tablespoon of water. Spread this over the stained area. Lay a warm, damp dish towel on top of this and let sit for a half an hour. Then wipe off completely. The baking soda is mildly abrasive and will clean the grease and grime.
