What should I use to clean the stove?
When it's cool, spray it with distilled white vinegar and sprinkle baking soda over it. Moisten a towel in hot water and drape it over the baking soda and vinegar. After about 10 minutes, pick up the towel and use it to scrub the stove top clean, rinsing often. Spray more vinegar on the stove top and wipe it again.
