Believe it or not, I have used toothpaste to clean my stove top! It is not abrasive to scratch and works really good. Also a paste of baking soda can be used. I always save old toothbrushes for cleaning stuff like this because you can really get into the cracks. I also use baking soda and boiling water or baking soda and vinegar to unclog drains in my bathtub and sinks. .
Thank goodness for Heloise!
