Your dinner has been served, the table is cleared and the dishes are done. Before you dive into cleaning your glass-top stove, make sure the range is turned off and completely cooled. Spraying or applying any cleaning product it's hot can burn it right onto the glass, making an even tougher challenge for you. Fortunately, most glass-top stoves have a heat indicator light, so you don't risk burning your hand when checking to see if it's safe to clean. Once the light is off, it's safe to tackle whatever food stain awaits.
