A cracked ceramic cooktop should be replaced as soon as possible to reduce the risk of permanent damage to the entire unit. The cooktop is designed to protect the burners beneath them.
Cleaning solutions and spills that penetrate the cracked cooktop may result in an electric shock. Ceramic cooktops require specialized care to keep them clean and damage free. Lemons, vinegar and baking soda are ideal green cleaning solutions. The cooktop should be cool before baking soda is applied directly to the cooktop, then wiped with a wet cloth to remove the stain. Cleaning is complete when the cooktop is polished with a clean, dry cloth.
