After each use of the range hood, it is recommended to wipe the surface of the main unit with a soft cloth. To protect the coating, use a mild detergent along with a soft cloth. Avoid using toothpaste, hard-bristle brushes, or other abrasive tools. Do not use corrosive chemical agents such as gasoline or alcohol, or cleaning products with abrasive properties (e.g. toothpaste or dishwashing liquid), as they may damage the surface of the unit.
