Note: Do not wash the hot plate surface (when the temperature exceeds 40 ° C) because of excessive evaporation of water on the plate surface paint harmful! Of particular note is that, please use suitable detergent, a basic principle is: Be sure to use a neutral detergent! Do not use strong alkaline detergent such as potassium hydroxide, sodium hydroxide or sodium carbonate, strongly acidic detergents, abrasive detergents and the detergent soluble paint.
