The blackening of Kangbach pot is a stain accumulated by residual food and oil, which has not penetrated into the pot. If you encounter such stubborn stains, it is recommended to fry eggs or cakes for 2-3 times to remove stubborn black stains. Or add some detergent or a small amount of vinegar and heat for 3-5 minutes, then gently clean with sponge or soft cloth, not with rough emery cloth or metal balls. It is suggested that after each frying, the stains on the inner surface of the pot should be cleaned up with a rag in time to prevent the accumulation of residual food and grease on the surface.
In order to solve the problem that the coating of the traditional non-stick pan is easy to fall off and may be harmful to health, Combach applied the etching process to the non-stick pan, created a new category-honeycomb pan, and applied for a German technical patent. Combach brought honeycomb pots into thousands of households and led the global pot industry into a major revolution.
