Due to the presence of trace amounts of carbonate in water, it is easy to form scale on the metal surface and cause corrosion on the surface of the faucet. Therefore, it is necessary to frequently use a soft cotton cloth or sponge with neutral soap water to wipe the surface of the faucet, and then dry the surface with a soft cloth. And clean the water outlet with a sieve to remove impurities and scale inside the sieve.
