1. Listen to the sound: The material of the faucet is difficult to distinguish. A good faucet is cast copper as a whole, which sounds dull when beaten. If the sound is brittle, it must be stainless steel, and the quality will be a grade worse.

2. Look at the appearance: The surface chrome-plating process of a good faucet is very particular about it, and it usually takes a few steps to complete. The quality of a faucet depends on its brightness. The smoother and brighter the surface, the better the quality.

3. Turn the handle: When the faucet rotates the handle, there is no excessive gap between the faucet and the switch, and it is easy to open and close without slipping. But the poor quality faucet not only has a large gap, but also a large sense of obstruction.

4, identification mark: If it really can not distinguish, you can choose a more regular brand. Generally regular products have the brand logo of the manufacturer, and some non-formal products or some inferior products often only stick some paper labels, even without any marks, so be careful when buying.

 Reminder: You can use mild detergent (such as dishwashing detergent) to clean. Do not use cleaners containing ammonia, acid or bleach or use abrasive cleaners. Rinse and keep the entire surface dry. The surface-treated materials should be cleaned with original Windex lotion.
