1. Some zinc alloy and copper locks will have "long spots" if they are used for a long time. Don't think they are rusty, but they are oxidized. Just spray and rub the wax on the surface to remove the spots.


2. If the lock has been used for a long time, the key will not be inserted and removed smoothly. At this time, just apply a little graphite powder or pencil powder to ensure that the key can be inserted and removed smoothly.


3. The rotating part of the lock body should always be kept with lubricant to ensure smooth rotation. At the same time, it is recommended to check whether the fastening screws are loose in a half year cycle to ensure the fastening.


4. The lock shall not be exposed to rain for a long time, otherwise the small spring inside the lock will rust and become inflexible, and the rainwater falling contains nitric acid and nitrate, which will also corrode the lock.
