Home lock maintenance method:

1. After most friends open the door, they will always push the door to the door frame, so that it can have the most intimate hug between it and the door, but this is not what the door wants, after we open the door, we should rotate the handle, so that the lock tongue of the door is retracted, and then the door frame is combined, in the release of the hand, in short, it is necessary to avoid the serious collision of the door lock, otherwise it will shorten its life.

2. When we open or close the door of the lock body, it will often rotate to it, and over time it will not be so flexible, therefore, we need to ensure that the rotating part of the lock body has lubricant, so that the friction of the lock body itself can be reduced, thereby increasing the service life of the lock itself, and in order to ensure the safety of the lock, we had better check whether the lock nail is loose.

3. In addition to the lock body we will often rotate, the lock cylinder is also a place that we often come into contact with, after a long time, the key will not be smooth in the process of unplugging, therefore, we need to add some items that can lubricate it for the lock cylinder, of course, the lock cylinder can never add lubricants or some oils.

Therefore, it is best to choose to add some graphite powder, which is the powder of the pencil lead, which can provide the best lubrication effect on the lock cylinder.
