When the lock is tight and difficult to open, many people know to drop some lubricating oil into the lock, so that the lock can be opened smoothly. However, the oil is easy to stick to the dust, which will lead to the gradual accumulation of dust in the keyhole and the formation of oil putty, thus forming a vicious cycle.
