How to lubricate door hinges?
As a device that connects two objects and allows them to rotate relative to each other, the lubrication of door hinges is essential. To achieve the ideal lubrication effect, it is recommended to use lubricating oil or butter. Before applying lubricating oil, impurities such as rust and stains inside the door hinge should be cleaned first to ensure that the lubricating oil can fully work. In addition, sewing machine oil is also a good choice, especially when it is necessary to inject and turn the hinges of the revolving door. The lubricated door hinge will operate more smoothly and the abnormal noise problem will be solved.
In addition to lubricating oil, vaseline is also an excellent lubricant. It is not easy to get dusty, has good waterproof properties, and can maintain the lubrication effect for a long time after applying it once. Vaseline is divided into two types: medical and lubricating. Although medical vaseline is often used for skin repair, its lubricating properties are also excellent.
On the other hand, it should be noted that daily items such as access cards may interfere with certain equipment if they are not placed properly. For example, in a 2012 Shanghai Volkswagen Tiguan 1.8L sedan, the car could not be started because the access card was placed on the center console. The reason was that the access card interfered with the normal recognition of the key code by the car anti-theft system. This reminds us that items such as access cards should be properly kept and used to avoid unnecessary trouble.
