1. In many cases, the life of a thing depends on the small accessories. You can use a soft dry rag when the hinge is wiped, because the soft rag will not scratch the hinge and can better protect the protective layer on the surface of the hinge. Prevent rusting of the hinge.

2. In addition to the daily maintenance work, the most important thing is the quality of the hinge itself. If you are using a low-quality product, even if the daily maintenance is done well, it is easy to have a series of bad problems. For example, rust, unsmooth use, noise, and even deformation and breakage.
