The hardware components on Kitchen Cabinets should be kept clean, and the water stained areas should be dried in time to avoid rust. Kitchen Cabinets hinges and drawer slides should be oiled frequently to keep the opening and closing smooth. Do not hang things on the handle, especially some heavy or wet things. If the handle is loose, you can use a screwdriver to tighten the screws on the back of the door panel. When the door panel of Kitchen Cabinets is not neat or loose, the hinge can be adjusted. The hinges used in the market are generally adjustable in three dimensions.
