👉 The door fluid, often referred to as a door lubricant or dry lubricant, is a specialized product designed to reduce friction between the hinges and other moving parts of a door. It typically consists of a blend of silicone-based or graphite powders, which create a protective layer that prevents metal-to-metal contact and wear. This lubricant is applied to the hinges and can also be used on other components like door handles and latches to ensure smooth operation and extend the lifespan of the door mechanism. By minimizing friction, door fluid helps doors open and close effortlessly, reducing noise and preventing rust or corrosion.
