Maintenance of composite doors

1. Do not hang too heavy items on the door leaf or avoid sharp objects bumping, scratching when opening or closing the door leaf. Do not use too much force and do not hit the door. 

 2. Do not open the door lock with wet hands, or splash corrosive solvent on the door and door lock. Do not use too much force when opening the door lock or turning the door lock handle. Hinges, door locks and other hardware accessories that are frequently moved should be tightened immediately when they are loose. When the door lock is not opened, you can add an appropriate amount of pencil foam and other lubricants to the keyhole for lubrication.   

3. When wiping the glass, do not let the cleaning agent or water penetrate into the gap of the glass strip to prevent the strip from deforming. Do not use too much force when wiping the glass to avoid damage to the person. If there is a major bump after the glass is damaged, please ask a professional to repair it. 

 4. When removing stains on the door surface (such as handprints), you can use air to wet it and wipe it with a soft cloth. Hard cloth can easily scratch the surface. If the stain is too heavy, use neutral cleaning agents, toothpaste or furniture-specific cleaning agents. After decontamination, wipe them clean immediately. Do not rub frequently at the edges and corners of the door to avoid fading and breaking of the finishing materials at the edges and corners. When removing dust from the door and erasing without using a soft cotton cloth, a vacuum cleaner can be used to remove it. In order to maintain the gloss and service life of the door surface, cleaning and dust removal should be carried out regularly. The surface of the wooden decoration products can be maintained using a special maintenance liquid. 

 5. In spring and winter, the indoor ventilation should be maintained to keep the door in a normal temperature and humidity environment, and prevent the door from deforming due to excessive humidity and temperature difference, and metal accessories will have corrosion, edge sealing, and decorative materials. When using electric heating or other heating equipment in winter, stay away from the door to avoid deforming it due to heat.   

6. When painting the walls, cover the door to avoid painting the paint to peel off and fade the door finish material, which will affect the overall beauty. More
