Anything that is used only is not maintained, and things that are firm will gradually damage, so we must learn to maintain the things around us. Now let's take a look at the maintenance methods of doors and windows. There are four strokes in daily maintenance of doors and windows First, do not hang heavy objects on the door leaf and avoid sharp bumps and scratches. Do not use excessive force when opening or closing the door leaf. Second, do not open the door lock with wet hands or splash corrosive solvents onto the wooden door and door lock. Do not use excessive force when opening the door lock or turning the door lock handle. Frequently moving hardware such as hinges, door locks, etc., should be tightened immediately when loose. When the door lock is not working properly, you can lubricate the key hole with a proper amount of pencil core and other lubricants. Third, when wiping the glass, do not allow the cleaning agent or water to penetrate into the gap of the glass bead to avoid deformation of the bead. Do not use excessive force when wiping the glass to avoid damage to the glass. Be sure to ask a professional for repair after the glass is damaged. Fourth, when removing the stain on the surface of the wooden door (such as fingerprints), use a soft air to wipe it. Hard cloth is easy to scratch the surface. If the stain is too heavy, use a neutral detergent, toothpaste or furniture-specific cleaning agent. After decontamination, wipe it off immediately. Do not rub the corners of the wooden door frequently to avoid fading and damage of the facing material at the corners. When removing dust from the wooden door, use a vacuum cleaner to remove it when not using a soft cotton cloth. In order to maintain the gloss and service life of the wooden door, it should be cleaned and dusted regularly. The surface of the wooden decoration product can be used to maintain the surface.
