How to clean door handles?

From door locks to window locks, from drawer locks to handle locks, we touch locks every day, but do we know how to install and maintain door locks? Next, I will tell you about the safe use and maintenance of hardware locks.

Appearance maintenance

1. During the renovation of the house, please seal the exposed parts of the door handle and panel of the lock with a plastic bag to prevent the surface treatment layer of the lock from being eroded by acidic or alkaline materials and gases during house decoration, resulting in spots and blisters. Even delamination phenomenon seriously affects the appearance quality of hardware locks. Some zinc alloy and copper hardware locks will notice “spots” after being installed on the door for a long time. This phenomenon does not belong to rust spots, but to oxidation. If this happens, just spray the surface with wax. Spots are removed with just one rub.

2. When using it safely under normal circumstances, if there are stains, it can be cleaned with a dry cloth. Do not use detergents and other chemicals to scrub, otherwise it will cause fading. Do not wipe the lock body and door handle with a damp cloth, it is easy to cause rust spots on some metal hardware locks, and the plating layer of alloy hardware locks is easy to be worn away, losing the beautiful suburban fruit.

The use of performance maintenance

1. When closing the door, it is best to hold the handle, screw the deadbolt into the lock body, and then release the door after closing the door. There is no need to force the door, otherwise the service life of the lock will be shortened.

2. When the main lock tongue or the safety lock tongue protrudes out of the door, do not collide violently to prevent the lock tongue and the door frame from being damaged.

3. Because the sealing strip installed between the door body and the door frame has an elastic effect, when the door is locked with the door handle or key, you can push the door or pull the door by hand to avoid the elastic force, and no strong rotation is required. The doorknob or key opens and closes the door to prevent the doorknob or key from breaking.

4. Always maintain the position of the lock body transmission with lubricant to make the transmission smooth and increase the service cycle. It is recommended to inspect once every six months or a year, and the screws must be tightened during inspection.

5. When the lock is in safe use, regularly smear a small amount of graphite powder or pencil powder into the hole of the lock cylinder to keep the key inserted and pulled out smoothly. However, other oils cannot be added as lubrication to avoid grease sticking to the spring sheet, resulting in the lock head not being able to rotate and thus not being able to be opened.

6. From time to time, check the mutual matching distance between the lock body and the locking plate, whether the height of the lock tongue and the locking plate hole is suitable for each other, and the mutual matching distance between the door and the door frame is preferably 1.5mm-2.5mm. If you notice any changes, adjust the exact position of the hinges or catch plates on the door. At the same time, it is necessary to pay attention to the cold shrinkage and thermal expansion caused by weather conditions to ensure that the gap between the door and the door frame, the lock body and the lock plate is reasonable, so that the hardware locks can be used safely and smoothly.
