Every family has a door, how do you care?
Hardware is the soul of the entire inner door, including handles, locks, hinges, etc. They are small and important. The key to the service life of the inner door is the maintenance of the hardware.
Stainless steel handles and stainless steel hardware can be wiped with a brightener to add shine.
Moving parts such as hinges, hanging wheels, and casters may degrade performance due to the adhesion of dust during long-term exercise. One or two drops of lubricant can be kept smooth every six months or so.
When the lock cylinder is not flexible enough, a small amount of black powder can be scraped from the pencil lead and lightly blown into the lock hole. This is because the graphite component is a good solid lubricant. Never drop in the oil as it will make it easier to stick to the dust.
Pay special attention to the direction of the rotation of the handle and avoid the dead force. In particular, educate children not to hang on the door handle to sway, which is both dangerous and may cause damage to the inner door.
