What to do if the lock is rusted?
1. What to do if the lock is rusted?
The rust lock is mostly caused by being wet from rain or not being dried in time after contacting water. Here are some common practices.
1. Wipe the surface of the lock with a dry cloth.
Use soybean oil, sewing machine oil or sesame oil to drip into the keyhole, and dip a few drops of oil into the keyhole, insert it into the keyhole and slowly twitch it back and forth a few times. It feels smooth, and then twist the key and you can open it. After the lock is opened, use a few more drops of oil in time, wipe it with a dry cloth and take care of it.
2. If there is no oil temporarily, you can use soap or pencil core debris instead, but the effect is slightly worse.
Put some kerosene into the keyhole because it has the effect of dissolving rust. There is also a rust dissolver (or WD-40), which is a canned squeeze spray like a must-fight mosquito kill (with a thin tube to avoid scattering) sprayed into the keyhole. After dissolving rust, it will fall out and then inject some pencil foam, so that it will be as good as before.
Be especially careful when dealing with rusty items. If you accidentally dip it on your clothes, you can use the lemon removal method: take fresh lemon juice and rub it with a few drops of lemon juice on the rust stains. Repeat it several times until the rust stains are removed, and then wash it with soapy water. Or you can also use vinegar to clean (it is transparent and clean vinegar, not colored vinegar, which can easily contaminate clothing): If you are worried that vinegar will make the clothes fade, you can dilute the vinegar appropriately first. This method is not suitable for overly bright clothes. Scrub the vinegar on the rust stain slowly, and finally rinse it with soapy water. Notes on the use of door locks
1. Door lock maintenance
Door locks, such as high-load operating parts, will inevitably have a little failure if they have a long service life. It is often found that some users and friends have damaged door locks in their homes due to improper use or maintenance. Some things to pay attention to when maintaining door locks:
2. Do not forcefully twist the key to open the door
Sometimes, due to the gravity of the door leaf itself, or the door loose leaf, the door leaf sinks, causing the door lock or door opening to be unsmoothly. At this time, it is often very difficult to open and lock the door with a key. At this time, do not forcefully twist the key to avoid breaking it and causing trouble.
The correct solution: You should first check the reason. If the door leaf sinks due to loose loosens, the loose loosens should be fixed with screws. If the door frame is deformed or the reason for this is irrecoverable, you can start with the door frame and expand the lock tongue accordingly. In this way, the door lock opening and closing can return to normal and smooth flow.
3. Do not use lubricant casually
Some friends often like to drop some lubricant into the lock hole when the door lock becomes astringent or tight, so that the door lock may immediately become smooth, but because the oil is easy to stick to dust, dust will slowly accumulate in the lock hole, forming putty, which makes the door lock more likely to fail.
The correct solution: sharpen some pencil crushed powder or some candle crushed powder, blow it into the inside of the lock core through a thin tube, and then insert the key and rotate it repeatedly several times.
