how to do if the lock is rusty
how to do if the lock is rusty.
1. Clean the lock with dry cloth.
drip soybean oil, sewing machine oil or sesame oil into the keyhole. At the same time, dip the key with a few drops of oil, insert it into the keyhole and slowly move it back and forth several times. If you feel smooth, you can open it by turning the key. After the lock is opened, timely use a few drops of oil, wipe it with dry cloth and maintain it.
2. If there is no oil temporarily, it can be replaced by soap or pencil lead debris, but the effect is slightly poor.
pour some kerosene into the lock hole, because it has the function of dissolving rust. There is also a kind of rust dissolving agent (or WD-40), which is the same extrusion spray (with a small tube, in order to avoid scattering) that is canned and used to kill mosquitoes. After dissolving rust, drop it out and then put some pencil foam into it. It’s easy to open as before.
be very careful when handling rusty articles. If you accidentally touch the clothes, you can use lemon to remove them: squeeze fresh lemon juice, drop a few drops of lemon juice on the rust stains, rub them with your hands, and repeat for several times until the rust stains are removed, and then wash them with soapy water. Or you can use vinegar cleaning (transparent vinegar, not colored vinegar, easy to pollute clothes): if you are worried that vinegar will make clothes fade, you can dilute the vinegar properly first. This method is not suitable for too bright clothes. The vinegar drops on the rust stains, slowly scrub, and finally rinse with soapy water.
precautions for the use of door lock. Often found that some users and friends, the door lock damage is often caused by improper use or maintenance. Some matters needing attention in door lock maintenance:
2. Don’t twist the key to open the door
sometimes, due to the gravity of the door leaf itself or the loose leaf of the door, the door leaf sinks, and the locking or opening is not smooth. At this time, it is often very difficult to open and lock the door with the key. At this time, don’t twist the key to avoid breaking the key and adding trouble.
correct solution: you should check the reason first. If the loose leaf causes the door leaf to sink, the loose leaf should be fixed tightly with screws. If the door frame is deformed or irrecoverable due to its reasons, start from the door frame and expand the lock tongue accordingly. In this way, the door lock can be opened and closed normally.
3. Don’t use lubricant casually
some friends often like to drip some lubricating oil into the lock hole when the door lock is astringent or tight. In this way, the whole body of the door lock may be smooth immediately, but because the oil is easy to stick to dust, it is easy to accumulate dust in the lock hole and form oil putty, This makes the door lock more prone to failure.
correct solution: sharpen some pencil fragments or some candle fragments, blow them into the lock cylinder through a small tube, then insert the key and turn it repeatedly for several times.
