Sihaiwang: lock is a very common tool in our life. Now most locks are made of iron. They are exposed to the air for a long time, and are easy to be oxidized and rusted to form rust. What should we do if the lock is rusty? How to remove the rust when the lock is rusty? Now I'll teach you some tips on rust removal and rust prevention. Let's have a look.
Lock rust is mostly caused by rain or contact with water and not dried or dried in time. Here are some common practices.
Wipe the outside of the lock with a dry cloth.
Drip soybean oil, sewing oil or sesame oil into the keyhole, dip the key with a few drops of oil, insert it into the keyhole and slowly twitch it back and forth for several times. It feels smooth, and then turn the key to open it.
After the lock is opened, use a few drops of oil in time, wipe it with a dry cloth and maintain it. If you want insurance, next time you don't want trouble, you should change the lock in time. Because this way is not to try lark.
If there is no oil temporarily, it can be replaced with soap or pencil lead debris, but the effect is slightly poor.
Pour some kerosene into the lock eye, because it has the function of dissolving rust. There is also a kind of rust containing agent. It's the same squeeze spray (with a thin tube, to avoid scattering) that can be packed and used to kill mosquitoes. Spray it into the lock eye. After dissolving rust, drop it out and then put some pencil foam into it, and it will open as before.
Special care shall be taken when handling rusty articles. If the rusty articles are accidentally touched on the clothes, lemon can be used to remove them: extract fresh lemon juice, drop a few drops of lemon juice on the rusty stains, rub them with hand, repeat several times until the rusty stains are removed, and then wash them with soap water. Or you can use vinegar to clean (transparent vinegar, rather than colored vinegar, which is easy to contaminate clothes): if you are worried that vinegar will make clothes fade, you can first dilute the vinegar properly. This method is not suitable for too bright clothes. Drip vinegar on the rust stain and wash it slowly. Finally, wash it with soapy water.

It is often found that some users and friends, the damage of the door lock at home is often caused by improper use or maintenance. Some precautions for door lock maintenance:
Don't twist the key to open the door
In some cases, due to the gravity of the door leaf itself, or the cause of the door leaf, the door leaf sinks, resulting in the phenomenon that the door is not locked or opened smoothly. At this time, it is very difficult to open and lock the door with the key. At this time, do not twist the key forcibly to avoid breaking the key and increasing trouble.
The right solution: look at the reason first. If the loose leaf causes the door leaf to sink, fix the loose leaf with screws. If the door frame is deformed or the cause is irrecoverable, start with the door frame and expand the locking tongue accordingly, so that the door can be opened and closed normally and smoothly.
Do not use lubricant casually
Some friends often like to drip some lubricating oil into the lock eye when the door lock is astringent or tight. In this way, the whole lock body may be smooth immediately. However, because the oil is easy to stick to dust, it will be easy to accumulate dust in the lock eye later, and form oil putty, which in turn makes the lock more prone to failure.
Correct solution: sharpen some pencil fragments or some candle fragments, blow them into the lock cylinder through a thin tube, and then insert the key and turn it repeatedly.

Rust removal and rust prevention
Rust is a chemical reaction. When iron is put for a long time, it will rust. Iron is easy to rust. Water is one of the substances that make iron easy to rust. However, water alone will not rust iron. Only when the oxygen in the air dissolves in the water, oxygen reacts with iron in the water environment, it will generate something called iron oxide, which is called rust. Rust is a kind of brownish red material, it is not as hard as iron, and it is easy to fall off. After a piece of iron is completely rusted, its volume can swell 8 times. If the rust is not removed, the sponge like rust is particularly easy to absorb water, and the iron will rot faster.
To remove rust, you can use various tools to shovel it off, or you can soak it in an acid solution to dissolve it. After removing the rust, the surface of the iron must be treated, coated with a layer of lead, and then painted; or plated with other metals that are not easy to rust. A more thorough way is to add some other metals to iron to make a stainless alloy. The familiar stainless steel is an alloy made by adding a little nickel and chromium to the steel.
The common methods to prevent iron from rusting are as follows:
(1) The composition of alloy to change the internal structure of iron, such as adding chromium, nickel and other metals into ordinary steel to make stainless steel, will greatly increase the rust resistance of steel products.
(2) Covering the surface of iron products with protective layer is a common and important method to prevent the rust of iron products. According to the composition of the protective layer, it can be divided into the following types:
a. Apply mineral oil, paint or firing enamel, spray plastic on the surface of iron products, such as: car, bucket, etc. often apply paint; machine often apply mineral oil, etc.
b. The surface of iron and steel is plated with a layer of metal, such as zinc, tin, chromium, nickel, etc., which is not easy to rust. These metal surfaces can form a dense oxide film, so as to prevent iron products from contacting with water, air and other substances and rusting.
c. A dense and stable oxide film is formed on the surface of iron products by chemical method to prevent rust of iron products.
(3) Keeping the surface of iron products clean and dry is also a good way to prevent iron products from rusting.
