Rust is a chemical reaction that rusts when iron is left unused for a long time. Iron is susceptible to rust, not only because of its chemical activity, but also because of external conditions.

Moisture is one of the substances that makes iron rust easily. However, only water does not rust iron, and iron oxide is formed only when oxygen in the air is dissolved in water, and the oxygen reacts with iron in the presence of water.

Stuff, that's rust. Rust is a brownish-red substance, it is not as hard as iron, it can easily fall off, and after a piece of iron is completely rusted, the volume can expand by 8 times.

If the rust is not removed, the spongy rust is particularly easy to absorb water, and the iron will rust faster.

1. Use white vinegar. Vinegar reacts chemically with rust on metal, breaking it down. You can soak the metal in white vinegar for a few hours and then wipe off the rust.

2. Use lime and salt. Sprinkle salt over the rusty area, cover it thoroughly, and pour the lime juice on top. Try to use as much lime juice as you can get, and let it sit for 2 to 3 hours to wash off the layer.

3. Use the outer skin of the lime to wipe off the mixture, the peel of the lime should be enough to remove the rust layer and not further damage the metal.

4. Use potatoes and dishwashing detergent, cut the potatoes in half and cover the incision with dishwashing detergent, which will have a chemical reaction with the rust layer and make it easier to remove the rust layer. Place the potatoes on metal and let them sit for a few hours to remove the rust layer.

If it is rusty, it can be removed with white vinegar.

Put white vinegar on the rusty area, and then slowly soak it, and then wipe it off with a damp rag.

Rust, how to repair can use white vinegar to carry out a rust removal method, very simple, very practical, you can also use salt and add white vinegar, it works better.

First of all, you can use some special reagents to remove rust, or you can use manual grinding to remove rust.

The best way to remove rust is as follows:

1. Use white vinegar.

Vinegar reacts chemically with rust on metal, breaking it down. You can soak the metal in white vinegar for a few hours and then wipe off the rust. If the item is too big to be immersed in the white vinegar, you can pour a layer of white vinegar on top and let it condense.

You can also soak a rag in vinegar and wipe the metal.

You can try dipping aluminum foil in vinegar and using it as a brush to scrub away the rust. Compared to steel wool, aluminum foil is less worn, but still has the ability to remove rust. You can use regular vinegar and let the rusty metal soak in the vinegar for up to 24 hours before it is cleaned.

This method doesn't require much scrubbing.

2. Make a paste with baking soda.

Mix the baking soda and water together until the mixture is thick enough to apply to the metal. Give it some time to condense before scrubbing it off. You can try using a toothbrush to brush off the baking soda and rinse it with water.

You can dilute the baking soda with water to your liking, and there is no set mixing ratio.

3. Transform the rust layer.

Buy rust converts, they will stop the rust area on the metal from expanding. Rust converting agents are similar to spray paint and can also be used as a primer protective layer. While it prevents the rust layer from expanding, it may not be effective in completely removing the rust layer from the metal.

This method only works if you intend to paint on metal. It will also leave a rough texture under the lacquer coating, as you would have just covered the rust with a layer of lacquer.

Vinegar can remove rust. If there is rusty metal, you can pour some vinegar to soak it or wipe it directly with vinegar. Salt and lemon to rust.

Apply the salt to the rusty area, then squeeze the lemon juice on the salt and let it sit for a few hours before wiping it clean with a dry cloth. Baking soda to rust. Mix baking soda and water together to form a paste and spread evenly over the surface of the rusty item.

After 1-2 hours, you can start brushing with a brush. <

1. Vinegar can remove rust. Vinegar is a very common thing, if there is rusty metal, you can pour some vinegar to soak it or wipe it directly with vinegar.

2. Salt and lemon to rust. The same goes for lemon and vinegar. Apply the salt to the rusty area, then squeeze the lemon juice on the salt and let it sit for a few hours before wiping it clean with something.

3. Baking soda to remove rust. Mix baking soda and water together to make a paste, and then spread the baking soda paste evenly on the surface of the rusty item, remembering that it must be completely covered. After 1-2 hours, you can start brushing with a brush.

4. Diesel rust removal. If the tool is rusty, you can directly put the tool into the diesel and run for a while before taking it out to wipe.

5. Use potatoes and baking soda. Soak the potatoes in soda for a while, then take them out and place them on top of the rust layer for a few hours.

6. Use oxalic acid. Mix 25ml of oxalic acid with 250ml of warm water, soak the item for about 20 minutes, and then wash it off with a rag or brass brush to remove rust stains.

The rust can be removed by adding salt to the sliced shallots, sliced potatoes or radish skins, and rubbing the rust vigorously to remove the rust on the metal.

Rust is a chemical reaction between metal and oxygen, and in life, the most common is rust, which produces a brownish-red thing, which is not as hard as iron, but will absorb water more easily.

How to remove rust: You can first use a cut onion and the skin of a sliced potato or radish to add a little salt, and then rub the rust to remove the rust on the metal object.

The method of rust prevention: one is to smear the cut ginger slices on the metal object, the second is to wipe the metal object with the tea residue in a gauze bag, and the third is to soak the cleaned metal iron in the rice washing water, and then dry it.

What are the reasons why iron rusts easily.

People often lock valuables in safes. Gold has been lying in a safe for thousands of years, and it can be divided. Iron is not, even in the safe, it will be "stolen" - rusty.

None of the ancient ironware on display in the museum is not rusty; If you don't use the kitchen knife for a few months, you will be covered with rust, as the saying goes: "A quick knife does not need yellow rust". Iron, indeed, is prone to rust.

Every year, tens of millions of tons of steel in the world turn into rust.

Iron is susceptible to rust, not only because of its chemical activity, but also because of its external conditions.

Moisture is one of the conditions that makes iron rust easily. Chemists have proven that in absolutely waterless air, iron does not rust after a few years.

However, water alone does not rust iron, and it has been experimented with when a piece of iron is placed in a boiled, airtight bottle of distilled water, and iron does not rust.

Do you notice those water pipes along the river? They are often rustless at the top and stainless at the bottom, and it is only the section near the surface that rusts. It turns out that iron rusts only when the oxygen in the air is dissolved in the water.

The part close to the surface of the water is the closest to the air, and the water dissolves the most oxygen, so it is easy to rust. Carbon dioxide in the air dissolves in water, which can also rust iron. The composition of rust is very complex, mainly iron oxide, iron hydroxide and basic iron carbonate.

Rust is terrible, it's sleepy and soft, like a sponge, and when a piece of iron is completely rusted, it can swell eight times in size. This spongy rust is particularly easy to absorb water from the rotten chain, and naturally, the iron will rot faster. There are also many factors that make iron easy to rust, such as salt in water, the surface of iron products is not clean and rough, and iron is mixed with other metal ......And so on".

From the above analysis, we know that there are two main factors that cause iron rust: water and air.

In order to prevent the iron pot from rusting, it is OK to prevent these two things from clumping together and working.

Here's how.

1 Simpler.

After the iron pot has been used, hang it in a cool and ventilated place. Keep out of direct sunlight.

2 Those that have not been used for a long time.

Grease the iron pan with some oil.

Or fry fatty pork, pork rind and other things, then wash the pot with a soft rag, or shredded loofah, etc., and then hang it in a cool and ventilated place. Keep out of direct sunlight.

3 Usually pay attention.

Boil the soup in an iron pot and boil the water, then add some oil.

The spatula doesn't have to be too hard.

Avoid vigorously brushing the pot with hard objects such as steel wool balls.

As long as you follow the above practices, you can basically ensure that the iron pot does not rust.

Dip a little vinegar in a cloth and inspect the rusty area The principle is that acetic acid reacts with iron oxide (rust).

I'm like this when I touch the sandpaper! Or soak it in white wine {if your clasp is **of}

There is nothing more effective at removing rust than oxalic acid.

Please don't say that there is no oxalic acid in ordinary households, just go to the chemical store and buy a small bottle. In fact, liquid oxalic acid is now available in grocery stores, which is about 3 yuan a bottle, which is more convenient to use than crystalline oxalic acid bought in chemical stores. Only the branches are much lower in concentration, and they regret to imitate.

It is recommended to use toothpaste, detergent powder, etc., which have a certain friction force.
