The trumpet is rusty, what is the best way to remove the rust?

Just rub it with vinegar. 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 only when oxygen in the air is dissolved in water, the oxygen reacts with iron in an environment with water to form iron oxide, which is rust.

Commonly used methods to prevent iron rusting are:

1) Forming alloys to change the internal structure of iron For example, adding chromium, nickel and other metals to ordinary steel to make stainless steel greatly increases the rust resistance of steel products.

2) Covering the surface of iron products with a protective layer is a common and important way to prevent rust of iron products.

Rust in the trumpet will only appear in the sub-pipes, and there is really no way, which is a normal phenomenon. The surface should be rust-free. If it is silver-plated, it will only oxidize the surface.

It will be solved with a professional silver rubbing reagent. If it's too expensive, you can use toothpaste. However, this risk is still relatively large, and it is easy to accelerate surface oxidation.

Just rub it with vinegar, I often wipe it like this.

With dilute hydrochloric acid, the effect is absolutely good.

If you don't have the money to buy it

It's in your stomach, just find a way to make it

I don't know much either, you look it up on the Internet, and if not, you can ask the musical instrument store.

There is a professional rust remover to go to the supermarket and ask

There are several ways to remove rust:

1. Rust removal from shallots. Ingredients: green onions. Method: Cut the shallots and wipe the rusty knife vigorously to remove them. Suitable for rust that is not serious.

2. Wash rice water to remove rust. Ingredients: Rice washing water. Method: Immerse the iron spatula, iron spoon, kitchen knife and other cooking utensils in the relatively thick rice washing water, and scrub vigorously with a wire ball. This method also prevents rust.

3. Vinegar rust removal. Ingredients: vinegar.

Method: Copper products are rusty, scrub with vinegar, you can remove them, and then wash them with water. Method:

Aluminum products are rusty, prepare a basin of vinegar water, the proportion of vinegar and water is determined by different degrees, the heavier the rust and the larger the part, the amount of vinegar should be increased. The soaking time also depends on the degree of rust. Then take it out and it will be as clean as new.

Rust is an oxide. Rust is an oxide of iron that is formed when iron is oxidized with water dissolved. This means that if there is no water vapour in the air, or if there is no water at all, or if there is no dissolved oxygen in the water, rust will not form.

Oxide is a chemical compound (and must be pure, of course). It contains only two elements, one of which must be oxygen, and the other is called metal oxide if it is a metal element; If the other element is not a metallic element, it is called a non-metallic oxide.

Methods of rust removal: white vinegar to remove rust, lime to salt to remove rust, baking soda to remove rust, potatoes to add baking soda, use phosphoric acid or hydrochloric acid.

1. White vinegar to remove rust.

In fact, everyone is no stranger to white vinegar to remove rust, although white vinegar is just a more common condiment in life, but white vinegar is a very acidic item, so the effect of removing rust with white vinegar is excellent, and white vinegar itself is food, so the use of white vinegar to remove rust will not affect the normal use of kitchen knives, we only need to put the kitchen knife into white vinegar to soak for a few hours, and then wipe the rust with a rag, if it is not cleaned up, continue to soak, and the effect will be obvious after multiple soaking.

2. Add salt to lime to remove rust.

You only need to prepare some lime juice, first sprinkle salt on the rusty place of the iron products, and then pour the prepared lime juice on top to cover the surface of the iron products, and then wait for two or three hours, clean the salt and lime juice mixture on the surface, and then wipe the surface with the lime peel, which can effectively clean up some residual rust on the surface, of course, the lime can be replaced with lemon, and the effect is also very good.

3. Baking soda to remove rust.

Everyone will use baking soda for cleaning in daily life, in fact, the effect of baking soda to remove rust is also excellent, and it is cleaner, first of all, we need to dilute baking soda with water, try to dilute it into a paste, and then apply the paste of baking soda to the iron table, wait until the paste baking soda solidifies, wait for a period of time to clean it up, under normal circumstances, the rust has been cleaned up, if the effect is not obvious, then you need to replace other methods.

4. Add baking soda to the potatoes.

In fact, you can consider using baking soda and potatoes to coordinate, first cut the potatoes, and then apply a mixture of baking soda and water on the cut surface of the potatoes, and then put the cut surface of the potatoes after the rust, after a few hours, clean up the residue of the surface of the rising delay, the rust is generally cleaned up, if the effect is not obvious, you can cut off the used part of the potato, and then repeat the above method again, you can get rid of the remaining rust.

5. Scientific methods for using phosphoric acid or hydrochloric acid.

Phosphoric acid and hydrochloric acid are both common household items that are not only inexpensive but also very effective in removing rust. Phosphoric acid is actually a "rust converting agent" that converts iron oxide (rust) into iron phosphate, which becomes a black coating. Soak the rusty item in phosphoric acid, let it sit overnight, and then let it air dry, and scrape off the iron phosphate after the surface is air-dried.

The commonly used methods of rust removal are physical methods and chemical methods.

Physical rust removal: It is the use of tools or machinery to remove the rusty material on the surface of the metal, also known as polishing and grinding method. This method can only deal with the floating rust and visible rust on the metal surface, but for permeable rust and stubborn rust, physical rust removal is easy to cause residue and easy to return to rust quickly.

Moreover, for the labor cost is high, and the rust removal effect is not very ideal. The most important thing is that physical rust removal is easy to cause dust pollution and does not meet environmental protection requirements!

The best way to remove rust is chemical rust removal: chemical rust removal is to use rust remover to deal with the rust on the metal surface, and some can remove the rust while forming an anti-corrosion layer on the metal surface.

Chemical Rust Removal:

Acid rust remover: the common is strong acid (sulfuric acid, hydrochloric acid, nitric acid, etc.), but the disadvantages are greater, easy to cause excessive corrosion, and have a certain degree of harm to human safety.

Therefore, the current trend is organic acid rust remover, which is easy to meet environmental protection requirements, does not contain strong acid, is fast to remove rust, and is easy to use. ：

It is composed of a variety of surfactants, penetrants, accelerators, organic complexing agents, etc.

It does not produce "hydrogen embrittlement", does not require high-temperature baking and special cleaning, does not cause "excessive corrosion", and has almost no "weightlessness" even if it is soaked in environmental protection rust remover for a long time, which protects the original mechanical properties and processing properties of the steel.

Neutral rust remover: pH is neutral, which can remove floating rust, rust scale, and dissolved metal oxides.

The parts that need to be derusted can be removed without disassembling or grinding. There is no damage to copper, brass, aluminum, plastic, rubber, wood, vinyl and other materials.

Rust conversion agent: completely solve the problem of secondary rust after rust removal and before coating and the problem of secondary corrosion in the short term caused by incomplete rust removal.

After rust removal, the steel parts have a certain degree of rust resistance in a ventilated and dry place.

For the problem of rust, the most suitable method should be selected according to the requirements of rust removal and the nature of the workpiece to be removed!

Hello dear! Rust rapid rust removal is as follows: 1. White vinegar to remove rust.

White vinegar is also a more common condiment, and with a relatively strong acidic article, with it to remove rust effect is very good, as long as the item is put in the white vinegar soaked for a few hours, if not cleaned up to soak again, there is a clear effect after soaking. 2. Add salt to lime to remove rust. First of all, prepare the lime juice, take some salt and sprinkle it on the rusty place, then you can pour the prepared orange juice on it, wait for two to three hours, if my answer is helpful to you, please give a thumbs up (comment in the lower left corner), look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress.

If you feel that my answer is still satisfactory, you can click on my avatar for one-on-one consultation. Finally, I wish you good health and a good mood!

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 method of removing rust varies depending on the degree of rust and the material of the corroded surface. Here are some quick ways to remove rust: Use a wire brush or sandpaper:

Use a wire brush or sandpaper to brush or wipe off the rusted part until the rust layer is completely removed. Use chemicals: Using some chemicals can help remove rust quickly.

For example, acetic acid can be used to remove minor rust, while pickling solutions can be used to remove more severe rust. Use electrolysis: Electrolysis is the process of soaking corroded metal parts in an electrolyte and using an electric current to remove the rust.

This is a very effective method of removing rust, but it requires specialized equipment and skills. Use mechanical rust removal: For example, use mechanical equipment such as drills and grinding bits to cut, grind, and polish the rusted part until the rust layer is removed.

It should be noted that after the rust is removed, the metal parts should be treated with anti-corrosion in time to prevent secondary rust.
