How to deal with ancient money rust? Can you soak it in vinegar? Please help!

Throw it directly into pure water and soak it until the rust is no longer corroding. The time may take a year and a half, and it is almost the same as changing the water and raising fish every few days... I've tried it before and think it's the most effective, and I've also used wax seals for others; 502 envelopes and so on can't be sealed, and harmful rust will continue to corrode the money body.

Later, I saw in the book that the easiest way to isolate the air is blisters, so I tried it and thought it was okay, so I might as well try...

Rusty coins cannot be scraped off with scraping devices, and scientific methods are used for secondary use. Generally, coins are rusted and used in order according to the degree of rust: 1:

After soaking the coins in water for several hours, they are scrubbed with a copper or steel wire brush; 2: Soak the coins in vinegar; Two days, after taking it out, brush it as above; 3: Soak the coins in 10%-15% acetic acid solution for one or two days, and brush as above; 4：

Soak the coins in 10%-15% ammonia solution for one day, and scrub as above; 5: Apply diluted hydrochloric acid to the parts that need to be removed, put it in lime water to neutralize after brushing, and then take it out.

No way! Use only toothpaste.

OK. Physical rust removal method for ancient coins.

1. Vinegar soaking method. Wash the money, put it in a small dish and pour in a little vinegar until it submerges. After 24 hours, take it out, brush off the rust with a small brush, and then wash the vinegar with water after the money lines are clear, wipe it clean and dry, which is a relatively simple and commonly used method, which can deal with all kinds of floating rust, but the effect is often not ideal, and a lot of ancient money will appear yellow on the surface after vinegar, which affects the appearance.

2. Boiling water immersion method. Sometimes the old money will be covered with a layer of floating soil, but it will not always be washed off. In fact, this so-called floating soil is actually a kind of rust.

A mixture of earth and patina, which is an alkaline hard viscous float). For this kind of rust, we can first put the ancient coins in a bowl and pour boiling water at a temperature of 80-90 degrees into the bowl until the body of the coin is submerged.

After 5 minutes, take out the money, brush the money and the body with a small brush, and dry it in the shade. In the case of serious rust of ancient money, can also heat to boiling to make the rust fall off, through practice has proved that this method is very effective for removing rust, and has the great advantage of not damaging the coin pulp. Ancient coins along the grain, such as blurred patterns or rust into lumps, can also be separated in this way.

3. Dry brushing method. When the patina or rust is relatively shallow, you should try to avoid using chemical means such as vinegar bubbles, and you can use the dry brush method to clear the money lines. Here's how:

Choose a large oil painting and cut the brown hair on the tip of the pen until it is only close to the roots, (make sure that the roots are uniform) and use.

First put the ancient money to be brushed on the glass plate, fixed, if it is uneven, you can pad some cloth below, hold the root of the oil brush and brush evenly, pay attention to the force, otherwise the effect is not good, and wait for the floating rust to be brushed, and then wash it with water.

4. Washing method.

This method works well for iron money. Soak the coin in distilled water. Keep it at 98 degrees Celsius during the day and cool down at night. Replace the distilled water in a timely manner. Check the degree of rust removal until the rust is removed.

5. Mechanical method.

Instant use of a knife (preferably a straight knife), a brush (you can use a large oil brush and cut brown hair to only centimeters), pick a needle or dental tool to pick, pick, peel, brush and other methods to remove rust spots from money. Attention should be paid to the importance and moderation of rust removal in this method, but this method is not suitable for more precious ancient coins.

Before answering the question, let's talk about your **, the Kaiyuan Tongbao in ** is obviously soaked in oxalic acid, and the pulp is very unnatural. And there's a loophole. If you want to soak this coin in vinegar, you can try it as a practice.

It is okay to remove rust with vinegar. But as a last resort. If the money is obvious and there is not too much dirt, it is best not to soak it in vinegar.

If you must use vinegar, you must master the time, some only a few seconds, some take dozens of minutes or longer. Once overdone, ancient coins (especially those made of brass after the end of the Ming Dynasty) can easily turn red, and it takes a lot of effort to restore them to yellow.

In fact, there are many kinds of chemical rust removal, but most of them use acid, and vinegar is also an acid. It's not enough to just look at other people's experiences, you have to try it yourself. You might as well take the faulty ordinary ancient money like the one in the picture, try it a few more times in different ways and at different times, and slowly find out the experience.

Yes, but don't remove the particularly precious ones, in fact, it is not the rust that is valuable, and unprofessional rust removal will damage the coin.

It can be removed, except that it is worthless. It's worth a lot of rust.

Can be a common method of removing rust on coins.

1. Mechanical method. Remove coin rust with a knife (preferably a straight knife), a brush (you can use a large oil paintbrush and cut the brown hair of the tip to just a centimeter), a needle or a dental tool to pick, pick, peel and brush. The use of this method to remove rust should pay attention to the weight of the moderate, for the more precious ancient coins should not use this method.

2. Vinegar bubble method. Wash the money, put it in a small dish, and pour in a little vinegar until it is submerged. After 24 hours, take it out, brush off the rust with a small brush, and then wash the vinegar with water after the money lines are clear, and wipe it clean and dry.

However, many ancient coins will have yellow marks on the surface after soaking in vinegar, which affects the appearance.

3. Boiling water immersion method. Ancient coins are sometimes covered with a layer of rust that cannot be washed off, so you can put them in a bowl and pour boiling water at a temperature of 80 to 90 until the coin is submerged. After 5 minutes, take out the money, brush the money pattern and body with a small brush, and dry it in the shade.

In the case of ancient money with serious rust, the water can also be heated to boiling to make the rust fall off.

4. Dry brushing method. When the patina or rust is relatively shallow, you should try to avoid using chemical means such as vinegar foaming, and you can use the dry brush method to make the money lines clear. The specific method is to choose a large oil paintbrush, cut the brown hair on the tip of the pen to a centimeter from the root, and then use.

First put the ancient money to be brushed on the glass plate, fix it, hold the root of the oil brush and brush it evenly, pay attention to the force, otherwise the effect is not good, and then wash it with water.

5. Heating method. This method is mainly for iron coins with shallow corrosion. The main component of rust is ferrous oxide, its molecular structure is relatively loose, and the firmness of adsorption with iron money is far less than that of copper coin, so the principle of thermal expansion and cold contraction can make part of the rust of iron money fall off.

However, when using this method, it is necessary to pay attention to the addition of a bearing vessel (such as a metal container such as a pot), and it is also advisable to add some water. Secondly, the heating time should not be too long, generally after heating for three or four minutes, take it out and cover it with a cold wet towel, and the rust will naturally fall off. Choose the heating method to remove rust, the object should be the iron money with good iron quality and relatively shallow corrosion, and the iron money with serious rust and the body of the money has been very fragile with the heating method to remove rust, otherwise the already very fragile money will not be able to withstand the high temperature and be fragmented, and the body will be broken.
