How to wipe the ocean clean, how to clean the ocean discoloration

Oceans belong to silver coins.

Generally, gold and silver coins can be made of weak acid.

Weak alkali treatment, others are not recommended. Because although acid and alkali can temporarily clean the surface, the corrosion of copper, nickel, aluminum and other materials will look very ugly in the future.

The most commonly used dish soap is dish soap.

Or wash with soap, or put in boiling water and boil for 5-10 minutes, but sometimes the effect is not obvious. This type of method is less damaging to the coin itself.

Darkened, darkened, and dirty coins are soaked in boiling water, then squeezed some toothpaste on the surface of the coin, and then scrubbed with a soft cloth, repeating several times.

If the surface of the coin has been oxidized and the dirt is more serious, you can use a coin brush to rub it to remove the dirt and oxide layer and restore its original appearance.

All the quality and modern coins, the surface of the coin only has a slight oxide layer, dust, and hand sweat.

Fingerprints, etc., can be wiped several times with an eraser, and the surface will be as bright as new.

Coins with serious dirt and no longer visible patterns cannot be removed by the above methods, so dilute hydrochloric acid can be used first.

Soak for a few minutes, then soak in alkaline water for a few minutes, then wash with water, and finally brush a few times with a coin brush.

If the quality is different, the issuance age is old, the surface of the coin has been oxidized and corroded, you can first soak the coin (except aluminum coins) in vinegar for a few minutes, wash it with water after taking it out, and then rub it with a coin brush (glass fiber system) several times, and you can also remove impurities and dirt on its surface.

The method of cleaning a silver coin depends first and foremost on the degree of oxidation of the silver coin and its fineness. Oxides formed on the surface of silver alloys with high silver content have different characteristics than oxides formed on the surface of silver alloys with low silver content.

If a coin with a high silver content is left underground for a long time, or if it is subjected to other adverse factors, a thick layer of oxide will form on its surface, and the coin should be soaked in an aqueous ammonia solution for 1 hour (composition: 90% water and 10% concentrated ammonia). If there is no aqueous ammonia solution, sodium carbonate solution (30 grams of edible soda ash dissolved in 100 grams of water) can also be prepared instead.

The coin is placed in the solution for a few hours until the oxide is completely dissolved.

If the high silver content of the silver coin is only slightly oxidized, then it is best to clean it with an ammonia solution with a sodium carbonate solution and toothpaste to make a paste. This paste should be soft to the touch and free of fine hard particles. This is done by gently applying it to the surface of the coin with your fingers or with a soft brush, and when the oxide has dissolved, rinse it off with clean water.

Low-silver silver coins with copper as a intermediate alloy turn green when heavily oxidized. To wash such coins, it is best to wash them with a solution of 5% dilute sulfuric acid. When the rust layer is dissolved and receded, it is cleaned by cleaning the silver coins with high silver content.

However, if the oxide on the surface of the coin is homogeneous, it is not necessary to clean it off.

Tips: Generally, coins should not be cleaned, because of dust, sweat, the hands of the player, or buried in the soil, long-term friction, and even the passage of rays in the air, layer by layer, the gradual formation of the surface shell, called pulp. The pulp is also known as "black lacquer ancient", it is smooth and gratifying, and the light is quiet, telling you that this thing has an age, revealing a warm old atmosphere.

That's exactly the contrast with the dazzling "thief light", impetuous tone, and dry texture of the new product that has just come out. Pulp is not only the best protection for coins, but also the best material for coin identification! If it is dirty things that get on later, the best way is to boil it in boiling water, and the real pulp cannot be boiled.

This is also a good way to identify the authenticity of the toning!

Simple treatment can be electroplating.

The method is as follows: 1. Go to a nearby Chinese medicine pharmacy or pharmacy to buy a pack of alum;

2. Then boil your ocean in water at the ratio of water 10:alum 1 (the water must be boiling);

3. Take out the ocean and put it in cold water with a soft brush (such as a toothbrush) and dip it with toothpaste or laundry cream or salad to clean;

4. Dry it with a hair dryer and wipe it with suede to make it look as good as new.

It's not worth anything when it's washed! A Tibetan friend got a bronze mirror! Seeing the rust on it, I found the gauze and polished it, and came to the gate of Huayu for identification, and got married is an expert who gave such a sentence, your salary is too expensive, it was originally worth 200,000, and you wiped 100,000 yuan like this, the salary is too expensive!
