Copper casting is widely used in our daily life, but do you know the maintenance of copper casting? This article will introduce the repair method of copper casting.

Maintenance of cast copper parts:

1. The room where copper crafts are stored must be dry, dust-free, without air pollution, and the relative humidity should be 50.

2. All pollutants must be removed before storage, preferably chemical protection. Do not wear cotton gloves when touching crafts and handicrafts that are thick with grease and grease. Do not touch with sweaty hands or wrap in greased paper or boxes.

3. Use soft wool cloth, soft brush and soft hair dust to remove the dust in copper crafts.

4. If water must be washed with distilled water, distilled water can also be heated with neutral soap. Do not use ammonium hydroxide, acid and white powder, gauze, etc. If there is a large area of cleaning, it can be cleaned by professionals.

5. Clean casting copper crafts can be coated with chemical protective agents or heated paraffin wax. The modern method is to apply silicone seals to protect against harmful gases and moisture.

6. To prevent mechanical damage to the object, do not stack on top of each other. It's best to put each piece of art in a satin box.

7. Often observe the changes of copper crafts, once the symptoms of copper poisoning, should be dealt with in time. This method can be washed with sodium bicarbonate (5% sodium bicarbonate) until there are no chloride ions.

The above is the maintenance of copper casting. I hope it will be helpful to you.
