To effectively remove green corrosion from copper pipes, you can create a paste using equal parts of salt, flour, and white vinegar. Apply the paste to the corroded areas and let it sit for about an hour. Then, scrub the area with a soft brush or cloth and rinse thoroughly with water. Repeat the process if necessary until the corrosion is removed.

What is the long term impact of water and oxygen on copper?
Corrosion or the coper item resulting in holes or structurally weakened copper. It turns very green; like the statue of liberty which is also made of copper. It should be cleaned with acid to remove corrosion.
What metal turns green and why?
Copper is a metal that turns green when exposed to air and moisture due to a chemical reaction forming a patina. This patina is a protective layer that forms on the surface of the copper, acting as a barrier against further corrosion.
What causes the green sludge inside your copper pipe at the connection site to your hot water tank?
the green sludge is the result of copper pipe corrosion. it's a copper oxide
Why is there a green spot on a potato after electricity has been passed?
Corrosion of copper electrode generates copper salts (which are blue/green) that then diffuse into the flesh of the potato. Don't eat them, copper salts are toxic!!!
How can I effectively remove green tarnish from copper surfaces?
To effectively remove green tarnish from copper surfaces, you can create a paste using equal parts of vinegar, salt, and flour. Apply the paste to the tarnished areas and let it sit for about an hour. Then, scrub the surface with a soft cloth or brush and rinse with water. Repeat the process if necessary until the tarnish is removed.
What are some examples of corrosion?
Iron and steel rusting is an example of corrosion. Copper pitting or the green patina one sees on copper roofs are also examples of corrosion. Stress Cracking is also considered an example of corrosion.
Is green corrosion on copper pipes dangerous?
Green corrosion on copper pipes, known as verdigris, is not typically dangerous to health. However, it can indicate potential issues with the pipes, such as leaks or degradation, which may lead to water damage or plumbing problems. It is important to address the underlying cause of the corrosion to prevent further damage to the pipes.
What is the value of a copper penny from 1920 that is in good condition but about 85 to 93 percent turning green?
The value of a copper penny from 1920 in good condition with some green corrosion (85-93% turning green) would likely be around 5 to 10 cents for its copper content. The coin's numismatic value might be lower due to the corrosion, unless it is a rare or highly sought-after variety.
What are the best methods for preventing corrosion on a green copper pipe?
The best methods for preventing corrosion on a green copper pipe include applying a protective coating, using dielectric unions to separate different metals, ensuring proper insulation, and maintaining a consistent pH level in the water. Regular inspections and maintenance can also help prevent corrosion.
Why does copper tarnish and turn green?
Copper tarnishes and turns green due to a chemical reaction with oxygen and sulfur compounds in the air, forming copper oxide and copper sulfate. These compounds create a greenish layer called patina on the surface of the copper, which acts as a protective barrier against further corrosion.
What are the common causes and solutions for green corrosion on copper pipes?
Common causes of green corrosion on copper pipes include exposure to moisture, high levels of oxygen, and acidic substances. Solutions to prevent green corrosion include proper insulation to reduce moisture exposure, using corrosion-resistant coatings, and maintaining a balanced pH level in the water supply. Regular inspections and maintenance can also help identify and address any potential issues early on.
What is causing the copper in your attic to turn green?
If your attic doesn't have any leaks, then the patina (green color) is most likely formed by the reaction between the copper and carbon dioxide in the air, forming copper carbonate. This patina, called verdigris, protects the copper underneath from corrosion.
