Afterward, use a clean section of the damp washcloth to remove the excess salt before drying the pipe. If you don’t have the baking soda, white vinegar, and flour needed to create the paste, simply sprinkle salt onto a wet washcloth and scrub the green corrosion with the rag. It is also worth noting that salt on its own is an effective method for shining up copper and stripping oxidation. If you leave any moisture behind, the oxidation process will begin again, recreating the water and oxygen conditions that cause green corrosion. Be sure to dry off the pipe extremely well after rinsing, removing every drop of water. Then, use warm soapy water to clean the paste off of the pipe, allowing the alkaline nature of the soap to neutralize the acidic vinegar. Then, smear the paste over the oxidized area of the pipe. To create the mixture, combine equal amounts of baking soda, salt, white vinegar, and flour until it forms a paste.

This mixing of metal and oxygen produces copper oxide. Oxidation happens when copper is exposed to moisture and air.
