Drinking or consuming this infected water in any way can lead to Alzheimer’s or other intense health complications.

Will salt water corrode copper pipe?

Copper pipes are the most vulnerable to corrosion from exposure to salt water. The copper reacts with the salt, which can change the structure of the material. Galvanized steel and cast iron also react to salt water exposure, but they are a little more resistant than copper.

How do you remove green mold from copper pipes?

Wet a rag with acetone. Wipe the green section to remove the patina from the copper pipes. Acetone counteracts the patina and restores the copper coloring. Wear eye protection, gloves and a respirator to avoid acetone contact with skin and membranes.
