There is much corrosion, especially surface corrosion. It does not seem like much, but then I remembered that the green oxidation form comes much later, after the dark form, and most metals are getting darker, except water. This is reinforced by the fact that copper is a extremely good metal for corrosive resistant products, in pipes, it cost 3-4 times as much than steel pipes. The corroded water for clorox is dark dark green, almost none for drano, dark blue for ammonia, none for water, light green for salt water, and none for sulfuric acid
