Blue color on bronze seacock

[hd002e]

I noticed a pretty strong hue on my head discharge seacock that is mounted on the floor at the head. I am color blind but pretty sure it is a blue color. Did I get the dreaded bronze disease or is this something else? How do I keep things under check? What do I do?

That is really the normal bronze "green" tarnish that they get over time. Real worry happens when the bronze takes on a "pink" colour.

I really appreciate this. As a colorblind solo sailor I was having a hard time. Thank you ��

That is "verdigris" often referred to as "patina". It is technically a form of corrosion but is so mild it poses no threat to the metal, in fact it actually forms a protective coating to a degree.

If it bothers you, you can remove it with a brush and some baking soda and lemon juice.

PS. The "pink" colour referred to happens to brass, not bronze and is due to dezincification caused by galvanic corrosion.
Brass has a much higher zinc content than bronze.
