Default green corrosion on bronze/brass seacocks

what is the best chemical or way to clean the green corrosion off of bronze seacocks and valves ? tried spraying them with salt away but it didn't remove any of the green corrosion. once removed does anyone spray these components with corrosion x or some other chemical to prevent more corrosion?

The green stuff is copper sulphate. Use a metal polish formulated for brass on a soft damp cloth then polish off with a clean soft cloth. They can be sealed with various clear products but if you have to clean em now & again at least you will be able to check their condition. Plus the sealer will need to be redone.

On reflection, it is probably copper acetate but the fix remains the same.

Peter,
Does the copper sulfate appear on bronze as well as copper products when exposed to salt.

It's romantically called "verdigris" and doesn't cause any particular harm. If you want to minimize your efforts, just use a small stiff stainless steel wire brush on it.

You can rub bronze valves with vasaline and the green will not come back.

Bronze is an alloy of copper & tin plus a few extras & is suitable for marine use. Brass is an alloy of copper & zinc with additives. Both are susceptible to tarnishing. It is only cosmetic.

In fact the green stuff is a natural protective barrier, if you don't mind the cosmetic apperaance.
