I've been googling on how to clean green patina, or rather copper
sulfate oxidation from come metalic components. All I can find is how to
add it, not remove it! Evidently, this green substance is desirable for
certain applications, such as artwork. What can I use to remove it from
some copper hinges?


-Thanks

There's copper cleaner used to clean pots/pans. Bar Keeper's Friend
should also work. Both can be found in grocery and hardware stores.
Both are very mild abrasives.

Follow directions. Use old toothbrush for tight spots.

Navy used to use catsup for their copper galley steam tables. Because it is
acidic. Acid reduces (removes/reverses) oxides.

Abrasion works too

to prevent poatina from reoccuring, clean completely then spray with
clear acrylic.

always thought copper roofs looked bad once they aged........

new copper is pretty

dilute sulfuric acid - about 5% in water. Be careful, because it tickles
and puts holes in your clothes. Then spray with clear Krylon or some such.

The US Navy also used the powder mix for lemonade to clean the
unpainted steel floors. I don't know how it would work on copper.
This was back in the '50s, so I don't know if the current lemonade mix
is the same as then, either.

Well, which is it? Copper sulphate is blue. This, I remember. Copper oxide
is black, if memory serves.

Copper oxide and copper sulphate are not the same.

Have you tried copper polish? I've used very fine steel wool to
brighten brass, followed by clear
coat to protect. Worked great on long hinge on an upright piano.

Might scratch copper more than fine steel wool, methinks )
