Restoring copper gutters
-->Q. Aging copper gutters. I recently had 1/2 round copper gutters with round copper downspouts installed on my house. They are new manufactured and are bright brass in color. How long will it take for them to age naturally? Is there anything I can apply to them that will cause them to age quickly (turn brownish)? Please help.

Q. I have rain gutters made of copper that have turned brown. I would like to return them to their copper color. What should I use on them?

Q. I too have purchased a house with copper gutters and want to restore them. What if any chemical can I use.

A. Hi.
Brasso
⇦ on
eBay
or
Amazon [affil links] will bring up a nice warm color but the polishing is slow and probably too tedious for something as big as gutters. vinegar
⇦in bulk on
eBay
or
Amazon [affil links] and salt is very aggressive and fast, but will leave the copper raw and salmon colored, and must not be used on really fine detail. Compromises like Revere Copper Cleaner
⇦ on
eBay [affil links]
contain tarnish-dissolving mild acids, so they work quite fast, but are actual polishes that still leave a reasonably warm copper glow. After the polishing, though, you need brass lacquer

or the copper will tarnish very quickly. Good luck.
