The Best Method To Clean And Restore Copper Gutters

Hate cleaning your rain gutters? Well, join the queue. But as tempting as it might be, neglecting to clean your gutters does more harm than you think. That holds true even for copper gutters, which are known for their low maintenance and durability. Copper rain drains can survive well over 100 years, but only if you know how to clean your gutters to make them last. The cleaning methods for these water channels vary depending on whether you want to keep your copper's patina or if you prefer restoring its bright and shiny finish.

To clean patinated copper, start by ensuring your tools are plastic. Metal tools can scratch the copper surface and patina. Also, be sure to wear gloves while cleaning; not only to protect your hands but also to prevent the natural oils on your fingers from damaging the coating. Secure your ladder with a stand off bracket that will help it rest on the building, not the gutters. Then clear out any leaves or debris from the channel with a plastic trowel or your hands into a bucket or trash bag that'll be easy to carry down the ladder. If your downpipe is blocked, you can use a drainage rod to unclog it.

Next, use a soft-bristled brush and cleaning solution made from water and mild detergent to gently wipe the interior and exterior of your copper gutters. Never use harsh chemicals, like bleach, or abrasive brushes that can corrode your shiny copper finish. Finally, rinse the gutters with cold water, ensuring the downspouts are flowing freely.

If you're looking to keep your gutter's characteristic copper color, you'll still follow the steps above, but instead of a mild cleaning solution, you'll have to make a cleaning paste. A good tip for cleaning your gutter and restoring the polish is to work on them as soon as you notice they've developed a dull tone. This is because patina is harder to remove the longer it stays on a surface. To make the paste, thoroughly mix four cups each of vinegar, salt, and flour in a large plastic bucket. After cleaning out the dirt from the gutters, use a soft-bristled brush to apply the paste. Work in sections, rubbing the mixture in circular motions until the copper looks polished, then use a cloth to wipe the area. After you're done with one length of the gutter, rinse any leftover paste with water.

This paste works because the acetic acid in vinegar reacts with the oxides that make up a patina, essentially dissolving them. The salt in the mixture acts as an abrasive and may speed up the reaction. Plus, the flour helps create a paste-like consistency. Brasso Multi-Purpose Metal Polish can work as an alternative to this DIY paste, as well as an environment-friendly solution, like the HD Copper Cleaning Gel from Everbrite. Further, after you're done removing the tarnish from your gutters, prevent further discoloration by applying an antioxidant coating on them. Get one that offers UV protection and never use a lacquer coating, which stains the distinct copper color.
