Over time, copper pipes lose their shine and begin to tarnish, but they can be restored to their former glory if you know how. This guide will show you different techniques for ensuring your copper pipes can gleam again.
Why do copper pipes tarnish?
It is normal for copper pipes to become discoloured because of oxidation – the process of being exposed to moisture and air which causes a chemical reaction. This leads to the formation of a copper oxide layer which turns the pipe green, in what’s known as patina. Although patina is not harmful to your health, it doesn’t look nice and can sometimes be a sign of problems such as leaks in the pipe.
Natural cleaning
If you don’t like using harsh chemicals, you can use the housewife’s favourite home cleaning solution of baking soda and vinegar, applying it to any corroded areas with a soft cloth. Another option is lemon juice and salt, as the acid in the lemon can help break down the oxidation. Other home cleaners say they’ve used brown sauce and ketchup, which are also acidic and have the same effect.
Professional products
In the old days of the aristocracy relying on household staff to clean, butlers would clean copper pots with Solvol Autosol. This is a metal polish which is mildly abrasive and is not the only product available.
Materials
Non-scratch abrasive pads are good for removing tarnish without scratching the copper, but if the corrosion is particularly bad, you can use steel wool in a fine grade. Unfortunately, if the discoloration is severe, you may have to consider replacing the pipe, or at least that section of it, to prevent further damage or the pipe failing. If you are looking for a new copper pipe, there are several options, such as copper pipe from Watkins and Powis, who have a range of lengths and widths available.
Safety first
As with all cleaning involving chemicals, you should always wear protective gloves to protect your skin from irritation and keep the area you’re working in well ventilated.
