Do you have copper pipes that are starting to show signs of damage, corrosion or build-up? If so, it is important to clean them regularly to prevent damage to the pipes.
Since it’s not an everyday activity, however, you may be wondering how to clean copper pipes. In this blog post, we’ll give you a step-by-step guide using various household ingredients you probably already own.
Let’s begin!
Why should copper pipes be cleaned?
While newer homes tend to use PVC piping more often, copper piping is prevalent in older homes. Plus, they’re still a popular choice for many homeowners.
One of the reasons why copper pipes are favored is that they are less susceptible to leaks. They can last up to 70 to 80 yearswhile PVC tends to last only 25 to 50 years.
However, copper piping can develop problems over time if not properly maintained. One of the most common problems is staining. This is caused by a reaction between copper and oxygen in the air.
Tarnish is not harmful and can be cleaned off. However, if left too long, it can lead to corrosion. This happens when the copper pipe starts to break down and develop holes.
Another problem that can occur is build-up. This can be caused by a number of things, including calcium, lime and other minerals in the water.
Copper pipes are susceptible to damage, corrosion and build-up for a few reasons. First, copper is a reactive metal, which means it reacts with other elements in air and water. Second, copper pipes are often located in wet or damp areas, which can accelerate the deterioration process.
That’s why it’s important to clean your copper pipes regularly using one of the methods below.
How to clean copper pipes
Now that we’ve gone over some of the reasons why copper pipes need to be cleaned, let’s take a look at how to do it.
Method 1: Clean copper pipe with vinegar and salt cleaning solution
One of the simplest ways to clean copper pipes is to use a solution of vinegar and salt. Vinegar is one of them magical ingredients which can be used to clean (as well as sanitize) a variety of surfaces and is therefore also excellent for copper pipes.
The acidic nature of vinegar helps break down tarnish, corrosion, and build-up. And don’t sweat it if you don’t have vinegar. You can use lemon juice instead.
Salt is also a good cleaning agent and will help clean stubborn dirt or grime.
To make this solution, all you need is white vinegar, salt, and a clean cloth or sponge.
Start by mixing equal parts vinegar, salt, and all-purpose flour in a bowl. This will create a paste. Next, apply the mixture to the copper pipes using a cloth or sponge.
Scrub it well, paying particular attention to areas that are stained or corroded. Then let it sit for 10 to 15 minutes.
After rubbing the detergent into the copper pipes, rinse them with warm water. Make sure you remove all the cleaning agent so it doesn’t cause damage.
Method 2: Clean the copper pipe with vinegar only
If you don’t have salt on hand, you can still use vinegar to clean copper pipes. However, you will need a lot of vinegar for this method.
For cleaning copper pipes with just vinegar, simply place the copper pipes in a small tub and pour the vinegar over the pipes. Again, let the vinegar soak for 10 to 15 minutes before pulling the pipes out of the tub and rinsing them with warm water.
Dry the outside of the tubes with a soft cloth and then let them rise so that the moisture inside drains and dries.
Method 3: Clean the copper pipe with ketchup
Yes, you read that right! Ketchup it can actually be used to clean copper pipes, just like lemon juice or vinegar. The acid in ketchup is effective at removing stains, corrosion and deposits.
To use ketchup, apply a generous amount of the condiment to a clean cloth. Rub the ketchup into the copper pipe in a circular motion. Rinse the pipe with hot water and dry it with a soft cloth.
It sounds a little weird, but it really works!
Method 4: Clean the copper pipe with chemicals
One way to clean the patina (patina) is by using chemicals specially designed for this purpose. Some of them will also add a coat of wax to the pipes as they are also used for copper items such as sinks and cookware. However, they are also effective on pipes.
You can find them at most hardware stores or online. In general, first clean the area with soapy water and a cotton cloth, then apply the chemical following the manufacturer’s instructions.
Also, a household chemical option you already have is acetone. This is a chemical found in nail polish remover. It is effective in removing tarnish and corrosion from copper pipes.
However, it is also highly toxic, so be sure to use it in a well-ventilated area and avoid inhaling the fumes. It also evaporates quickly, so you have to work quickly.
Method 6: Clean the copper pipe with lemon juice and baking soda
Baking soda is another common household item that can be used for cleaning copper pipes. Not only is this mineral safe to use (for baking, after all!), but it’s also a natural abrasive. This means it is capable of scrubbing away stains, corrosion and build-up.
To use baking soda, mix it with lemon juice to create a paste. Apply the paste to the copper pipe and let it sit for 10 minutes. Next you’ll want to polish the plumbing pipes to clean.
Rinse the pipe with hot water and dry it with a soft cloth.
How to clean the inside of copper pipes
While cleaning copper water pipes, you may find that there is a lot more corrosion inside the pipes than what a simple soak in a solution can remove. To remove corrosion, use a wire brush.
- Start by disconnecting the copper pipes from the water source.
- Then, using a clean cloth and something to stretch the cloth down along the inside walls of the pipe, apply a small amount of vinegar to the inside of the copper pipe.
- Then use the wire brush to clean the tough spots of corrosion. You may need to do this several times before all the corrosion is removed.
- If you have copper pipes that are soldered, you will also need to clean the flux around the solder joint. Using a mixture of equal parts vinegar and water. Apply the mixture to a cotton cloth and then rub until clean.
- If they need more cleaning, you can also use an emery cloth or wire brush to clean hard-to-reach corners. Again, rinse the area with hot water and pat dry.
What not to use to clean copper pipes
While there are many things that will not be effective in cleaning copper pipes, we wanted to mention just a few of them here.
CLR (Calcium, Lime and Rust Cleaner)
The problem with use CLR for cleaning copper pipe is that it can remove its finish. Not only that, but it can also find certain grades of copper, and that’s definitely not something you want to happen to your pipes.
Other chemicals
There are several other chemicals that react with copper in a way that would cause more harm than good. These include hydrogen peroxide, bleach, and muriatic acid. So if you feel tempted to try any of these options, remember that they will actually make your copper reactions worse, not better.
The last steps
Now that you’ve cleaned your pipes, you’ll want to reinstall them. After that, you’ll want to turn the water back on.
A note about turning on the water: Be sure to go back and check the pipes now that the water is running through them. You will want to watch for any leaks through the joints or any leaks that may have been created by cleaning out the extreme corrosion.
As always, if you find leaks in your copper pipes, you’ll want to temporarily patch the area and then call a plumber to fix the problem for good.
In conclusion
Cleaning copper pipes is important to keep them working properly. Over time, copper pipes can tarnish with a green oxidation from tarnish, corrosion and build-up. If not cleaned regularly, these substances can cause damage to the pipe and possibly leaks.
There are many methods you can use to clean copper. The method you use will depend on what ingredients you have on hand and how much time you are willing to spend cleaning your pipes. Whichever method you choose, make sure you follow the instructions carefully and always be safe.
