How to Get Rid of Copper Stains in Swimming Pools

If your pool has a brownish-green stain caused by copper, you should learn how to remove copper stains. Their may be an organic material, such as leaves and berries, which can also occur as a result of copper leaking from plumbing or filters. Another culprit is algaecides which contain copper. It is unlikely that these products will permanently damage your pool, but they can add to the problem.

Cause of Stains

Several factors contribute to copper stains, including city water, algaecides, and copper piping in heat exchangers. Depending on the source, they can appear in different colours. A green or blue stain indicates that copper is present in sulphate form, while a brown or purple stain means that copper is in an oxidized state. This is the most difficult type to remove, but it will not damage the surface if left alone.

Organic stains are brown or green and result from leaves, foliage, and seeds floating in the pool. These substances will sink to the bottom of the pool and leave behind a residue. Some insects, berries, and algae can also cause stains on your pool. Metal stains are reddish-brown and are caused by iron, copper, and manganese. Copper tends to turn a teal-blue or turquoise colour.

Special Products

Another option is “A+ Stain Remover,” a product that uses ascorbic acid to dissolve even the toughest organic stains. These products can be purchased at any pool store. Chlorine won’t remove stains from metal pools, but some products contain citric or ascorbic acid, which is more effective against copper-based stains. To test for metal levels, you can collect a water sample and take it to a pool store or purchase a metal test kit.

Once you have removed the stains, it is time to restore the water’s chemistry. After you’ve used the granular and liquid stain removers, it’s time to add a sequestering agent to trap any remaining metals in the water. Fortunately, there are now phosphate-free options that do the job. It’s important to note, however, that liquid stain removers can also introduce phosphates into the water.

Before using any aforementioned products, you should first test the water’s pH level. Low pH levels can cause copper to corrode. Consider adding a metal-eliminator pack to your pump basket or skimmer basket to ensure your pool stays as clean as possible. These products are especially effective against organic stains. They can be added to the water as needed, and you should see a visible improvement within a day or two.

Other Cleaning Methods

Another popular way to remove copper stains in pool is to mix borax with water to form a paste. Leave the mixture on for several minutes before scrubbing it away with a sponge. Repeat the process if the stain is extremely persistent. Baking soda can also be used to remove copper stains. It can be mixed with water and brushed off the pool with a sponge. To prevent any further deterioration of your pool, you should always test the water once you’ve completed the cleaning.

Ascorbic acid is another method for removing copper stains from your pool. This acid is high in acidity and can help lift the stains from the surface. If you’re not comfortable using the acid, you can crush vitamin C tablets and rub them against the stains. These tablets have the effect of dissolving the stain and whitening them. Vitamin C is also effective against larger metal stains.
