How to Clean a Salt Cell for Your Pool: A Step-by-Step Guide

Maintaining a clean and efficient salt cell is crucial for optimal pool operation. Salt cells are an essential component of saltwater pools, converting salt into hypochlorous acid to sanitize the water. Without regular cleaning, the cell can become clogged with salt deposits, leading to reduced chlorination performance and potential damage. This article will guide you through the process of cleaning a salt cell effectively and safely.

Step-by-Step Process of Cleaning a Salt Cell

First, let’s explore the easiest and most effective methods to clean your salt cell. If you only need to remove light to moderate deposits, you can use a garden hose or a water jet set to a hard setting to blast off excess salt deposits. This method is effective as it removes a significant portion of the buildup without the need for any chemicals. For more thorough cleaning, especially when dealing with dense salt deposits, follow these steps:

1. Prepare the Cleaning Solution

Once you’ve removed the outer deposits, you’ll need to descale the internal metal mesh panels. Purchase a specialized cleaning solution from your local pool shop. A mild solution of water and vinegar can also be an effective option. Ensure that the cleaning solution does not come into contact with any electrical connections. The recommended solution from pool shops is the safest. However, some enthusiasts suggest using 10% diluted pool acid. Using the appropriate solution will help prevent damage to the cell and ensure that it operates efficiently.

2. Soak the Salt Water Cell

Submerge the cell in the cleaning solution you’ve prepared. A soaking time of 10-15 minutes is recommended. During this period, the solution will break down the salt deposits on the cell’s metal mesh panels. After soaking, remove the cell and rinse it thoroughly with clean water. If you still find mild deposits, you may need to repeat the process with a new solution. This step ensures that the cell is thoroughly cleaned and ready for reuse.

3. Rinse and Reuse the Cleaning Solution

The cleaning solution can be returned to its container and reused again. This not only saves money but also reduces the environmental impact. However, it’s important to note that you should not pour the solution directly into the pool as it could disrupt the chemical balance and potentially harm the pool equipment.

Caution: Handling Dangerous Chemicals

If you have advanced salt cell issues or are dealing with severe deposits that cannot be removed with water or a simple cleaning solution, it is advisable to call a professional. Professionals have the necessary experience and safety equipment to handle the process of removing and cleaning these cells. In the hands of a professional, the following steps are typically taken:

1. Disassemble and Clean the Cell

The professional will remove the cell from the pool piping, disassemble the end cap, rinse it thoroughly with a pressurized stream of water, and shake out any excess water. They may also use compressed air to dry the cell if necessary.

2. Acid Cleaning

After thorough rinsing, the cell is placed into a bucket of concentrated acid. This process helps to break down and remove tough salt deposits. The duration of this step varies depending on the severity of the buildup.

3. Neutralization and Final Rinse

Once the acid treatment is complete, the cell is pulled out and neutralized with a medium-high pH solution. This step further ensures that all residual acid is removed. The cell is then rinsed again with clean water before being reinstalled into the pool system.

Safeguarding Tip

After the professional cleaning and neutralization, the concentrated acid solution should not be disposed of in the regular drain. It is dangerous to pour down the drain or out onto the ground due to its hazardous nature. It is recommended that the professional takes the spent acid solution to a hazardous waste facility for proper disposal.

Conclusion

Keeping your salt cell clean and well-maintained is crucial for the longevity of your pool. Whether you choose the DIY approach with a mild cleaning solution or call a professional, ensuring the proper care of your salt cell will lead to a healthier and more pleasant pool experience. Always prioritize safety when handling pool chemicals and equipment.
