Steps to Use Muriatic Acid to Clean Your Pool Salt Cell

For your saltwater pool to work well, you need to make sure the salt cell is clean and working well. Scale and mineral layers can build up on the cell plates over time, causing them to work less well and possibly need expensive repairs. One good way to clean the salt cell in your pool is to use muriatic acid. But you must be careful when handling this strong acid to keep yourself safe. Now, I will show you step-by-step how to use muriatic acid to clean the salt cell in your pool, and we will explain each step in detail.

Cleaning Pool Salt Cell With Muriatic Acid

Step 1: Get ready

Before you start cleaning, make sure you have all the safety gear you need. This includes rubber gloves, safety goggles, and a respirator mask to keep the dangerous fumes of muriatic acid from getting into your lungs. Also, make sure you work in a place with good airflow, ideally outside.

Step 2: Shutting down the pool gear

Turn off everything in the pool, like the pump and salt chlorinator, so nothing bad happens. This step is very important because it stops any water from going through the cell while it is being cleaned.

Step 3: Take the Salt Cell Out

Find the salt cell in your pool’s system next. Usually, it is put in the pipeline after the filter and before the return jet. Once you find it, carefully pull the cell away from the pipes. Depending on the type, you may need to unscrew it or use clamps to get it off.

Step 4: Getting the Cell Clean

Once the salt cell has been taken out, rinse it well with clean water. This helps get rid of any dust or small dirt that may have built up on the surface. Use a garden hose to spray water slowly on both sides of the cell, making sure to get rid of any dirt or dust that you can see.

Step 5: Make the solution of muriatic acid

Now, make the muriatic acid solution that will be used to clean the salt cell. Fill a plastic bucket or container with water, allowing enough space to add the acid. To avoid splashes or dangerous reactions, you must add the acid to the water and not the other way around. Follow the advice from the manufacturer for the right amount of acid to water. Most of the time, muriatic acid and water should be mixed at a ratio of 1:10 or 1:20.

Step 6: Let the Salt Cell Soak

Place the salt cell carefully in the prepared muriatic acid solution and make sure it is fully covered. Give the cell about 15 to 20 minutes to soak. Don’t leave the cell in the acid solution for too long, because it could hurt it.

Step 7: Give the Cell Plates a Brush

After the soaking time, gently scrub the cell plates with a soft-bristled brush or a brush made just for cleaning salt cells. Pay close attention to getting rid of any scale or mineral layers that have formed on the surface. Be careful not to scrub too hard, because that could hurt the thin layer on the cell plates.

Step 8: Washing the Salt Cell

Once the cell plates have been cleaned well, take the salt cell out of the muriatic acid solution and rinse it well with clean water. Again, use an outdoor hose to wash away all of the acid and dirt.

Step 9: Take a look at the cell

Take a moment to look closely at the salt cell. Look for any scales or crystals that are still there. If you see spots or buildup that won’t come off, you may need to repeat the cleaning process or think about using a cleaner made just for salt cells.

Step 10: Putting the Salt Cell back in

Once you’re sure that the salt cell is clean, it’s time to put it back on the water system. Make sure that all of the connections are tight and safe. Check the manufacturer’s instructions twice to make sure you’re doing it right, and then follow them to the letter.

Step 11: Turn on the equipment for the pool

After putting everything back together, turn on the pump and salt chlorinator. This lets the water move through the salt cell again and start the process of chlorination.

Step 12: Regular Maintenance

It is important to do regular upkeep on your salt cell so that it doesn’t build up too much scale in the future. This means keeping an eye on the cell for signs of scale, changing the salt levels in your pool, and making sure the water balance is right. The best way to keep the cell in good shape is to clean it at least once every three to six months, or as the maker suggests.

When dealing with muriatic acid, remember that safety is the most important thing. Always follow the directions from the manufacturer, wear safety gear, and be careful when handling the acid. Talk to a professional pool expert if you aren’t sure about any step of the process or have questions.

Other Ways to Do It

There are a few different ways you can clean the salt cell in your pool if you don’t want to use chemicals. The effectiveness and ease of use of these methods can vary, so it’s important to choose the one that fits your wants and preferences the best. Here are five other options you can think about:

Method 1: A solution of vinegar

Using a vinegar solution instead of muriatic acid to clean your pool’s salt cell is a safer and less damaging choice. Acetic acid, which is found in vinegar, helps get rid of mineral buildup and scale. Even though it isn’t as strong as muriatic acid, it can still be used to get rid of light buildup. To use this method, mix equal parts vinegar and water in a container, soak the salt cell in it for about 30 minutes, then scrub it gently with a brush and rinse it well.

Method 2: A solution of citric acid

You can also use citric acid, which is found in many common items, to clean the salt cell in your pool. It is a natural acid that can get rid of mineral buildup and scale. To use this method, mix citric acid powder or crystals with water to make a citric acid solution. Follow the directions from the manufacturer for the right concentration. Soak the salt cell for about 30 minutes in the solution, scrub it gently, and then rinse it well.

Method 3: Pool Salt Cell Cleaning Tablets

Pool salt cell cleaning pills are made to get rid of deposits and scale from salt cells. Most of the time, these pills have a mix of chemicals that break up mineral buildup. To use this way, put the tablets in the skimmer basket or dissolve them in a bucket of water as directed by the manufacturer. Let the tablet or fluid move through the cell for as long as it says to, then rinse well.

Method 4: Clean with high-pressure water

Using high-pressure water to clean the salt cell plates can help get rid of scale and deposits that are hard to move. For this method to work, you need a pressure washer or an attachment for a hose that has enough power. Carefully spray water on the cell plates, paying special attention to the areas where you can see buildup. For full cleaning, use a back-and-forth motion. Be careful not to put too much pressure on the cell plates, because that could damage the thin layer on them.

Method 5: Store-bought cleaners for salt cells

There are commercial salt cell cleaners on the market that are designed to get rid of scale and mineral buildup. Most of the time, these cleaners come in liquid or powder form. Follow the directions on how to use the cleaner on the salt cell that came with it. Most of the time, you have to soak the cell or put the cleaner straight on the plates, let it sit for a certain amount of time, and then rinse it well.

If you choose a different way to clean, be sure to always follow the advice given by the manufacturer. Also, keeping up with maintenance and keeping an eye on your pool’s salt cell will help avoid too much scale buildup and keep it running at its best.

Preventive Tips to Maintain a Clean Pool Salt Cell

Regular preventive maintenance is a must if you want your pool salt cell to last as long as possible and work well. By taking a few simple steps, you can stop the scale from building up and make your salt cell last longer. Here are six ways to make sure your pool salt cell stays clean and works well:

Make sure the water’s chemistry is right

Keeping the water’s chemistry in check is very important if you don’t want scale to build up on the salt cell plates. Check the pH, alkalinity, and calcium hardness levels and make changes based on what the maker says to do. Scale can form when the chemistry of water is out of balance, so it needs to be tested and balanced on a frequent basis.

Monitor Salt Levels

Salt is an important part of saltwater pools, and keeping the right amount of salt in the water is important for the salt cell to work well. Low amounts of salt can put stress on the cell and cause scales to form. On the other hand, too much salt can also be bad. Use a salt test kit to check the salt levels often and make changes as needed to keep them within the suggested range.

Use a system to clean salt cells

You might want to clean your pool with a salt cell device. These systems use a technology called “reverse polarity” to clean the cell plates automatically, so they don’t have to be cleaned by hand as often. The system regularly switches the direction of the electrical current. This keeps scale from building up and makes the salt cell last longer.

Set up a regular schedule for cleaning

Set up a regular plan for cleaning your salt cell. Depending on things like how often the pool is used and how the water is, the best rule of thumb is to clean the cell every three to six months. Regular cleaning keeps scale from building up and keeps things running at their best. Follow the directions from the maker for how to clean it properly.

Check and change the calcium hardness

Scale can form on the salt cell plates when there is a lot of calcium hardness in the pool water. Check the calcium hardness regularly and make changes as needed. If the amounts are too high, you might want to use a calcium remover or add more water to the pool to lower the calcium level.

Make sure the water flow is right

For the salt cell to work well and to keep the scale from building up, water must flow through it in the right way. Make sure that the pump and filter are the right size for the size of your pool and that they are working well. To keep the water flowing properly, keep the skimmer and pump baskets clean and free of waste.

By following these tips, you can make it much less likely that scale will build up on your pool’s salt cell. Regular checks, good care, and following the manufacturer’s instructions will help keep your salt cell clean and in good working order, giving you a well-kept and enjoyable swimming pool.
