Use Vinegar & Elbow Grease To Tackle Small Areas

How To Remove Calcium From Pool Tile (and keep it GONE!)

If you decide to tackle tile stains with vinegar and elbow grease, get ready to put some time in. Choose a brush, stone, or sponge designed for your type of swimming pool. Stiff brushes or a pumice stone might be okay on plaster but will scratch fiberglass and delicate tiles, which should be cleaned with a soft textured sponge.

Mix some vinegar with a small amount of water and use the brush or sponge to scrub tiles gently. This can help remove small areas of calcium carbonate buildup.

How To Clean Pool Tile With Pressure Washer

When people talk about using pressure washers to clean calcium from pool tiles, they dont usually mean real pressure washers. In fact, if you try to use a regular pressure washer, theres a good chance it wont work the way you have intended.

Instead, what people are usually referring to is something that professional pool cleaners use called bead blasting. This process uses compressors to blast beads, sand and other materials at your tile at a high speed to basically blow or scrape the calcium deposits away.

It works amazingly well, and its fast. Best of all, you arent doing the labor!

Unfortunately, it can also be priceyespecially if you plan to do it without the help of a pool cleaning service.

Tips For Preventing Calcium Scaling

Because calcium scaling is such a pain to remove, it is best to stay on top of preventing it by taking the following precautions:

  • 1Lower your pH and alkalinity
  • 2Use a pool clarifier to clump the calcium films together, then vacuum them away or let your filter take care of them
  • 3If you seem to be battling unusually high amounts, avoid shock with added calcium like calcium hypochlorite
  • 4Brush your pool regularly to keep calcium from building up

The most effective chemical for removing calcium scale is muriatic acid , but you need to take some safety precautions when using it.

Always wear rubber gloves, goggles and clothes that cover your body well to prevent burning and skin damage from accidental contact.

If you have light scaling, you may be able to get away with using a vinegar water solution and a scrub brush.

And if you have a ceramic tile pool, it is better to try a gentler solution like this before jumping to the acid washing.

Removing Calcium On Efflorescence On Stonework And Tile:

Similar to calcium scale from water, efflorescence occurs in grout between stone or tiles near water fixtures.

Whatever is causing the moisture to come from behind the tile or stone through the grout will bring calcium. This is the same type of process that causes stalagmites.

There are times that the moisture will come from the pool. A sealer may be used on the tile to help provide a barrier. For the larger stone or tile above the water, you may need to seal the water sources to prevent efflorescence.

For those who have hard tap water, you have my sincerest and deepest sympathies.

Even when you have hard water, you can control and prevent calcium deposits with a little elbow grease, cleaning agents and good water balance.

Use A Muriatic Acid Solution

How to remove calcium deposits from swimming pool tiles

Muriatic acid is your last resort if vinegar and tile cleaning products arent strong enough for your pools calcium buildup. The great thing about using this product is that it also lowers your pools pH level, which helps prevent calcium from building up again.

You can find bottles of muriatic acid at your local pool store with instructions for usage on the back. Be sure to follow the directions carefully because skin exposure to muriatic acid can cause irritations and severe burns.

If the calcium scaling continues to form on the walls of your pool after you apply these methods, it means the buildup has reached the pools pipes and filtration system. You need to call a pool cleaning service, so they can scrape the deposits from the pump for you.

First The Facts On The Appearance Of Calcium

There are three reasons why calcium accumulates in your pool. These reasons are:

Hard Water

Hard water brings and leaves calcium residue. In areas where hard water is present, it is noticeable in faucets, sinks, and tubs.


The southern part of the USA has high temperatures for most of the year. It means that the water evaporates and raises the temperature of the water itself.

If your swimming pool water has a high pH, the combination of high alkaline and warm water will begin to form a calcium scale in your oasis.

How To Clean Swimming Pool Tiles

How to remove calcium deposits from swimming pool tiles

The best way to clean swimming pool ties is to treat your pool for several weeks with our calcium dissolving products. It is best to do this before trying to remove it manually. This is because our treatments soften hard calcium which makes removal much easier and simple to do. If you attempt to remove calcium without our pre-treatment is as hard as concrete and strongly adheres to the tiles. This means that you will likely cause severe damage to the tiles in trying to scratch it off. This can lead to chipped, scratched and broken tiles. We do not recommend using rubbing blocks, paint scrapers or pumice stones on tiles as these can scratch or crack the tiles permanently. Our calcium treatment kit is the best treatment option for softening waterline calcium buildup on swimming pool tiles.

What Causes Scale In Pools

Calcium carbonate scale can form along the waterline of the pool as evaporation increases during the summer. Scale itself is a white translucent color, but is often mixed with dirt and algae to appear darker.

Calcium crystals can form as nodules dotting the surface of the pool, or on ladders and light rings, or as crusty deposits in corners. Minerals like calcium commonly form sheets of scale, covering the entire pool surface in a thin layer.

The most common cause of calcium scale in pools is the result of high calcium hardness, over 400 ppm, yet is triggered by high Alkalinity, high pH and high water temperatures. Some will tell you to drain the pool if over 400 ppm, but not necessarily!

The best way to control for the various elements leading to pool scaling is to perform a regular test known as the Langelier Saturation Index, or LSI for short. An LSI test determines a pools preponderance for scaling or etching. A pool is considered to have a balanced LSI when results are -0.3 to +0.3. Test results below -0.3 indicate a prevalence toward corrosion and above +0.3 and your water is scale-forming.

The math is a bit complicated to calculate the LSI, but you can use the Pentair LSI Tool just plug in your water test levels and it crunches the numbers for you! The tool is then used to see the effect of adjusting chemical levels.

How To Remove Calcium Deposits From Swimming Pool Tiles With Muriatic Acid

Muriatic acid is an acid that is hydrochloric-based and makes an excellent limescale remover. Muriatic acid washing is powerful, so we recommend wearing protective goggles and rubber gloves.

To efficiently eliminate hard water stains on tile, utilize the powerful ingredients in muriatic acid, which eat through limescale.

Combine one part muriatic acid with eight parts water in a large spray bottle. Spray the acid wash on the affected areas and let it sit for five minutes. With a nylon brush, continue scrubbing the limescale buildup until it is clean.

Finish your tile cleaning by rinsing the area with clean water. If you have to remove limescale buildup in your home, like a toilet or shower, consider using muriatic acid.

Why Does Calcium Accumulate On Pool Tiles

Calcium deposits in pools are mostly caused by hard water. Calcium scaling occurs when the water hardness exceeds 400 PPM. If you allow the pool water to have a high PH value, calcium deposits will form along the waterline. As may be seen, Algae can sometimes be covered by the calcium deposit. The temperature of the water rises in the summer, and water evaporates, causing calcium deposits to accumulate on top of the water layer. Calcium deposits are caused by this as well. The pressure washer is the tool that successfully cleans calcium deposits from swimming pool tiles.

Prepare Your Cleaning Solution

Fill your bucket with a gallon of water. Pour 8 ounces of muriatic acid into your measuring cup, then slowly pour that acid into the water. Always pour acid into water instead of the other way around, because acid is more likely to splash out the other way. Another thing to keep in mind is that you want to pour slowly, because mixing the two together can produce heat, causing the mixture to boil.

Exposure To Water & Chemicals

Though spills occur on indoor tiling, these normally get cleaned immediately. While liquid spills may cause grout on these tiles to break down, it wont damage the tile. Swimming pool tiles, however, form a bond with the tiles adhesive material, and further, they usually have water absorption rates of less than 0.5%. Swimming pool tiles must also resist erosion and pool chemicals.

S To Eliminate Calcium From Your Swimming Pool

There are several ways to help eliminate the calcium from your swimming pool. However, there are three popular methods that most people use:


A natural cleaning agent helps to remove the early appearance of calcium on the swimming pool tile. Just get an old toothbrush or a hand brush, and a spray bottle with vinegar. Spray the solution on the affected area and brush it out. If you notice that the calcium doesnt go away, then it could be more serious.

Muriatic Acid

This harsh and dangerous cleaner is available at your local home improvement or pool supply store. You MUST NOT ENTER the swimming pool while using the product.

The chemical is a powerful one that penetrates nostrils, mouth and can affect your vision. It is vital to have goggles, rubber gloves, and a mask or a respirator if you are handling the cleaning yourself.

Removing Scale On Vinyl Liners:

Although the slick surface of vinyl liners can make calcium scale less likely to form, scale can deposit on vinyl liners when conditions are right.

As opposed to metal stains on liners, mineral scale can be felt with your hands and feet, rough and scaly to the touch. In extreme cases, it can be very rough and snag swimsuits and give the kids a bad case of pool toe.

To remove scale from vinyl pools, you have to be a bit more careful than other pool types, to avoid damaging the vinyl or making it look worse. The Stain Eraser for vinyl pools is tough enough for stains and scale, and works great for small scale problems.

For waterline scale on a vinyl pool: lower the water level and spray white vinegar from a spray bottle. Spray a few feet, then scrub the surface with a textured sponge or scrubber, then rinse off. Most visible scale will need an acid stronger than vinegar, however. Add 4-8 oz. of Acid Magic or Instant Liquid Acid to a cup of water in a spray bottle, and repeat the process. Tile patterns can be removed from your liner if the acid is too strong, so test in small areas and gradually work-up in strength.

For all-over scale in a vinyl pool, an accepted treatment is to:

  • Add a full dose of Stain Away or Scale Free to lock-up calcium scale.
  • Lower the pH level to 6.5 for two days*, brushing the pool 2-3x per day.
  • Return pH level to 7.4-7.6 continue with maintenance doses of Stain Away.
