How to Remove Calcium Buildup on Pool Tile

If you’re a pool owner, then you know the struggle of dealing with calcium buildup on your pool tile. It can be a stubborn and unsightly problem that requires regular maintenance to keep your pool looking clean and inviting. In this article, we will discuss the most effective methods to remove calcium buildup on pool tile, ensuring that your pool remains in pristine condition all year round.

Understanding Calcium Buildup on Pool Tile

Before we dive into the solutions, it’s important to understand what causes calcium buildup on pool tile. When your pool water evaporates, it leaves behind mineral deposits, including calcium, on the pool tile’s surface. Over time, these deposits can accumulate, resulting in a thick and hard layer of scale that is difficult to remove.

The Importance of Regular Cleaning

To prevent calcium buildup from becoming a major issue, it’s crucial to establish a regular cleaning routine. This will not only preserve the aesthetic appeal of your pool but also extend the lifespan of your pool tile. Neglecting regular cleaning can lead to severe damage to the tile’s surface, making future removal even more challenging.

Methods for Removing Calcium Buildup on Pool Tile

1. Vinegar Solution: Vinegar is a natural and cost-effective solution for removing calcium buildup. Mix equal parts of white vinegar and water in a spray bottle. Spray the solution onto the affected areas and let it sit for a few minutes. Scrub the tile using a soft brush or sponge, then rinse with clean water.

2. Baking Soda Paste: Baking soda is another effective method for removing calcium buildup. Create a paste by combining baking soda with a small amount of water. Apply the paste directly to the affected areas and let it sit for a few minutes. Scrub gently and rinse thoroughly. Repeat if necessary.

3. Commercial Tile Cleaners: If the vinegar and baking soda methods aren’t yielding satisfactory results, you can opt for commercial tile cleaners specifically designed to remove calcium buildup. These cleaners are readily available at most pool supply stores. Follow the instructions provided on the product for the best results.

4. Pool Tile Bead Blasting: In severe cases of calcium buildup, when other methods fail, pool tile bead blasting may be the most effective solution. This method involves using high-pressure air and specialized glass beads to remove the buildup. Due to its complexity and potential risk, it’s advisable to hire professionals with experience in pool tile bead blasting.

Tips for Preventing Calcium Buildup

Prevention is key to minimizing the occurrence of calcium buildup on pool tile. Here are some tips to help keep your pool tile clean and scale-free:

  • Regularly monitor and adjust the pool’s pH and calcium hardness levels to prevent excessive mineral deposits.
  • Use a pool cover when the pool is not in use to minimize evaporation.
  • Brush the pool tile regularly to remove any potential buildup before it becomes a major problem.
  • Consider installing a water softener or calcium inhibitor system to reduce the mineral content in your pool water.

By implementing these preventative measures and promptly addressing any signs of calcium buildup, you can ensure that your pool tile remains in excellent condition year after year.


Removing calcium buildup on pool tile doesn’t have to be an overwhelming task. With the right methods and regular maintenance, you can keep your pool tile looking pristine and free from unsightly scale. Remember to follow the proper cleaning techniques and consider hiring professionals if necessary. By taking care of your pool tile, you’ll enjoy a beautiful and inviting swimming pool that you and your guests can enjoy for years to come.
