How To Clean Calcium From Swimming Pool Tiles

Importance of Cleaning Calcium from Swimming Pool Tiles

Calcium deposits on swimming pool tiles can be unsightly and difficult to remove if left untreated. These mineral deposits, also known as calcium scale or calcium buildup, can form a layer of white stains that detract from the overall appearance of the pool. In addition to their cosmetic impact, calcium deposits can also cause damage to pool equipment and surfaces over time.

It is important for pool owners to regularly clean their tiles and remove any calcium buildup to maintain the beauty and functionality of their swimming pools. By following a simple step-by-step guide and using the right materials, it is possible to effectively clean calcium from swimming pool tiles without causing further damage.

Materials Needed for Cleaning

Before starting the cleaning process, gather all necessary materials:

  1. Vinegar: The acidic properties in vinegar make it an effective cleaner for removing calcium deposits.
  2. Water: Mix water with vinegar in a spray bottle for easy application.
  3. Dish soap: Adding a small amount of dish soap helps break down grease and grime.
  4. Soft-bristle brush or sponge: Use this tool to scrub away the calcium buildup gently.
  5. Hose or pressure washer: Rinse off the cleaning solution thoroughly after scrubbing.
  6. Safety goggles: Protect your eyes while working with cleaning solutions.
  7. Latex gloves: Keep your hands safe by wearing gloves during cleaning.

Step-by-Step Guide to Clean Calcium from Swimming Pool Tiles

Follow these steps carefully for effective removal of calcium deposits:

A) Preparing the Cleaning Solution

1. Mixing vinegar and water in a spray bottle
– Combine equal parts white vinegar and water in a spray bottle (e.g., 1 cup each).

2. Adding a small amount of dish soap
– Add about 1 teaspoon of dish soap into the spray bottle mixture.

B) Applying the Cleaning Solution to Tiles

1. Spraying the solution onto the affected areas
– Spray the vinegar and dish soap mixture directly onto the calcium deposits on the pool tiles.

2. Letting it sit for a few minutes
– Allow the cleaning solution to sit on the tiles for 3-5 minutes to loosen stubborn calcium buildup.

C) Scrubbing the Tiles

1. Using a soft-bristle brush or sponge
– Gently scrub the tiles using a soft-bristle brush or sponge. Avoid using abrasive brushes that may damage delicate surfaces.

2. Applying gentle pressure to remove calcium buildup
– Apply moderate pressure while scrubbing in circular motions to dislodge and remove any remaining calcium deposits.

D) Rinsing Tiles

1. Using a hose or pressure washer
– Rinse off all traces of cleaning solution and loosened calcium debris from pool tiles using a hose or pressure washer.

2. Ensuring all cleaning solution and residue are removed
– Thoroughly rinse until no trace of vinegar, soap, or loose particles remains on tiled surfaces.

E) Repeat if Necessary

  1. Checking for any remaining calcium deposits

    • Inspect each tile carefully for any residual white stains or calcified patches after rinsing.
  2. Repeating Cleaning Process if Needed

    • If there are still visible signs of calcium buildup, repeat steps B-D until all residues are completely removed.

  2. Using Pool Cleaners or Robotic Vacuums

    • Consider investing in pool cleaners or robotic vacuums specifically designed for removing debris and preventing scale buildup.

B) Adjusting Water Chemistry

  1. Monitoring Calcium Hardness Levels

    • Regularly test your pool water to ensure the calcium hardness levels are within the recommended range (between 200-400 ppm).
  2. Balancing pH and Alkalinity

    • Maintain proper pH and alkalinity levels to prevent imbalances that can contribute to scale formation.

C) Installing a Water Softener

  1. Considering a Water Softening System
  2. If you have hard water, installing a water softening system can help reduce the calcium content in your pool water.

  3. Consulting with a Professional for Installation

  4. Consult with a professional pool company or technician who specializes in water treatment options to determine the best solution for your specific needs.


Regularly cleaning calcium deposits from swimming pool tiles is essential for maintaining both their appearance and longevity. By following simple steps using common household materials such as vinegar, dish soap, and brushes, it is possible to effectively remove unsightly calcium buildup without causing damage to the tiles or other components of the swimming pool.

In addition to regular cleaning, taking preventive measures such as monitoring water chemistry levels, brushing regularly, and considering additional treatment options like installing a water softener can help minimize future problems with calcium buildup on swimming pool tiles.

By incorporating these maintenance practices into your routine care regimen, you can enjoy clean and sparkling tiles while prolonging the lifespan of your swimming pool equipment.

Frequently Asked Questions (FAQs)

It’s important always follow safety guidelines, wear protective gear, and avoid contact with skin or eyes.

Q: Are there any alternative cleaning products I can use?
A: Yes, there are various commercial pool tile cleaners available on the market that can effectively remove calcium deposits. Look for non-toxic options and follow the instructions provided by the manufacturer.

Q: Can I use a pumice stone to remove calcium from pool tiles?
A: Pumice stones are not recommended for removing calcium from pool tiles as they can scratch and damage delicate surfaces. It is best to use soft-bristle brushes or sponges designed specifically for this purpose.
