A sparkling, crystal-clear pool is the ultimate backyard retreat, offering relaxation, fun, and a refreshing escape from the heat. However, keeping your pool looking pristine requires more than just clean water—the condition of your pool tiles plays a huge role in maintaining its overall appearance. Over time, pool tiles can accumulate stubborn calcium buildup, algae, and grime, causing them to look dull, stained, or even discolored. If left untreated, these deposits can become increasingly difficult to remove, making routine maintenance essential to preserve both the beauty and hygiene of your swimming area.
In this comprehensive guide, we’ll walk you through everything you need to know about cleaning and maintaining pool tiles the right way. You’ll learn about the causes of tile buildup, the best cleaning methods for different types of stains, and preventive measures to keep your tiles in top condition for years to come. Whether you prefer DIY solutions or commercial cleaning products, this guide will provide safe, proven techniques to help you achieve a spotless and sparkling pool.
Why Do Pool Tiles Get Dirty?
Before we dive into the cleaning process, let’s understand why pool tiles develop buildup over time. The most common culprits include:
1. Calcium Deposits (Scaling)
- One of the biggest challenges pool owners face is calcium scaling, which appears as white, chalky residue on tiles.
- Scaling occurs due to high calcium hardness levels in the pool water, especially in areas with hard water.
- When water evaporates, it leaves behind mineral deposits, which form scale buildup on tiles.
2. Algae and Organic Stains
- If your pool’s chlorine levels drop too low, algae can start growing along the waterline, creating green, yellow, or black stains.
- Leaves, dirt, and debris that settle in the pool can also stain tiles over time.
3. Oil and Chemical Residue
- Sunscreen, body oils, and lotions from swimmers stick to the tiles, forming a greasy film that attracts dirt.
- High chlorine levels or other chemical imbalances can also cause discoloration.
By understanding these common issues, you can prevent buildup before it becomes a major problem.
How to Clean Pool Tiles: Step-by-Step Guide
Now that we know why pool tiles get dirty, let’s dive into the best cleaning methods to keep them looking new.
Step 1: Gather Your Cleaning Supplies
Before starting, make sure you have the right tools and cleaning solutions for the job. Here’s what you’ll need:
✔ Pool Tile Brush – A soft-bristle brush or pumice stone to scrub away buildup.
✔ Scouring Pads or Melamine Erasers (Magic Erasers) – Great for tackling light stains.
✔ Pool Tile Cleaner – Commercial pool tile cleaning solutions or natural alternatives.
✔ Muriatic Acid (for tough calcium stains) – Effective at breaking down scale buildup.
✔ Bucket of Water – To rinse and dilute cleaning solutions.
✔ Protective Gloves and Goggles – For safety when handling strong chemicals.
Step 2: Choose the Right Cleaning Method
Different stains require different cleaning techniques. Let’s explore the best methods for tackling calcium buildup, algae stains, and oil residue.
Method 1: Using a Pumice Stone (For Calcium Scale)
A pumice stone is one of the most effective ways to scrub away stubborn calcium deposits.
✔ How to Use:
- Wet the pumice stone and the pool tiles to prevent scratching.
- Gently rub the stone in a circular motion over the calcium buildup.
- Rinse the area with pool water.
Pro Tip: Never use a pumice stone on vinyl or fiberglass pools, as it can scratch the surface.
Method 3: Muriatic Acid (For Heavy Calcium Deposits)
For extremely stubborn calcium scale, you may need to use muriatic acid. This is a strong chemical, so use it with caution.
✔ How to Use:
- Dilute the acid – Mix one part muriatic acid with ten parts water in a bucket.
- Wear protective gloves and goggles.
- Use a brush or sponge to apply the solution to the affected areas.
- Let it sit for 1-2 minutes, then scrub lightly.
- Rinse the area thoroughly with pool water.
Warning: Never mix muriatic acid with other chemicals, and always add acid to water (not the other way around) to avoid dangerous reactions.

Preventing Future Buildup on Pool Tiles
Now that your tiles are clean, preventing future buildup will make maintenance much easier.
1. Maintain Proper Water Chemistry
✔ Keep calcium hardness levels between 200-400 ppm to prevent scaling.
✔ Test your pH and alkalinity weekly to avoid imbalances that lead to deposits.
✔ Shock your pool regularly to prevent algae growth.
2. Use a Tile Sealer
Applying a tile sealer creates a protective barrier, preventing calcium and grime buildup. Reapply every 6-12 months for the best results.
3. Regular Brushing & Skimming
✔ Brush pool tiles weekly to prevent grime and algae from settling.
✔ Skim the pool daily to remove leaves, bugs, and debris that can stain tiles.
4. Reduce Hard Water Deposits
✔ If you live in an area with hard water, consider using a water softener or adding a scale inhibitor to the pool.
5. Keep Oil and Sunscreen Under Control
✔ Encourage swimmers to rinse off before entering the pool.
✔ Use enzyme-based pool clarifiers to break down oils.
Final Thoughts: Keep Your Pool Tiles Looking New
Cleaning pool tiles doesn’t have to be difficult—with the right methods and regular maintenance, you can prevent stubborn buildup and keep your pool looking beautiful year-round.
Key Takeaways:
✔ For light stains: Use vinegar, baking soda, or a commercial tile cleaner.
✔ For calcium deposits: Try a pumice stone or diluted muriatic acid.
✔ For algae and oils: Brush weekly and maintain proper chlorine levels.
✔ Prevent future buildup by maintaining balanced water chemistry and using a tile sealer.
