Pool Tile Cleaning & Calcium/Scale Removal

Get Rid of That White Crusty Buildup

That white, chalky line along your pool tile is calcium scale. It builds up over time from hard water and unbalanced chemistry. It looks terrible and gets harder to remove the longer you wait. Regular scrubbing barely makes a dent because the buildup is actually bonded to your tile surface.

We have been cleaning pool tiles in Hawthorne, CA since 2024. Our professional tile cleaning removes even the worst calcium deposits without damaging your tile or grout. We use specialized equipment and techniques that bring your waterline tiles back to their original beauty. No harsh chemicals that could harm your pool finish.

What Causes Calcium Buildup

Calcium scale happens when your pool water has too much calcium or when the pH and alkalinity are too high. As water evaporates at the waterline, it leaves minerals behind. These minerals accumulate and harden into scale. Here is what makes it worse:

• •Hard tap water with high calcium content from your local supply
• •pH levels consistently above 7.8 allowing scale to form
• •High total alkalinity making calcium less soluble in water
• •Water loss from evaporation concentrating minerals at the waterline
• •Heated pools that accelerate calcium precipitation
• •Lack of regular water testing and chemical balancing

If you skip regular pool maintenance, calcium builds up faster. Southern California has naturally hard water, which means this is a common problem in our area.

How We Clean Your Tiles

We use professional-grade bead blasting or pumice stone techniques depending on your tile type and the severity of the buildup. Bead blasting uses tiny glass beads under pressure to gently remove scale without scratching the tile. It is fast and effective for heavy deposits. For lighter buildup or delicate tiles, we use specialized pumice blocks that scrub away calcium safely.

We work carefully around your waterline to restore the entire surface. This includes tile grout lines where calcium loves to hide. After cleaning, we can also apply a tile sealer that makes future cleaning easier and helps prevent new buildup. The whole process usually takes a few hours depending on your pool size.

Once your tiles are clean, we recommend keeping up with water chemistry to prevent it from coming back. Our weekly pool service includes water testing and balancing to minimize future calcium deposits. We also offer one-time deep cleaning if the rest of your pool needs attention too.

Why Clean Tiles Matter

Clean tiles make your whole pool look better. That white calcium line is the first thing people notice, and it screams neglected pool. Removing it instantly upgrades your pool appearance. Clean tiles also feel better when you grab the edge of the pool or sit on the steps.

Beyond looks, calcium scale can damage your tile over time. Heavy buildup can actually pull tile off the pool wall when you try to remove it yourself. Professional cleaning prevents this damage and extends your tile life. We serve Hawthorne and surrounding areas with honest pricing and quality work. Call us today for a free estimate.
