Calcium buildup and algae spores in your water can disrupt how pool water sanitizers clean your water. Calcium buildup and algae increase the pH levels of your pool and thus render chlorine less effective and increase chemical loss.

To keep your pool safe and clean you need to keep your pool tile clean. Regularly test your pool water to ensure the chemicals and pH are balanced. But also make sure you scrub your tile every so often to keep the water balanced!

What’s the Best Way to Clean Pool Tiles? 

Cleaning pool tiles can be a rather large task, depending on the extent of the damage to the tiles. Regular pool maintenance is an important part of preventing calcium deposits, algae growth, and mold spores on your pool liner and tiles.

The best way to clean pool tiles is with a scrub brush and an acidic chemical. The acidic compounds break down the calcium deposits and work with the scrub brush to remove calcium deposits and algae.

However, this method really only works if you have a pool with tiles near the surface. If you’re trying to clean pool tile at the bottom of a deep pool you’ll need an extended pool brush. You may also need special cleaners to raise the overall acidity of the water to break down any mineral buildup.

How Do You Clean Algae Off Pool Tiles? 

Cleaning algae from your pool tiles can be a little time-consuming, but is well worth the effort. To clean your pool tile of algae starts with the following supplies:

  • Chlorine tablet or granular
  • Bristle brush
  • Toothbrush
  • Washcloth

Rub chlorine on the affected areas of tiles. Most of the time algae grows in the corners of the pool and the crevices between the pool tiles. Just rub the chlorine on the surface liberally and let it sit for 24 hours.

After 24 hours, brush the tile with an abrasive brush and toothbrush. The toothbrush is especially useful when dealing with algae between the tiles. Once you remove the algae, wipe the tiles with a washcloth and reapply the cleaner as needed.

How Do You Clean Calcium Deposits Off Pool Tile?

The first step to cleaning calcium deposits off your swimming pool tile is to scrape the tile. You can use a metal scraper for this task and remove the crusted calcium. However, if you’re cleaning glass tile avoid using a metal scraper or knife and utilize a rubber blade.

Next, use a spray bottle to apply an acidic solution to the tiles. This can be vinegar but you can also use a commercial calcium dissolvent. Depending on the severity of your calcium deposits you may need something more potent than vinegar.

Allow the cleaner to sit on the tiles for as long as possible before scraping them again. After scraping them use an abrasive pad and bristle brush to scrape the remaining residue.

What Can You Use to Clean Pool Tiles? 

Baking soda and vinegar are two of the best and most effective ways to remove light scaling off your pool walls. If you have a particularly stubborn calcium deposit, you can apply the baking soda and vinegar directly to the spot to dissolve it.

You can also use a vinegar and water solution to break through calcium deposits. Vinegar is very acidic, with a pH of 2-3. This makes it a potent chemical in fighting calcium and mineral stains.

However, if you have a particularly difficult amount of debris on your wall you might need a chemical cleaner. Muriatic acid mixed with water will cut through both algae and mineral stains. You should definitely wear rubber gloves and goggles whenever using this harsh acid.

Never apply muriatic acid directly to your pool tiles since it’s extremely corrosive. Muriatic acid can cut through the colors of your tiles and leave them looking bland and eroded. Dilute this acid in water with a 1-to-10 before using it on your tiles.

What Types of Tools Clean Swimming Pool Tiles?

Brushes are the best tools for cleaning pool tiles. To properly clean pool tile with brushes, make sure you apply the cleaner in large quantities to break down calcium deposits and algae. In addition to a proper cleaner, you’ll want to have the following cleaning tools in your collection:

  • Toothbrush
  • Bristle brush
  • Abrasive cleaning pad
  • Brush on a pole to clean underwater pool tiles
  • Pumice stone

Pumice stones are one of the lesser-known tools for scrubbing pool tiles clean. Pumice stone is made from hardened lava foam from volcanoes and has small air holes throughout its surface. This makes it surprisingly light but strong.

Pumice stone is especially useful for cleaning stains from pool tiles. If you remove minerals and algae but find it left behind a stain, use a pumice stone to exfoliate it out of the tile.

Use a bristle brush for cleaning pool tile after you scrape the hardened calcium buildup. Use the toothbrush to remove mold and algae from between your tiles.


Keeping your pool tile clean is an important part of pool maintenance. When contaminants build up on your pool tile it can mess up the chemical balance of the water.

Minerals and calcium buildup can especially mess up your water balance. These minerals can interfere with your chlorine and cause clogs in your pool filter. Thoroughly cleaning pool tiles should be done 2-3 times per year to keep everything running smoothly!


Can You Use Vinegar to Clean Pool Tile? 

Yes, you can use vinegar for pool tile cleaning. You can apply it directly to the pool tile, use a spray bottle to apply it or dilute it before using it.

Can You Use a Pressure Washer on Your Pool Tile?

You can use a pressure washer to clean your pool tile. But, you’ll want to ensure you use the lower pressure setting on your pressure washer.

Pressure washing your pool tile is fast and effective. However, pressure washing can be more expensive and can damage your tiles if you don’t know what you’re doing.

Apply acidic cleaner to the pool tile and gently use the low-power cleaning setting on your washer.

What Causes Calcium Carbonate Buildup? 

Calcium carbonate buildup is caused by a combination of high alkalinity levels and hot weather. As the water evaporates it leaves traces of minerals behind on your pool tile. This calcium carbonate is relatively harmless but can disrupt your pool chemicals and cleaning systems.

Can Cleaning Your Pool Regularly Prevent Stains on Tile? 

Cleaning your pool regularly will help prevent calcium buildup and other mineral deposits. Regular pool cleaning helps keep your water chemicals balanced. This will help prevent large calcium buildup from accumulating along the water line, left behind from the evaporated water.

How Do You Lower Calcium Scale in the Water?

Calcium scale is usually the result of high pH levels in the water. The best way to prevent this is to increase water acidity. The higher the acidic levels of the water, the fewer mineral deposits you’ll have in your pool.
