The purpose of this blog is to provide you with tips on how to remove calcium deposits. What do you do when you see the white, chalky deposits running up your pool tiles, primarily black? These are called calcium deposits. It will not affect you if left unattended, but this sediment causes harm to your pool and its decorative elements over time. Calcium deposit results when hard water primarily high in calcium content is left to dry or evaporate on pool surfaces where the pH levels are high and the temperature of the water is warm. However, these deposits should only be seen as a nuisance because with the correct method, practice tackling the deposits, and your tiles will be spotless and look as good as new. This blog will explain crystalline calcium, how to clean calcium buildup from your pool, whether it is only a small amount or more, and how you can quickly stop it from returning.
How to Get Rid of Calcium Deposits From Pool Tiles (Step-By-Step Guide)
The 1st Move: Assess the Severity of Buildup
The first step in pool calcium removal is knowing the extent of the buildup. Light deposits consist of calcium carbonate, which requires some elbow grease to scrub out, and heavy deposits consist of calcium silicate, which is not easy to clean; thus, caustic cleaners are employed. Knowing how to differentiate the two deposits is important because that will guide you in choosing a cleaning method.
For Light Buildup Removal (Calcium Carbonate)
Regarding the above, it is highly possible that calcium build-up isn’t easy to remove due to calcium carbonate. Here’s how to remove it.
Wet the Tile – Pool tile cleanup starts with wetting the tiles. This prevents scratching or damage as you work.
Scrape Off Buildup – Use a plastic scraper to avoid scratching the tile surface. A plastic putty knife is best for glass tiles because it is both non-destructive and efficient.
Apply a Calcium Releaser – Mix equal parts vinegar and water into a spray bottle. Then, apply the solution to the affected area. Vinegar is a gentle, organic acid that can dissolve calcium carbonates. After this, allow for 15 minutes of soaking.
Scrub with a Soft Brush – Evacuate the loosened deposits using soft bristles instead.
Seal with Plastic Wrap (Optional): For stubborn areas, the treated area should be wrapped in plastic. This will prevent the vinegar solution from evaporating and improve its soaking properties.
For Heavy Buildup Removal (Calcium Silicate)
If the buildup feels rough and doesn’t budge with vinegar, it may be calcium silicate. This form of calcium requires a stronger solution to dissolve it:
Use a Calcium Dissolver – Mix a calcium dissolver, such as a 1:10 hydrochloric acid and water ratio. You can also use a commercial product specifically designed for tricky calcium removal.
Important: Customers are advised to wear gloves and goggles when mixing and using the chemicals.
Apply and Seal with Plastic Wrap – The treatment dressing is then applied, and plastic wrap is placed over it. This process takes two hours at most. This period allows the acid moisture to decompose the calcium silicate.
Scrub Thoroughly and Rinse – Using a scour brush, clean the area. Pour out clean water and do this again if needed. For sporadically seen deposits, you will have to do this cycle more than once or twice.
The Final Step: Rinse and Inspect the Tiles
Clean the surface of the tiles efficiently with either steel wool or a hard plastic brush. After cleaning the stains, a thorough wash of the surfaces will help remove any extra clay particles. The surface of the tiles should be checked to ensure that the calcium deposits present have been completely cleared.
Bonus Tip: Protect Your Tiles from Calcium Buildup
If the tiles are already clean, it is advisable to take extra precautions: Put on a tile sealer. If you put on this product, you will be able to remove calcium stains the next time with help because you will prevent their formation during that time. Get a Robot Pool Cleaner—A robotic swimming pool cleaner can help manage the pool’s water chemistry, reducing the likelihood of mineral deposits collecting on the tiles’ surfaces.
Final Thought: Keep Your Pool Tiles Spotless
Of course, we all know that controlling calcium deposits takes some effort, but the effort is worth it, especially if you want to keep the pool looking good throughout the seasons. Make a habit of checking the condition of your tiles periodically, scrub when necessary, and apply a tile sealer on areas that require extra shielding. These little activities will save you more time and energy since you will concentrate on enjoying a clean and bright pool throughout the season. With such information, you will undoubtedly have a calcium-free deposit pool—swim-ready all summer long!
