Over time, your pool tiles may accumulate a grimy white covering because of hard water. This hard water residue typically consists of calcium and magnesium deposits that become stuck on pool tiles as pool water evaporates.
Though these stains can detract from the appearance of your custom swimming pool, you can remove them through the following cleaning process:
- Acquire Muriatic Acid- Muriatic acid is frequently sold at places where pool cleaning supplies are carried. In addition to being used to control the pH of pools, it can also be used to clean swimming pool tiles. It's important to note that muriatic acid gives off strong fumes, so care should be taken when transporting containers of this substance and when working with open containers.
- Drain Away Water- Before removing hard water stains, you'll have to drain the water out of your pool. You don't necessarily have to completely empty out pool water. However, you'll get the cleanest pool if you do empty out all water so that you can go all out with applying your cleaning solution.
- Protect Yourself- It's important to wear rubber gloves and eye goggles when working with muriatic acid. Make sure you put these safety devices on before you open containers of muriatic acid and begin pouring the substance.
- Make a Solution of Muriatic Acid and Water- For a pool cleaning solution, you can mix a solution of one part muriatic acid and nine parts water. You might also want to consult the manufacturer's recommendations on your container of muriatic acid to see the exact ingredients they recommend for a pool cleaning solution.
- Spray the Solution Over Stains and Begin Scrubbing- Once you've got your solution ready, you can spray it on the stains and scrub them away with a nonabrasive scouring pad. However, don't do the scrubbing from inside the pool. It's better to stand outside the pool and lean over to scrub to avoid too much exposure to the fumes from the muriatic acid.
- Rinse Away the Solution- After you've finished scrubbing and you've removed any stains, you can rinse away the solution with a garden hose. Afterwards, wipe the newly clean tiles with cloths or rages to get rid of any leftover residue.
- Dispose of Your Cleaning Solution- You might want to contact your local municipal to look into the best way to dispose of a caustic acid like muriatic acid.
- Have Your water Analyzed- If you want to prevent future stains, you might want to have your pool water analyzed to determine how hard your water is. If you have severe hard water problems, try looking a water softener system.
