All you need to do is heat a rag or a small towel in the microwave, pour vinegar on it and clean your pool tiles. Vinegar contains molecules that react with calcium to separate the deposition and eventually clean your pool tiles.
For light, thin calcium deposits, try using a soft brush (such as an old toothbrush) and a solution of vinegar and water. If that doesn't work, try cleaning the tile with a solution of water and muriatic acid (you can find muriatic acid at your local hardware or pool supply store).
White Vinegar
Mix a 50/50 solution of vinegar and water, dip a sponge or soft cloth into it, and scrub that residue away. It's OK if a little bit of it makes it into the pool water, but if you're concerned, test the water after using vinegar, and adjust any levels if necessary.
Unlike chlorine, vinegar is non-toxic and can be used to get rid of algae in pools. It also destroys mold, weeds and other microorganisms.
Mix vinegar, baking soda and hot water in a bucket. Use a mop to clean the liner. This will kill mold and mildew and leave the liner clean and fresh smelling.
Calcium buildup is a white and scaly buildup caused by high pH or alkalinity levels in your pool water. This causes calcium carbonate to separate from the water and stick to the pool tile.
Can CLR be used on pool tile? Unfortunately, we do not recommend using CLR on pool tile. It could remove the finish from the tile. In addition, if CLR comes in contact with chlorine, it could result in toxic fumes.
Clean Tiles with an Acid Solution. When using chemicals to clean your pool's tiles, you want to wear all the right protective clothing. Once you're suited up, you can then mix 1 gallon of water with 1 gallon of muriatic acid. When mixing, you want to slowly add the acid into the gallon of water.
In cases where your dirt and grime is only minimal, you can use homemade cleaners as such vinegar with water, baking soda and vinegar, toothpaste or even dish soap to remove the deposits. For tough stains or calcium silicate scaling, you'll need to clean the area using a pumice stone.
According to Pack, all you have to do to get your dirty pool looking clear again is simply put a Magic Eraser in the pool skimmer basket. Based on Pack's post, the Magic Eraser pretty much works like its name suggests.
Cleaning with a pumice stone takes a lot of time and effort. Depending on the amount of calcium build up this could take hours and hours over several weekends. And contrary to what your pool store or pumice packaging may say, pumice does scratch the tile surface.
To protect the shine on your pool tiles once they've been cleaned, you should apply a clear coating to them. There are specially formulated waxes that can be purchased as pool care stores, and there are also chemical coatings that can be put on over your pool tiles.
Along with balancing the pH levels of your pool water, muriatic acid is strong enough to kill mold, remove rust stains, get rid of calcium deposits, and clean the surfaces of your pool.
Baking soda is safe and straightforward to use, while also providing your pool with a clean, clear, sparkling water that is pleasant to swim in. Baking soda does not sting the eyes; neither can it cause drying of the skin.
Bleach, like any other kind of pool treatment, is best used in specific concentrations -- that is, you'll want to be able to detect a certain amount of chlorine in your pool water. Too little, and you won't effectively sanitize your pool water and surfaces. Too much, and your pool water might become too harsh to use.
Is It Safe to Clean Pool Tiles with a Pressure Washer? Yes, as long as you take the right precautions. Firstly, you'll need to use the right type of nozzle and PSI to make sure that you clean the tiles without causing any damage. You should also make sure that you are taking personal safety precautions.
Once media-blasting is complete, pool tile installations should be sealed, protected and regularly maintained per the other sections of this guide. NOTE: Always wear personal protection equipment, follow instructions for product use and protect surrounding surfaces when using cleaning or sealing products.
