Surely if you have stains on the walls of the pool, you will have happened to scrub them and the stains remain. The stains we commonly encounter are salts, metals, and yellowish stains from sunscreens and oils. Each type of stain has a corresponding chemical that we can use. The stains we usually face are as follows:

• If your pool is empty and made of liner, and you have yellowish stains from sunscreens, then we can use Tile and Liner Cleaner.

• If your pool is empty and made of tiles, and you have salt and sunscreen stains, then we can use Marble, Stone, and Tile Cleaner.

• If it is full and we have salt stains at the waterline, then we can use No More Scale, which reduces the water hardness and removes salt deposits from surfaces.

• If it is full and we have yellowish stains from sunscreens, then we can address them with Ultra Kleer Clarifier, a natural 100% biodegradable product that binds and removes oils and sunscreens from both the surfaces and the waterline, as well as from the pool water.

• Finally, a difficult stain is that of metals. To remove metal stains from surfaces, we apply the specialized chemical Multi Stain Remover. The metals that have settled dissolve back into the water, thus being removed from the surfaces. We need to remove these dissolved metals from the water because when we add chlorine to the water, they can settle on surfaces, changing the water’s color. We achieve this by using the specialized chemical No More Metal, which binds the metals and removes them in the filter. Each time we add fresh water to the pool, we should add No More Metal to bind the metals and prevent them from causing problems either in the pool or to hair and swimsuits.
