Purchasing a pool stain remover is no easy task since there are a plethora of options you can choose from. On top of that, there are many specifications you need to take into account to make your final decision. That is why, to help you navigate the market, we have prepared a comprehensive buying guide to explain everything you need to know about pool stain removers.
If you want to purchase a pool stain remover, here are some features you should look for.
Some pool stain removers are manufactured to wipe out stains on any surface, while some specialize in one type of surface. To know which stain remover will work best for your pool, it is essential first to know what kind of surface your pool has, and then purchase a cleaner capable of cleaning that type of surface. Otherwise, you risk damaging the surface of your pool, or you won’t be able to clean it effectively.
It is vital to know if your pool stain remover is organic or not since it can have poor effects on your health if you swim in your pool right after using it. Chemical pool cleaners can leave behind residue on the surface of your pool which can contaminate the water. This is dangerous, especially if you have kids or pets, as they can get sick or develop rashes on their skins after swimming in the contaminated water. That is why it is always a good practice to get a cleaner that is 100% organic.
If you have incredibly stubborn stains on your pool, you can choose to employ a chemical cleaner to eliminate all the grime and stains. That said, make sure that no chemical residue is left; properly rinse the pool’s surface once you have removed the stains.
Here are the most common types of stains that can invade your pool:
If you see greenish-brown spots around or inside your pool, they are most probably organic stains. They are usually caused by falling leaves, mud, and worms, which explains their color. If the stains are red or blue, they are most probably caused by berries that dropped into your pool. If the color is plain green, it is most probably caused by algae.
You can remove most organic stains by just scrubbing them out. For algae, algaecides can be used to get rid of them effectively. If all your efforts to remove these stains don’t work, you should contact a professional pool cleaner.
If your stains aren’t organic, they’re likely to be metallic. Metallic pigments are caused by pool and lawn chemicals that contain fragments of metals such as steel and iron, which get deposited on your pool linings. Chlorine and saltwater chlorine pools can easily get infested with metallic and mineral stains.
Removing metal/mineral stains can be tricky since they may come from a variety of causes. The ideal action against them is to take a sample of your pool water and show it to a professional pool cleaner, who will then tell you which pool stain remover would be optimal to use.
Scale deposits, also known as calcium stains, are a mixture of dirt and oils that can appear on your pool as a whitish crust. If you see calcium deposits in your pool, this usually means that the pH or calcium levels in your water are too high. Changes in temperature and evaporation can also cause these stains.
The optimal way to remove scale deposits is by draining your pool and cleaning it with acid. It may be preferable to call a professional who can take a look at your pool and decide the best course of action.
It is not always necessary to do so. Some pool stain removers can clean up your pool without affecting the water or making your pool cloudy, while some other methods may require draining.
Good quality pool stain removers will eradicate any unsightly spots and completely wipe them off. However, if they’re old and accumulated stains, they might require a little scrubbing.
Different pool stain removers are compatible with various surfaces, while some can be used on every type of surface. Make sure to read the instructions on your pool cleaner to ensure you are using the right type.
Swimming pools can be a menace to take care of. We recommend following basic steps such as frequent inspections and regular cleaning to help maintain its condition.
