There’s nothing quite like taking a dip in the pool on a hot summer day, but before diving in, you need to make sure that your pool is clean and the water is sanitary. Swimming in a funky pool is a pretty gross idea to begin with, and potentially getting sick because you decided to take the risk is about as far from having fun as it gets. 

A good pool cleaner will help eliminate built-up dirt, algae, and any harmful bacteria in the water. After using one (or a combination if you want to be extra thorough) of these products, you’ll be left with a clean pool and clear water in which you can spend many lazy afternoons stress-free. After our research, we determined the Essential Values Pool Cleaner to be the best overall, although there are some other great picks we’ve selected as well, based on rave reviews on Amazon which you can find below.

The Swimming Pool Cleaner from Essential Values is an all-in-one solution that’ll clean your pool and prevent staining, while also keeping the water clear and pH-balanced due to the natural citric acid base formula that’s free of harsh chemicals. One container of this pool cleaner can treat 20,000 gallons of water, and all you have to do is let the solution sit for ~12 hours, give the walls and floor a quick wipe down (manually, or with a robot pool cleaner), and then turn on the pump to let your pool’s filter do the rest. 

This pool cleaner gets the top spot on our list because it is suitable for a variety of surfaces, has a great track record of providing reliable results, doesn’t mess with the water’s pH balance, and is good enough to be used as a stand-alone solution for most pool cleaning needs, providing great value for money.

Pros
  • Non-toxic and no harsh chemicals

Pool Cleaners: A Buyer’s Guide

Now that you’re well-familiar with the internet’s favorite pool cleaners— here’s a short buying guide to help you get started.

Factors to Consider Before Buying a Pool Cleaner

Types of pool cleaners and their formulations

  • 1. Clarifiers:

    • Formulation: These typically contain flocculants like aluminum sulfate or polyacrylamide. Flocculants work by attracting and clumping together tiny suspended particles like dirt, dead skin cells, and pollen in the water column.
    • Effects on Pool Surfaces: Clarifiers are generally safe for pool surfaces when used as directed. However, overuse can lead to cloudy residue on the walls and floor, requiring additional filter backwashing.
    • Combinations to Avoid: Don’t use clarifiers with algaecides containing copper, as they can deactivate the flocculant and reduce its effectiveness.

    2. Algaecides:

    • Formulations: These come in various forms and target different types of algae. Common types include:
      • Quat Algaecides (Liquid): Quaternary ammonium compounds disrupt the cell walls of algae, killing them.
      • Triazine Algaecides (Granules or Tablets): Prevent new algae growth by interfering with photosynthesis.
      • Chelated Copper Algaecides (Liquids): Kill various algae types but can stain pool surfaces if used excessively.
    • Effects on Pool Surfaces: Copper-based algaecides can stain pool surfaces, especially light-colored liners. Overuse of any algaecide can irritate swimmers’ eyes and skin.
    • Combinations to Avoid: Don’t mix different types of algaecides, as they can interact and reduce effectiveness. Avoid using copper-based algaecides with chlorine, as it can deactivate the copper.

    3. Shocking Treatments (Oxidizers):

    • Formulations: These often contain chlorine shock (sodium dichlor) or non-chlorine shock (potassium monopersulfate). Chlorine shock raises chlorine levels for a powerful sanitizing effect, eliminating bacteria, organic contaminants, and stubborn algae blooms. Non-chlorine shock oxidizes contaminants without significantly raising chlorine levels.
    • Effects on Pool Surfaces: High chlorine levels from shocking can damage pool liners and irritate swimmers’ eyes and skin if not used properly.
    • Combinations to Avoid: Never mix different shocking products, as they can create dangerous fumes. Wait at least 24 hours after shocking before swimming.

    4. Staining Removers:

    • Formulations: These come in various forms depending on the type of stain. Common types include:
      • Metal Stain Removers: Often chelating agents that bind with metal ions, causing them to detach from the pool surface.
      • Rust Removers: Typically contain acidic solutions that dissolve rust stains.
      • Algae Stain Removers: May contain chlorine or oxygen-based bleach to remove discoloration caused by dead algae.
    • Effects on Pool Surfaces: Some stain removers, particularly those containing acid, can damage pool surfaces if not used properly. Always perform a spot test in an inconspicuous area first.
    • Combinations to Avoid: Never mix different stain removers, as it can create harmful fumes. Follow the manufacturer’s instructions for dilution and application.

    5. Enzyme Cleaners:

    • Formulations: These contain natural enzymes that break down organic materials like leaves, grass clippings, and swimmer waste. The enzymes target specific organic compounds, breaking them down into smaller particles easily captured by your pool filter.
    • Effects on Pool Surfaces: Generally safe for pool surfaces when used as directed.
    • Combinations to Avoid: Enzyme cleaners can be used alongside other pool chemicals, but avoid using them with shock treatments, as high chlorine levels can deactivate the enzymes.

Safety considerations

Before making your purchase, make sure that the cleaner liquid is safe for use in pools and will not damage surfaces or cause harm. Also, check that the product meets all safety standards set by local and national regulators.

Usage Frequency

Check the manufacturer’s recommendation for how often you need to use the pool cleaner. Some products are designed to be used daily or every few days to maintain the pool’s cleanliness, while other products may be designed for a deeper clean and may “shock” your pool if used too much, causing staining or a change in water color.

Effectiveness

As with anything else, products can vary in their effectiveness, so it’s crucial to consider what each pool cleaner can do to determine which one is the most cost-effective and suitable for your needs.

The Correct Way to Use a Pool Cleaner

When using a pool cleaner, it is crucial to pay attention to the dosage of the product. Make sure to follow the manufacturer guidelines to the letter, especially if you’re new to pool maintenance. Some pool cleaners also require diluting before adding to your pool water, so make sure to double-check if your pool cleaner needs dilution before turning the bottle upside down over your pool. After adding the cleaner, wait for the manufacturer-specified duration before running your filter or automatic pool cleaner.

Benefits of Using a Pool Cleaner

  1. Pool cleaners can quickly break down oils, grease, sweat, and other organic contaminants in pool water, helping maintain clear, healthy water for everyone to enjoy.
  2. It is an effective, economical, and safe way to keep your swimming area clean and sparkling.
  3. Most decent pool cleaners are designed to have a low-foaming action that will not leave behind residue or cloudiness.
  4. Pool cleaners provide superior spot cleaning for pesky algae spots that can be difficult to get rid of with other products.
  5. They are incredibly easy to use as they come ready mixed and ready to apply directly into your pool.

Pool Cleaner FAQs

How does a pool cleaner work?

A pool cleaner is formulated to help reduce bacteria and algae growth in swimming pools and to reduce time spent on cleaning the walls and floor of the pool. These liquids contain a variety of chemicals that help to sanitize your swimming pool. When these chemicals react with water, they form a solution that helps break down oils, grease, dirt, and other contaminants that can accumulate in your swimming pool.

What are some benefits of using a pool cleaner?

Using a pool cleaner can help reduce the amount of time spent cleaning your pool because these chemicals help break down dirt and debris more quickly than traditional methods like skimming or vacuuming alone can do. Plus, since you won’t have to spend as much time scrubbing surfaces by hand, you can spend more time enjoying your swimming pool rather than cleaning it. Also, when used properly, these solutions help keep water safe for swimming by killing bacteria and algae that can cause illnesses if ingested while swimming.

How often should I use a pool cleaner?

The frequency at which you should use pool cleaner liquids depends on several factors, including product guidelines, how often the pool is used, and the level of contamination present in the water. Generally speaking, most people find it beneficial to put in one dose every few weeks, but this could vary depending on individual circumstances. It’s always best to follow the instructions on the pool cleaner label, and if you're unsure or feeling out of your depth, it's not a bad idea to consult with a professional once.

Are there any safety precautions I should take when using pool cleaners?

Yes! Always follow the instructions provided by manufacturers carefully when using these products, as they contain potentially hazardous materials if not handled properly. Things like chlorine can be irritating to the skin and eyes, so proper care is crucial. Also, it’s essential to remember not to add too much product to the water at once, as this could lead to excessive foaming or staining. Also never mix different types of chemicals unless you're 100% sure of what you're doing or have received professional guidance.

Is there anything else I need besides pool cleaner?

Yes! You'll probably need some additional equipment, such as pool brushes and skimmers to do a thorough clean. If you can spend the $$$ and use your pool very often, a robot pool cleaner can be a worthwhile investment to almost completely automate your pool cleaning routine.
