Maintaining the area around your pool is just as important as keeping the water clean and inviting. The concrete deck surrounding your pool is constantly exposed to sun, pool water, dirt, algae, and foot traffic, which can lead to discoloration, staining, and even slip hazards. Whether you’re a seasoned pool owner or have just installed your dream backyard oasis, knowing how to clean the concrete around your pool properly can extend its life and enhance your overall outdoor experience.
In this guide, we’ll walk you through the best cleaning solutions, tools, and techniques for keeping your poolside concrete spotless without damaging the surface or your pool equipment.
Understanding the Importance of Clean Pool Decking
Clean pool decks contribute to more than just aesthetics. A well-maintained poolside concrete surface:
- Prevents slipping and improves safety.
- Reduces the growth of mold, algae, and bacteria.
- Prolongs the lifespan of the concrete finish.
- Maintains property value and curb appeal.
Failure to clean your pool area regularly can lead to persistent stains, structural damage from salt buildup, and increased maintenance costs over time. Therefore, understanding what cleaning products and methods work best for your specific concrete type is crucial.
What Types of Concrete Are Used Around Pools?
Before diving into the cleaning process, it’s important to identify what kind of concrete or hardscape material you’re working with. Different finishes and coatings may require specialized care. The most common types include:
Smooth Trowel Finish
This is a standard concrete finish that’s easy to clean but may show dirt more easily than others. It’s popular for its affordability and durability.
Exposed Aggregate Concrete
This type features decorative stones or pebbles embedded in the surface, offering a textured and slip-resistant surface. However, the aggregates can be sensitive to acidic cleaners.
Stamped Concrete
Resembling stone, brick, or wood, stamped concrete is a popular decorative option. It’s typically sealed, so cleaners must be pH-neutral to preserve the sealant.
Concrete Pavers
Made of individual concrete slabs, these offer flexibility and are easy to clean. However, weeds can grow between the joints, requiring specialty treatments.
Knowing your concrete type protects your investment and ensures your cleaning methods won’t harm the surface.
When to Clean Your Pool Concrete
Cleaning the concrete around your pool should be part of a regular maintenance schedule. The frequency depends on several factors:
Geographical Location
Areas with high humidity and heavy tree coverage are prone to faster mold and algae growth, requiring more frequent cleaning.
Usage Frequency
If your pool sees daily use, foot traffic will introduce more sunscreen, oils, and debris to the surrounding deck, necessitating more cleaning.
Weather Conditions
Extended rainy seasons can trap moisture in the concrete, leading to persistent staining and mold growth, while sunny climates accelerate evaporation of chlorinated water, leaving behind salt deposits.
Regular cleanings should occur at least once a month, with more frequent spot cleaning as needed. Seasonal deep cleaning is recommended in spring and fall.
The Best Products to Clean Concrete Around Your Pool
Choosing the right cleaner is key to maintaining clean, safe, and beautiful pool decks. Here’s a breakdown of the most effective cleaning agents:
1. Mild Dish Soap and Water
Best for: Light cleaning and everyday maintenance
An inexpensive and safe option, mild dish soap—such as Dawn—mixed with warm water, can be used to clean light dirt and oils from foot traffic. This method is non-abrasive and pH-neutral, making it suitable for all concrete types.
2. Oxygen-Based Bleach
Best for: Removing algae, mildew, and organic stains
Oxygen bleach, as opposed to chlorine bleach, is safer for use around pools and plants. It effectively kills organic growth without damaging the finish of your concrete.
3. Muriatic Acid
Best for: Severe mineral buildup and deep stains
Also known as hydrochloric acid, muriatic acid is a potent cleaning agent for removing stubborn stains and salt deposits. However, it must be used with extreme caution: proper dilution (typically one part acid to ten parts water), ventilation, and protective gear are required. Always test on a small, inconspicuous area first and rinse thoroughly.
4. Commercial Concrete Cleaners
Best for: Targeted stain removal and convenience
Numerous specialized cleaners are formulated for pool decks and concrete hardscapes. Brands like Krud Kutter, Wet & Forget, and Zep offer products that combine degreasing, disinfecting, and stain removal properties.

A 1:1 solution of white vinegar and water can be used safely on sealed and unsealed concrete to remove mold, mildew, and even some stains. It’s environmentally friendly and requires no special tools.
Step-by-Step Guide to Cleaning Poolside Concrete
Step 1: Remove Debris
Before any cleaning solution is applied, sweep or blow away loose debris—leaves, twigs, sand, and dirt. For pavers, use a dry broom to remove grit from between the joints before scrubbing.
Step 2: Rinse the Area
Use a garden hose with a nozzle or pressure washer (on a low setting) to rinse the surface. This will prevent dirt from muddying up your cleaning solution.
Step 3: Apply Your Chosen Cleaner
Now apply your cleaner using a spray bottle or garden sprayer. Apply in manageable sections so the product doesn’t dry out too quickly in direct sunlight.
Step 4: Scrub with the Right Brush
Use a stiff-bristle brush or broom made of synthetic materials to scrub effectively without damaging your concrete. For textured surfaces like stamped concrete or exposed aggregate, opt for a medium-bristle brush.
Step 5: Let the Cleaner Sit
Allow the cleaning solution to work for 5 to 15 minutes—follow product instructions. This is especially important when tackling algae, mold, or mineral stains.
Step 6: Rinse Thoroughly
Use fresh water from a hose or pressure washer to rinse off all cleaning agents completely. Ensure no chemical residue remains, especially if swimming is allowed on the same day.
Step 7: Repeat If Necessary
Persistent stains might require a second cleaning attempt or the use of a stronger chemical, like diluted muriatic acid.
Cleaning Tips Based on Stain Types
Different stains develop on pool concrete due to various causes. Here’s a breakdown of the most common stains and how to remove them:
Algae and Mold Stains
- Begin with a vinegar-water or oxygen bleach solution.
- Apply and let sit for 10–15 minutes.
- Scrub in circular motions, as mold and algae have a tendency to embed into the surface.
- Repeat for persistent areas.
Oil and Grease Stains
Dish soap is perfect for breaking down oil from lotions or suntan creams. Alternatively, baking soda mixed into a paste and left to sit in the stain before scrubbing can be effective.
Mineral Deposits
White calcified buildup from evaporated water or calcium scaling from high mineral content needs acidic solutions. Muriatic acid (diluted) or commercial calcium removers like Leslie’s Acid Magic can tackle these effectively.
Organic Stains
Coffee spills, food stains, or dark water marks respond well to oxygen bleach. These cleaners work by oxidizing the stain, lifting it from the concrete pores.
The Most Common Cleaning Mistakes Pool Owners Make
Even experienced homeowners can fall into bad habits. Avoid these missteps:
Using Chlorinated Bleach on Sealed Concrete
Chlorine bleach breaks down sealer over time, leaving stamped or decorative concrete vulnerable to moisture and staining.
Not Diluting Acid Solutions Properly
Concentrated muriatic acid can etch and pock surfaces if not correctly diluted. It can also damage nearby plants or pool liners if not rinsed thoroughly.
Using a Pressure Washer Incorrectly
High pressure on delicate or older concrete can lead to surface erosion and cracks. Use caution, especially with exposed aggregate or stamped surfaces.
Leaving Poolsides Damp
After cleaning, damp areas become ideal breeding grounds for algae. Always allow full drying or use fans/sunlight to expedite drying.
Protecting Your Pool Area After Cleaning
- Apply a penetrating sealer every 1–2 years to unsealed concrete.
- Use pool-friendly deck coatings for enhanced protection.
- Place mats at pool exits to catch dripping water and foot traffic dirt.
- Regularly trim nearby vegetation to reduce leaf drop and root intrusion into pavers.

What are the safest cleaners to use on concrete around a pool?
For cleaning concrete around a pool, it’s important to use products that are both effective and safe for the surrounding environment, including nearby plants, pool water, and people. Mild dish soap mixed with water is a gentle and effective solution for regular cleaning. It does not contain harsh chemicals that can harm the area and is easy to rinse away without leaving harmful residues. Another safe option is a solution of white vinegar and water, which serves as a natural disinfectant and helps remove light stains and algae without damaging the concrete.
For tougher grime or buildup, consider using a mild detergent specifically designed for concrete or pH-neutral stone cleaners. These are formulated to be tough on dirt but gentle on the surface and surroundings. Always avoid chlorine, bleach, or acidic cleaners like muriatic acid near the pool deck unless properly diluted and rinsed, as they can damage the concrete and potentially contaminate the pool water if not used correctly. Ensuring that all cleaner residues are thoroughly rinsed away after use is key to maintaining a safe and clean concrete surface.
Can pressure washing damage my poolside concrete?
Pressure washing is an effective method for cleaning poolside concrete, but it must be used carefully to avoid causing damage. If the pressure is set too high, it can erode the surface of the concrete, create pitting, or even dislodge sealants and joints. Older or already cracked concrete is especially vulnerable to high-pressure damage. Using a pressure washer with adjustable settings and starting at a lower pressure is recommended, especially on textured or decorative concrete surfaces.
To minimize the risk, keep the nozzle at least 12 inches away from the surface and use a wide-angle spray tip. It’s also wise to test a small, inconspicuous area first before proceeding with the entire deck. After pressure washing, make sure to clean up the runoff properly to prevent dirt or cleaning solutions from being washed into the pool or landscaping. If you’re unsure about using a pressure washer yourself, hiring a professional with concrete cleaning experience is a good alternative.
How often should I clean the concrete around my pool?
The frequency of cleaning poolside concrete depends on several factors, including usage, climate, and surrounding vegetation. In general, a light cleaning with soapy water should be done at least once a month to maintain appearance and prevent buildup of dirt, oils, and algae. If the area is heavily used or shaded by trees, more frequent cleaning may be necessary to address leaves, pollen, and organic stains that can accumulate and discolor the surface.
For deeper cleaning, such as scrubbing with a brush or pressure washing, aim to do this two to four times a year. This helps remove ingrained dirt and maintain the structural integrity of the concrete. Regular maintenance also extends the life of any sealants applied to the concrete. Always inspect the deck after cleaning for cracks or wear, which could become slip hazards or allow water to seep into the sub-base, causing further damage over time.
Is it okay to use pool chemicals to clean the surrounding concrete?
While pool chemicals like chlorine tablets or algaecides can effectively kill algae and disinfect concrete surfaces, they are not the best option for regular cleaning and should be used with caution. High concentrations of chlorine can discolor or etch concrete, especially when left in contact for long periods or exposed to sunlight. If you choose to use pool chemicals for spot-cleaning algae or mold, dilute them appropriately and rinse the area thoroughly afterward to avoid chemical buildup and unintended damage to nearby plants or pool water.
Long-term reliance on pool chemicals for concrete cleaning can also lead to increased chloride exposure, which over time may corrode metal fixtures and degrade the concrete itself. It’s better to use cleaners designed for outdoor concrete, such as oxygen bleach or mild detergent solutions, which are safer and more appropriate for repeated use. If dealing with persistent algae stains, a diluted bleach or trichlor solution applied sparingly and rinsed well can still be an option, but always test on a small area first and protect the pool’s water chemistry.
What natural alternatives are there for cleaning concrete pool decks?
Many homeowners prefer to use natural alternatives to clean concrete around their pool to reduce the environmental impact and avoid harsh chemical exposure. A popular choice is a mixture of white vinegar and water, which acts as a natural disinfectant and can dissolve light mold, mildew, and dirt without damaging the concrete. Baking soda can be used in combination with vinegar or alone as a scrubbing agent, especially on tougher stains or grease spots, helping to lift grime without leaving behind toxic residue.
Another natural option is using oxygen bleach instead of chlorine bleach. Oxygen bleach is biodegradable and far less harmful to plants, pool surfaces, and skin contact. Diluted lemon juice or citric acid can also break down some stains and provide a fresh scent without harsh odors. These natural cleaners are perfect for light to moderate cleaning and are safe for use around children and pets. However, for severe mold or heavy buildup, a more aggressive eco-friendly commercial concrete cleaner may be needed for a deeper clean.
Do I need to seal my poolside concrete after cleaning?
Sealing poolside concrete after cleaning is not always required, but it is highly recommended to protect the surface from water penetration, staining, and wear. A good concrete sealer can help repel oil, dirt, and pool chemicals, making future cleanings easier and prolonging the life of the concrete. Sealers also enhance the appearance by adding a subtle sheen or deepening the color, depending on the type chosen. Before sealing, ensure the concrete is completely clean and allowed to dry for at least 24 to 48 hours.
There are two main types of concrete sealers: penetrating sealers and film-forming sealers. Penetrating sealers soak into the concrete and offer long-term protection without altering the surface appearance significantly. Film-forming sealers, such as acrylics or epoxies, create a protective coat on the surface but may require more frequent reapplication, especially in high-traffic areas. Choose a non-slip sealer to maintain safety when the surface is wet. Sealing should be done every few years, depending on the wear and exposure of the concrete, and always follow the manufacturer’s instructions for best results.
What should I avoid when cleaning concrete near my pool?
When cleaning concrete around a pool, avoid using overly strong acidic cleaners like muriatic acid, unless absolutely necessary and used with extreme caution. These acids can etch the concrete, damage nearby vegetation, and splash into the pool, affecting water balance and potentially corroding pool equipment. Similarly, avoid using cleaners that contain phosphates or surfactants that can runoff into the pool and cause foaming or algae growth. Never mix different chemicals together unless directed by the product label, as this can create dangerous fumes or reduce effectiveness.
Additionally, avoid scrubbing with overly abrasive tools like wire brushes or harsh scouring pads, as they can scratch or wear down the concrete surface, especially if it is sealed or stained. Do not let cleaning solutions dry on the concrete surface, as they may leave unsightly residues or become more difficult to rinse away. Finally, avoid neglecting cracks and joints during the cleaning process—debris in these areas can trap moisture and lead to mold formation or freeze-thaw damage. Always focus on thorough rinsing and proper disposal of wastewater to protect the surrounding environment.
