Sparkling clean pool tiles not only enhance your swimming pool’s aesthetic appeal but also contribute to better water quality and extend your pool’s lifespan. When those once-pristine tiles become coated with calcium deposits, algae, or general grime, many pool owners assume that draining the pool is the only solution. The good news? It’s entirely possible—and preferable—to clean pool tile without draining your pool, saving you time, water, and money.
Draining your pool isn’t just a hassle—it can also be risky. Exposing your pool’s surface to air can cause damage, especially in older pools where the liner might crack or shift. Plus, refilling uses thousands of gallons of water and requires complete rebalancing of chemicals.
In this comprehensive guide, we’ll explore multiple effective methods to clean pool tiles while keeping the water in, addressing different types of buildup, and providing preventative measures to keep your tiles looking their best year-round.
Understanding Pool Tile Buildup
Types of Pool Tile Deposits
Before diving into cleaning methods, it’s important to understand what you’re dealing with. Different types of buildup require different cleaning approaches:
- Calcium Scale (Calcium Carbonate): Appears as a white, chalky substance and is common in areas with hard water. This typically forms at the waterline.
- Calcium Silicate: A grayish-white, extremely hard deposit that’s more difficult to remove than calcium carbonate. It usually indicates long-term buildup.
- Organic Matter: Including algae, oils, and dirt that create a slimy or sticky film on tiles, often appearing as brown or green residue.
- Salt Deposits: Common in saltwater pools, appearing as white crystalline buildup.
- Scum Line: A visible line of oils, lotions, and body products that accumulate at the waterline.
Why Cleaning Without Draining is Beneficial
There are several advantages to cleaning your pool tiles without draining:
- Conservation of water (thousands of gallons)
- Cost savings on water bills and chemicals
- Time efficiency compared to drain-and-refill
- Prevention of pool structure damage that can occur when pools are emptied
- Reduced chemical rebalancing needed after cleaning
Tools and Supplies You’ll Need
Before beginning your cleaning project, gather these essential tools:
- Pool tile brush or pumice stone
- Soft cloth or microfiber sponges
- Pool-safe tile cleaner (acid-based or enzyme-based)
- White vinegar
- Baking soda
- Muriatic acid (for stubborn calcium stains—use with extreme caution)
- Protective gloves, eyewear, and clothing
- Bucket
- Pool tile cleaner machine (optional for large jobs)
- Extension pole for hard-to-reach areas
How to Clean Pool Tiles Above the Water Line
The waterline is where most visible buildup occurs, and fortunately, these tiles are the easiest to clean without draining.
Method 1: Baking Soda Paste (For Light Buildup)
This gentle abrasive is excellent for light to moderate calcium deposits:
- Mix baking soda with water to create a thick paste
- Apply to tiles using a soft cloth or pool brush
- Scrub in circular motions, focusing on stained areas
- Rinse thoroughly with pool water
DIY Tip: Use an old toothbrush for tight spaces or decorative tile inlays.
Method 2: Vinegar Solution (For Mild Calcium Deposits)
Vinegar’s acidity makes it effective against mineral deposits:
- Mix equal parts white vinegar and water in a spray bottle
- Spray directly onto tile at the waterline
- Let sit for 10-15 minutes to break down deposits
- Scrub with a non-abrasive pool brush
- Rinse clean with pool water
Pro Tip: For stubborn areas, soak a towel in vinegar solution and press it against the tiles for 1-2 hours before scrubbing. Add a sprinkle of baking soda for extra cleaning power on tougher spots.
Method 3: Commercial Pool Tile Cleaners
For tougher deposits, specially formulated cleaners offer more powerful results:
- Choose a cleaner specifically designed for pool tiles (recommendations below)
- Apply according to manufacturer’s instructions
- Use appropriate scrubbing tools (soft brushes for glass tiles, more abrasive for concrete)
- Rinse thoroughly to prevent chemicals from affecting water balance
Best Options Include:
- CLR or Bio-Dex 300 for calcium buildup
- Tile Soap or enzyme-based cleaners for oils and grime
- Eco-friendly options with non-toxic or biodegradable formulations
Method 4: Pumice Stone (For Heavy Deposits)
If vinegar or commercial cleaners don’t cut it, try a pumice stone:
- Always keep the stone and tile wet during cleaning
- Gently rub the stone along the tile surface using light pressure
- Work in small sections and rinse frequently
- Finish with a quick clean using a soft cloth
Caution: Don’t use pumice stones on vinyl or fiberglass pools—they can scratch! Only use on ceramic or concrete tiles.
How to Clean Pool Tiles Below the Water Line
Cleaning tiles beneath the water surface presents a different challenge but is still achievable without draining.
Underwater Tile Cleaning Techniques
Method 1: Pool Vacuum and Brush Combination
- Use a pool vacuum brush attachment
- Methodically brush tile surfaces underwater
- Allow the vacuum to capture loosened debris
- For best results, perform during regular cleaning maintenance
Method 2: Underwater Hand Tools
For spot cleaning specific areas:
- Use a grout brush or dedicated pool tile cleaning tool
- Focus on visibly stained or algae-affected areas
- Work in small sections for thorough cleaning
- Vacuum pool afterward to remove dislodged debris
Method 3: Pool Tile Cleaning Machines
For more serious cleaning without draining:
- Rent or purchase a submersible pool tile cleaning machine
- Follow manufacturer instructions for underwater operation
- Use appropriate attachments for your specific tile type
- These machines often use pressurized water, soda blasting, or bead blasting to remove deposits quickly
Best for: Salt buildup, scale, or thick deposits that resist manual cleaning Types: Portable handheld units or professional-grade equipment
How to Clean Pool Tile with Muriatic Acid
Using Muriatic Acid Safely (For Extreme Cases Only)
Muriatic acid (diluted hydrochloric acid) is extremely effective but should be used as a last resort and with great caution:
- Safety First:
- Always wear chemical-resistant gloves, eye protection, and protective clothing
- Work in a well-ventilated area
- Have plenty of water nearby for rinsing
- Proper Dilution:
- Mix 1 part acid to 4-10 parts water (ALWAYS add acid to water, never water to acid)
- Mix in a plastic container, never metal
- Application:
- Apply only to tiles above waterline
- Use an acid-resistant brush with an extended handle
- Work in small sections (3-4 feet at a time)
- Limit contact time to 30-60 seconds
- Immediately rinse thoroughly with water
- After Treatment:
- Test pool water pH and adjust as needed, as acid runoff can affect water chemistry
- Neutralize any remaining acid with baking soda
Warning: Muriatic acid should be considered a last resort for extremely stubborn calcium deposits. It can damage tile finishes, grout, and pool equipment if used improperly.

Frequently Asked Questions
What is the best thing to clean pool tiles?
The best pool tile cleaner depends on the type of buildup:
- For light cleaning: Vinegar solution or baking soda paste
- For calcium deposits: CLR, Bio-Dex 300, or Scale Free
- For oil and grime: Tile Soap or enzyme-based cleaners
- For tough stains: Pumice stone (on appropriate surfaces)
For regular maintenance, a baking soda paste or vinegar solution works well for most situations. Commercial products provide stronger cleaning power for established deposits.
How do I clean the bottom of my pool without draining it?
To clean pool floor tiles without draining:
- Use an automatic pool vacuum designed for tile surfaces
- Deploy a manual pool vacuum with brush attachment
- Consider an underwater pool tile cleaning machine for stubborn areas
- For targeted cleaning, use a weighted pool brush with appropriate stiffness for your tile type
- For algae or sediment, robotic pool cleaners work well
Always vacuum the pool after cleaning to remove loosened debris.
Can you use vinegar to clean pool tile?
Yes, vinegar is an excellent natural option for cleaning pool tiles, especially for mild calcium buildup. Its acidity (about 5% acetic acid) helps dissolve mineral deposits without harsh chemicals. For best results:
- Use white vinegar (avoid colored vinegars that may stain)
- Apply directly or as a 50/50 solution with water
- Allow to sit 10-15 minutes before scrubbing
- Use on waterline tiles or with pool brushes underwater
- Pair with baking soda for extra cleaning power on tougher spots
Vinegar works particularly well for newer deposits and regular maintenance cleaning, and it’s eco-friendly and safe for pool water chemistry.
