Owning a swimming pool is a luxury that comes with responsibility. One of the most common issues pool owners face is buildup on the pool tiles above the water line—also known as the scum line or waterline buildup. Over time, calcium deposits, dirt, sunscreen oils, and other contaminants collect on this area, leaving your pool looking dull and uninviting.
At Clean and Co, we believe proper care and cleaning not only keep your pool sparkling but also extend the life of your tiles. In this detailed guide, we’ll cover how to clean pool tiles above the water line, why it matters, the best tools and cleaners to use, and tips to prevent future buildup.
Why Do Pool Tiles Above the Water Line Get Dirty?
Before jumping into how to clean pool tiles above water line, it’s important to understand what causes the buildup:
- Calcium Deposits
Hard water contains minerals like calcium and magnesium. When pool water evaporates, these minerals remain behind, forming white or grayish scale on the tile surface. - Body Oils, Sunscreens, and Lotions
Swimmers bring oils and sunscreens into the pool, which cling to tiles at the waterline. Over time, these create a greasy film. - Algae Growth
If your pool chemistry isn’t balanced, algae can stick to the tile surface, especially in sunny areas. - Environmental Factors
Dust, pollen, and debris from surrounding plants and wind can also stick to the waterline, making the tiles look dirty.
By cleaning regularly, you can prevent buildup and keep your pool looking brand new.
Tools and Supplies Needed to Clean Pool Tiles Above the Water Line
When tackling the job, having the right tools makes all the difference. Here’s what you’ll need:
- Soft scrub brush or pool tile brush (non-abrasive to avoid scratching tiles)
- Pumice stone (for stubborn calcium deposits)
- Pool tile cleaner (specially formulated for safe use)
- White vinegar or baking soda paste (eco-friendly DIY alternatives)
- Protective gloves and eyewear
- Bucket and sponge
- Garden hose for rinsing
At Clean and Co, we recommend using eco-friendly pool tile cleaners whenever possible, as they protect both your tiles and the environment.
Step-by-Step Guide: How to Clean Pool Tiles Above Water Line
Now let’s get into the process. Follow these steps for the best results:
1. Lower the Water Level
To properly access the tiles, lower your pool’s water level by a few inches. This ensures you can scrub the entire waterline area without constantly splashing.
2. Pre-Rinse the Tiles
Use a garden hose to rinse off loose dirt and debris. This step makes scrubbing easier and prevents scratching.
3. Apply Cleaner or DIY Solution
- For light buildup, mix equal parts water and white vinegar. Apply the solution to the tiles with a sponge.
- For moderate buildup, make a baking soda paste (3 parts baking soda, 1 part water) and spread it on the tiles.
- For heavy calcium deposits, use a professional pool tile cleaner recommended by Clean and Co.
4. Scrub Gently
Use a soft-bristled brush to scrub the tiles in circular motions. Avoid using metal brushes, which can damage tile surfaces.
5. Use a Pumice Stone for Stubborn Stains
For hard calcium scale, lightly rub a pumice stone on the area. Keep the stone and tile wet to prevent scratching.
6. Rinse Thoroughly
After scrubbing, rinse the tiles with fresh water. This removes cleaner residue and prevents streaking.
7. Repeat if Necessary
For tiles that haven’t been cleaned in years, you may need multiple rounds of scrubbing and rinsing.
Best Cleaners for Pool Tiles Above the Water Line
When learning how to clean pool tiles above water line, the right cleaner is crucial. Here are some top options:
- Vinegar – Natural, affordable, effective for mild buildup.
- Baking Soda Paste – Great for gentle scrubbing without scratching.

Preventing Future Buildup on Pool Tiles
Cleaning pool tiles is only half the battle—prevention is key. Here are tips from Clean and Co to keep your pool tiles sparkling longer:
- Maintain Proper Water Chemistry
Balance your pool’s pH (7.2–7.6) and alkalinity (80–120 ppm). Imbalanced water speeds up calcium scaling. - Regular Brushing
Brush your pool tiles weekly to prevent buildup from hardening. - Install a Pool Cover
A cover reduces debris, dust, and pollen entering the pool. - Control Calcium Hardness
Keep calcium hardness levels between 200–400 ppm. Too high leads to scaling; too low damages pool surfaces. - Schedule Professional Cleaning
For stubborn scale or commercial pools, Clean and Co offers professional pool tile cleaning services with safe and effective methods.
DIY vs. Professional Pool Tile Cleaning
You might be wondering if you should tackle tile cleaning yourself or hire professionals. Here’s a quick comparison:
| DIY Cleaning | Professional Cleaning |
| Affordable (vinegar, baking soda, brushes) | Higher cost but thorough |
| Great for light stains and maintenance | Best for heavy calcium deposits |
| Time-consuming if buildup is severe | Saves time, hassle, and ensures long-lasting results |
At Clean and Co, we often recommend a DIY routine for maintenance and professional cleaning once or twice a year for deep restoration.
Frequently Asked Questions (FAQs)
How often should I clean pool tiles above the water line?
We recommend cleaning pool tiles once a month to prevent calcium deposits from hardening.
Can I use household cleaners on pool tiles?
Avoid harsh chemicals like bleach or abrasive powders. They can damage your tiles and disrupt pool chemistry. Stick to vinegar, baking soda, or specialized pool tile cleaners.
What is the best tool for scrubbing pool tiles?
A soft nylon brush or a pumice stone (for calcium scale) works best. Avoid wire brushes.
Why do my pool tiles keep turning white?
White stains are usually calcium buildup caused by high water hardness or evaporation. Regular cleaning and balanced chemistry will minimize this.
Should I drain the pool to clean the tiles?
No, draining your entire pool is unnecessary. Just lower the water level slightly to expose the waterline area.
