Your pool’s tile and plaster take a beating in the Arizona heat. Over time, calcium deposits, algae stains, and mineral buildup can make even a well-maintained pool look dull and dingy. Acid washing tile is one of the most effective ways to restore your pool’s appearance and protect its surfaces for the long term.
Many Gilbert homeowners are surprised by how dramatically this service transforms their pool. Furthermore, it is not just about looks. Buildup on tile and plaster can affect water chemistry and shorten the life of your pool surfaces. Therefore, addressing it sooner rather than later is always the smarter move.
In this guide, we will walk you through exactly what to expect from acid washing and tile cleaning, why it matters in the East Valley climate, and how to know when your pool needs it. Additionally, we will answer the most common questions homeowners ask before scheduling this service.
What Is Acid Washing and Why Does It Matter?
Acid washing is a deep-cleaning process that removes stubborn stains, algae, and mineral deposits from your pool’s plaster or surface. Technicians apply a diluted acid solution directly to the pool walls and floor. This strips away a thin layer of plaster along with any embedded contaminants.
However, acid washing is not a routine maintenance step. It is a more aggressive treatment reserved for pools with serious discoloration or buildup. Because of this, it should be performed by an experienced professional who understands the correct dilution ratios and safety procedures.
In Gilbert and across the East Valley, hard water is a major factor. Our tap water naturally carries high levels of calcium and magnesium. As a result, mineral scaling builds up faster here than in many other parts of the country. That makes acid washing a particularly valuable service for local pool owners.
Acid Washing vs. Chlorine Washing
Many homeowners confuse acid washing with chlorine washing, but they serve different purposes. Chlorine washing is a gentler treatment used for moderate algae blooms. On the other hand, acid washing is needed when stains are deeply embedded or when the pool has gone green and been neglected for an extended period.
A professional inspection will help determine which treatment is right for your pool. At Valley Pool Service, our technicians will evaluate your surface condition and recommend the best option for your situation.
What Is Tile Cleaning and How Does It Work?
Tile cleaning targets the waterline tiles specifically. This is the band of tile that runs along the top edge of your pool, right at the water’s surface. Over time, oils, calcium, and mineral deposits build up along this line and create a white or gray crust that is difficult to remove with standard brushing.
Professional tile cleaning uses specialized tools and solutions to break down and remove that buildup. Additionally, some technicians use bead blasting or pressure washing techniques for more severe cases. The result is a clean, bright waterline that makes your entire pool look refreshed.
Why Gilbert Pools Need Tile Cleaning More Often
Gilbert sits in one of the hardest water regions in Arizona. The minerals dissolved in our water leave behind heavy calcium scaling, especially at the waterline. Moreover, the intense summer sun speeds up evaporation, which concentrates those minerals even faster.
Homeowners in communities like Chandler, Mesa, and Queen Creek face the same challenge. Therefore, regular tile cleaning is not a luxury in the East Valley — it is a necessary part of pool care. Most pool surfaces benefit from professional tile cleaning at least once a year, though some pools may need it more frequently depending on water chemistry and usage.
Signs Your Pool Needs Acid Washing or Tile Cleaning
Not sure if your pool is ready for this service? There are several clear warning signs to watch for. First, look at your waterline tile. If you see a thick white or gray crust that does not come off with a brush, that is calcium scaling.
Next, look at your pool floor and walls. Staining that ranges from light brown to dark green or black often signals embedded algae or mineral deposits. Finally, if your pool has turned completely green and a standard shock treatment has not fully cleared it, acid washing may be the most effective solution.
- Heavy calcium or mineral deposits on waterline tile
- Stubborn staining on plaster that does not respond to brushing
- Persistent green or black algae after chemical treatment
- Discolored or dull plaster that has lost its brightness
- A pool that has been left unused or unmaintained for a season
If you are noticing any of these signs, it is a good idea to schedule a professional evaluation before the problem gets worse. Early treatment is almost always less involved and more cost-effective than waiting.
The Acid Washing Process: Step by Step
Understanding the process helps you prepare and set realistic expectations. Here is what typically happens during a professional acid washing service.
Step 1: Drain the Pool
The pool must be fully drained before acid washing begins. This is a significant step that requires careful planning. In Arizona, draining a pool during peak summer heat can risk cracking or lifting the shell due to ground pressure and heat. Therefore, timing matters, and your technician will advise on the safest window for your pool.
Step 2: Apply the Acid Solution
Once drained, the technician applies a diluted muriatic acid solution to the pool surfaces. The acid is worked across the plaster in sections. It reacts with the surface and lifts stains, algae, and mineral deposits. Additionally, the technician will scrub the surface to help the solution penetrate stubborn areas.
Step 3: Neutralize and Rinse
After the acid has done its work, the technician neutralizes it with a soda ash solution. This step is critical for safety and for protecting the surrounding area. Then the entire pool is rinsed thoroughly. The wastewater must be disposed of properly according to local guidelines.
Step 4: Refill and Rebalance
Once the pool is clean, it is refilled with fresh water. However, the work is not finished there. New water needs to be fully balanced before the pool is safe to swim in. Your technician will test and adjust pH, alkalinity, calcium hardness, and sanitizer levels. This process may take a day or two to complete properly.
How Long Does Acid Washing Take?
The full process typically takes more than one day when you factor in draining, washing, and refilling. Most residential pools in Gilbert and surrounding areas like Tempe and Gilbert Ranch can expect the hands-on work to take several hours. Refilling and rebalancing adds additional time.
Plan accordingly if you have upcoming events or need the pool ready by a specific date. Talk with a pool care expert early so the schedule can be arranged to fit your needs. The team at Valley Pool Service will give you a clear timeline from start to finish.
Is Acid Washing Safe for Your Pool Surface?
When performed correctly, acid washing is safe and effective. However, it does remove a thin layer of plaster each time it is done. Therefore, it should not be performed too frequently. Most pools should only need this treatment every several years, depending on their condition and maintenance history.
Furthermore, older pools with thin or deteriorating plaster may not be good candidates for a full acid wash. In those cases, a gentler cleaning method or a plaster resurfacing may be a better long-term solution. A professional inspection will help you determine the right path forward.

Frequently Asked Questions About Acid Washing and Tile Cleaning
How do I know if my pool needs acid washing or just tile cleaning?
If the problem is limited to the waterline tile, tile cleaning is usually sufficient. However, if your plaster is stained, discolored, or covered in algae, acid washing may also be needed. A professional inspection will give you a clear answer.
Can I acid wash my own pool?
Technically, it is possible, but it is not recommended. Muriatic acid is a hazardous chemical that requires proper handling, protective equipment, and disposal methods. Mistakes can damage your pool surface or harm the surrounding area. Additionally, improper neutralization can create safety risks. Always use a trained professional for this service.
How often should Gilbert pool owners schedule tile cleaning?
Most East Valley pools benefit from professional tile cleaning once a year. Moreover, pools with harder water or heavier use may need it more frequently. Your technician can recommend a schedule based on your specific pool and water chemistry.
Will acid washing fix my green pool?
Acid washing can remove embedded algae from pool surfaces. However, it must be combined with proper chemical treatment and filtration to fully resolve a green pool situation. In many cases, a green-to-clean treatment is performed alongside or before acid washing for the best results.
Does acid washing affect the pool equipment?
The pool is drained before acid washing begins, so the equipment is not directly exposed to the acid. However, your technician will take precautions to protect the area around fittings and drains. After refilling, the equipment should be inspected to confirm everything is functioning properly.
