If your pool has turned a murky shade of green or the surface looks stained and dull, a chemical wash may be exactly what it needs. This powerful cleaning process removes algae, mineral deposits, and deep-set stains that a standard brushing and shock treatment simply cannot reach. As a result, your pool can look and feel brand new again.
Tempe homeowners deal with intense sun, high temperatures, and hard water conditions that take a serious toll on pool surfaces. Because of this, algae blooms and calcium scaling are common problems throughout the East Valley. Fortunately, a professional chemical wash tackles these issues at the source.
At Valley Pool Service, we work with residential pool owners across Tempe, Gilbert, Chandler, and Mesa to restore pools that have been neglected or overwhelmed by Arizona’s climate. Our experienced technicians know exactly what your pool surface needs and how to treat it safely and effectively.
What Is a Chemical Wash?
A chemical wash is a deep-cleaning treatment applied directly to your pool’s plaster or surface. First, the pool is drained completely. Then, a diluted acid solution is carefully applied to strip away algae, staining, and mineral buildup from the surface walls and floor.
This process goes much deeper than a simple acid wash or standard cleaning. It removes layers of contamination that have bonded to the plaster over time. However, it also removes a thin layer of plaster, so it should only be performed when necessary and by a trained professional.
When Does a Pool Need a Chemical Wash?
Not every dirty pool needs a chemical wash. However, there are clear signs that indicate it may be the right solution. Look for these common warning signs:
- Persistent green or black algae that returns even after shocking
- Heavy staining from minerals, metals, or organic debris
- Rough or discolored plaster that feels gritty to the touch
- Long periods of neglect where the pool sat without treatment
- Chlorine-resistant algae that cannot be cleared through normal maintenance
If your pool checks one or more of these boxes, contact the Valley Pool team to schedule a professional inspection. We will assess your pool’s condition and recommend the best course of action.
Chemical Wash vs. Acid Wash: What’s the Difference?
Many homeowners use these terms interchangeably, but they are slightly different processes. An acid wash typically uses a stronger concentration and is applied to pools with more severe staining or algae infiltration. A chemical wash uses a milder dilution and works well for moderate buildup and surface discoloration.
Both methods require draining the pool and applying a chemical solution to the surface. Additionally, both require professional handling because the chemicals involved are hazardous. On the other hand, attempting either process without training can damage your plaster or create safety risks.
Why Professional Application Matters
Applying acid to a pool surface is not a DIY-friendly task. The solution must be evenly distributed and neutralized properly. Furthermore, the timing of each step matters greatly. Too long on one section can etch the plaster unevenly and create permanent damage.
Our Valley Pool technicians are trained to handle this process safely and efficiently. We use the right dilution for your pool’s specific surface type and condition. Moreover, we neutralize and properly dispose of all waste water in compliance with local regulations.
The Chemical Wash Process Step by Step
Understanding what happens during a chemical wash helps you know what to expect. Here is a general overview of how our team approaches the process:
Step 1: Drain the Pool
First, we fully drain your pool using a submersible pump. This step takes several hours depending on pool size. Meanwhile, we inspect the surface for cracks, chips, or other damage that may need repair before treatment begins.
Step 2: Apply the Chemical Solution
Next, our technician applies a diluted acid solution to the pool walls and floor in sections. The solution is scrubbed into the surface to break down algae roots, mineral deposits, and staining. Then, it is rinsed away carefully and collected at the drain.
Step 3: Neutralize and Rinse
After the chemical application, we neutralize the remaining acid using a soda ash solution. This step is critical. It stops the chemical reaction and protects the plaster from over-etching. Finally, the pool floor is thoroughly rinsed and inspected.
Step 4: Refill and Balance
Once the surface is clean and dry, we refill the pool with fresh water. After refilling, we balance the water chemistry to protect your newly cleaned surface and ensure it is safe for swimming. This includes adjusting pH, alkalinity, calcium hardness, and sanitizer levels.
Why Tempe Pool Owners Need This Service
Tempe’s climate creates some of the most demanding conditions for residential pools in Arizona. High summer temperatures accelerate algae growth. Additionally, the region’s hard water leads to calcium scaling that clouds pool surfaces over time.
Furthermore, many Tempe neighborhoods have mature trees that drop debris into pools frequently. Organic matter like leaves and algae can stain plaster deeply if left untreated for extended periods. Because of this, periodic deep cleaning is essential for maintaining a healthy pool surface.
Valley Pool Service also proudly serves pool owners in nearby communities including Gilbert, Chandler, Mesa, and Scottsdale. No matter where you are in the East Valley, our team is ready to help restore your pool to its best condition.
Protecting Your Pool Investment
A pool is a major investment, and the surface is one of its most important components. Neglecting staining or algae buildup shortens the life of your plaster significantly. Therefore, a timely chemical wash can actually save you money by extending the years before a full replaster is needed.
Moreover, a clean pool surface is easier to maintain going forward. Smooth, algae-free plaster is less hospitable to future algae growth. As a result, you may find that your routine maintenance becomes simpler and less expensive after a professional deep clean.
How to Prepare for a Chemical Wash Appointment
There are a few simple steps you can take before our team arrives. First, remove all pool toys, floats, and accessories from the water. Also, make sure there is clear access to your pool equipment and electrical shutoffs so we can work safely and efficiently.
Additionally, plan for your pool to be out of use for a couple of days during and after the process. The refill and balancing period requires time for the water chemistry to stabilize. However, once it is ready, your pool will be cleaner and clearer than it has been in a long time.

Frequently Asked Questions About Chemical Wash Services
How long does a chemical wash take?
Most chemical wash appointments take one to two days from start to finish. The draining, treatment, and rinsing typically happen on the first day. Then, the pool is refilled and balanced on the second day before it is swim-ready again.
Will a chemical wash damage my pool surface?
When performed correctly by a trained professional, the process is safe for most plaster surfaces. However, it does remove a thin layer of plaster. Therefore, it is not recommended more frequently than necessary. Our team will evaluate your surface before recommending this treatment.
How much does a chemical wash cost in Tempe AZ?
Costs vary depending on pool size, surface condition, and the extent of algae or staining. We recommend requesting a quote so our team can assess your specific situation and give you an accurate estimate. There is no one-size-fits-all price for this service.
Can I do a chemical wash myself?
We strongly advise against it. The chemicals involved are hazardous and require proper handling, protective equipment, and disposal methods. Additionally, improper application can permanently damage your pool’s plaster. Professional service protects both your safety and your pool.
How often should I get a chemical wash?
Most pools only need this service every few years, or when significant algae or staining has developed. Furthermore, keeping up with regular maintenance reduces how often a deep clean becomes necessary. Our team can set up a maintenance schedule that keeps your pool in great shape year-round.
