If your pool walls are stained, discolored, or covered in stubborn algae, a professional acid wash may be exactly what you need. Over time, Arizona’s intense sun, hard water, and heavy pool use can leave your plaster looking dull, spotted, or green. The good news is that this problem is completely fixable.
Homeowners across Glendale and the surrounding area trust acid washing to restore their pools to a clean, bright finish. However, this is not a DIY project. It requires proper equipment, safety precautions, and hands-on experience to do it safely and correctly.
At Valley Pool Service, our technicians bring years of experience to every job. We serve Gilbert, Glendale, and communities throughout the East Valley. Therefore, we understand what Arizona pools go through and how to bring them back to life.
What Is an Acid Wash and When Do You Need One?
An acid wash is a deep-cleaning process that strips a thin layer of plaster from your pool’s surface. As a result, it removes deep stains, algae, and mineral deposits that regular brushing and chemicals cannot touch. It reveals fresh, clean plaster underneath.
However, because it removes a layer of plaster each time, it should not be done every year. Most pools only need an acid wash every few years, depending on condition and care. A professional inspection helps you decide if it is truly the right solution for your pool.
Signs Your Pool May Need an Acid Wash
Not every discolored pool needs an acid wash. However, certain signs point strongly in that direction. Here are some common indicators that it may be time:
- Persistent green or black algae that chemicals cannot fully eliminate
- Brown or rust-colored stains on the plaster walls and floor
- Calcium scale buildup that gives the surface a rough, chalky texture
- A pool that has been sitting unused for a season or longer
- Overall dull, dingy appearance even after regular cleaning
If your pool shows one or more of these signs, contact Valley Pool to schedule a professional assessment. We will inspect your pool and recommend the best path forward.
The Acid Wash Process Step by Step
Many homeowners are curious about what actually happens during an acid wash. The process involves several carefully controlled steps. Each one matters for safety and for the final result.
Draining the Pool
First, your pool must be completely drained. This is a critical step because the acid is applied directly to dry plaster. Additionally, our technicians check local regulations before draining, since Arizona has specific rules about where pool water can be discharged.
We handle this step carefully to protect your yard and surrounding landscaping. Furthermore, we monitor the drain to prevent issues with soil movement or water pooling in the wrong areas.
Applying the Acid Solution
Next, our technicians mix a diluted acid solution and apply it in sections across the pool surface. They scrub each section thoroughly before rinsing it away with water. This process removes stains and surface buildup efficiently.
Because the acid is powerful, our team uses full protective gear throughout the job. Meanwhile, we work in a controlled, methodical way to ensure even coverage across the entire surface. This attention to detail produces a consistent, clean result.
Neutralizing and Rinsing
After the acid does its work, we neutralize the surface with a soda ash solution. This step is essential for stopping the acid’s action and protecting the fresh plaster underneath. Then, we perform a thorough rinse of the entire pool.
Finally, the spent acid water must be neutralized before disposal. Our technicians follow proper protocols to handle this safely. We take this responsibility seriously on every job.
Why Acid Washing Is Common in Arizona
Arizona pool owners deal with unique challenges that make acid washing more relevant here than in many other states. The combination of hard water, extreme heat, and year-round pool use accelerates staining and scale buildup significantly.
Glendale, like Gilbert, Chandler, and Tempe, sits in a region with notoriously high mineral content in the water supply. As a result, calcium and magnesium deposits build up on plaster surfaces faster than in softer-water areas. Over time, these deposits can make even a well-maintained pool look worn and dingy.
Additionally, the intense Arizona sun accelerates algae growth during warm months. When algae gets deep into plaster pores, standard chemical treatments may not fully resolve it. Therefore, an acid wash becomes the most effective solution.
East Valley Pool Conditions We See Regularly
Our team services pools across the East Valley, including Gilbert, Mesa, Scottsdale, and Chandler. Because of this broad experience, we recognize the patterns that lead to plaster staining in this region. We know what to look for and how to address it efficiently.
Moreover, we understand how seasonal shifts in Arizona affect pool chemistry. Pool water that sits through a long summer without proper balance can develop serious staining fast. We help you stay ahead of these issues with regular maintenance and timely interventions.
Acid Wash vs. Drain and Clean: What Is the Difference?
Homeowners sometimes ask whether they need a full acid wash or just a basic drain and clean. These are two different services with different purposes. Understanding the distinction helps you make the right call for your pool.
A drain and clean involves draining the pool and scrubbing away loose debris, algae, and dirt without applying acid. On the other hand, an acid wash goes deeper by chemically removing stains and surface deposits embedded in the plaster itself.
For pools with mild buildup or a green water problem that has not fully penetrated the plaster, a drain and clean may be sufficient. However, for severe staining, deep algae, or long-neglected surfaces, an acid wash delivers far better results. Our technicians will honestly assess which service your pool actually needs.
How Often Should You Acid Wash Your Pool?
This is one of the most common questions we hear. The answer depends on your pool’s condition, your water chemistry habits, and how aggressively your water has stained the surface over time.
In general, most plaster pools can tolerate a limited number of acid washes over their lifespan. Each treatment removes a small layer of plaster, so doing it too frequently will shorten the life of your pool’s finish. A professional inspection helps determine the right timing.
Additionally, the best way to reduce how often you need an acid wash is to stay consistent with water chemistry maintenance. Balanced water prevents the mineral buildup and algae growth that make acid washing necessary in the first place. Regular service visits from our team can help you maintain that balance year-round.
Tips for Protecting Your Plaster After an Acid Wash
Once your pool has been acid washed and refilled, protecting that fresh surface should be your top priority. Here are some practical steps to extend the life of your newly cleaned plaster:
- Balance your water chemistry immediately after refilling to protect the fresh plaster surface
- Brush the pool walls and floor daily for the first week to remove plaster dust
- Run your filter continuously during the initial fill period to clear any particles
- Schedule regular water testing to catch imbalances before they cause new staining
- Avoid low pH levels, which are especially damaging to fresh plaster
Our team can walk you through a complete post-acid-wash care plan. We want your pool to stay clean and protected long after we complete the job.
Frequently Asked Questions About Acid Washing
How long does an acid wash take?
Most acid washes can be completed in a single day, depending on the pool’s size and condition. However, the refill process takes additional time. Your pool will typically be swim-ready within a few days after the service is complete.
Is an acid wash safe for my pool?
Yes, when performed correctly by experienced technicians, an acid wash is safe and effective. Furthermore, it is far better for your pool than leaving deep stains or algae untreated for an extended period. We use diluted solutions and follow careful procedures on every job.
Will an acid wash remove all stains?
An acid wash removes most mineral stains, algae stains, and surface discoloration effectively. However, some deep metal stains may require additional treatment. Our technicians will let you know what to expect before starting the job.
Can I acid wash my own pool?
We strongly advise against it. Acid washing involves hazardous chemicals that can cause serious injury if mishandled. Additionally, improper application can permanently damage your plaster. Always hire a qualified pool professional for this service.
