If your pool has turned green, brown, or developed stubborn stains that regular cleaning cannot fix, an acid wash may be exactly what it needs. South Scottsdale homeowners deal with intense sun, hard water, and high heat — all conditions that accelerate algae growth and calcium buildup on pool surfaces. Because of this, deep restoration treatments are sometimes the only way to bring a pool back to life.
An acid wash strips away the top layer of plaster, removing embedded algae, stains, and mineral deposits that brushing and chemicals simply cannot reach. Therefore, it is one of the most effective reset options for neglected or heavily stained pools. The results are dramatic — and the difference is immediately visible.
At Valley Pool Service, our experienced technicians serve South Scottsdale and surrounding East Valley communities. We assess every pool carefully before recommending treatment. If your pool qualifies for an acid wash, we will walk you through the entire process so you feel confident every step of the way.
What Is an Acid Wash and When Do You Need One?
An acid wash uses a diluted muriatic acid solution to clean the interior surface of a drained pool. The acid dissolves algae, staining, and mineral scale that have bonded to the plaster. It is a deep-clean treatment — not a routine maintenance step.
Most pools do not need an acid wash every year. However, certain conditions make it the right call. Knowing when to pursue this treatment can save your pool surface and your budget.
Signs Your Pool May Need an Acid Wash
- Persistent green or black algae that returns after chemical treatment
- Brown or rust-colored staining across the pool floor or walls
- Heavy calcium scale that brushing cannot remove
- A pool left unused for an extended period without maintenance
- Cloudy, discolored water that will not clear despite chemical balancing
If you recognize any of these signs, the smart move is a professional inspection. Our team will evaluate your pool’s condition and recommend the most effective and cost-efficient path forward.
Is an Acid Wash Right for Every Pool?
Not every pool is a good candidate. The plaster surface must have enough thickness remaining to withstand the acid wash process. Additionally, if your pool has been acid washed multiple times, a resurfacing project may be a better long-term solution.
Our technicians will inspect your plaster before recommending treatment. We want to give you honest options — not just a quick sale. Furthermore, we will explain the pros and cons of each approach so you can make an informed decision.
The Acid Wash Process: Step by Step
Understanding what happens during an acid wash helps homeowners feel prepared. The process is straightforward, but it requires skill and safety-conscious technique. Here is what to expect when our team arrives.
Step 1 — Draining the Pool
First, the pool must be fully drained. This step takes several hours depending on the pool size. Moreover, proper drainage is critical — water must be disposed of in a way that complies with local guidelines. Our team handles this carefully and efficiently.
Step 2 — Applying the Acid Solution
Next, our technicians apply a diluted muriatic acid solution to the pool surface in controlled sections. The acid is worked across the plaster using brushes, lifting stains and dissolving mineral buildup as it goes. Safety gear and precise technique are essential during this phase.
The acid is then neutralized with a soda ash solution. This stops the chemical reaction and protects the remaining plaster. As a result, the surface is left clean, bright, and ready for refilling.
Step 3 — Rinsing and Refilling
After neutralizing, the pool is thoroughly rinsed. Then, the refilling process begins. Once the pool reaches the proper water level, our technicians balance the water chemistry before the pool is safe to swim in again. This step is just as important as the wash itself.
Finally, we inspect the surface and equipment to confirm everything is in good working order. We do not consider the job done until your pool is clean, balanced, and swim-ready.
Why South Scottsdale Pools Need Extra Attention
South Scottsdale’s climate creates unique challenges for pool owners. The combination of extreme summer heat, low humidity, and hard municipal water accelerates algae growth and mineral scaling faster than many homeowners expect.
Hard water is especially common across the greater Scottsdale area. Over time, calcium and magnesium minerals bond to pool plaster and create rough, discolored surfaces. Meanwhile, UV exposure and heat make algae spores more aggressive — especially during monsoon season when debris and bacteria enter the water.
Comparing South Scottsdale to Nearby Communities
Homeowners in South Scottsdale face similar pool challenges as those in nearby Gilbert, Tempe, Chandler, and Mesa. However, South Scottsdale pools often sit in older neighborhoods with mature landscaping. Because of this, leaf debris and organic matter can contribute to faster staining and algae problems.
Our team regularly services pools throughout the East Valley. We understand the local water conditions and pool construction styles common to this region. Additionally, we stay current on best practices for Arizona’s unique desert climate.
Acid Wash vs. Chlorine Wash: Which Do You Need?
Homeowners sometimes ask about the difference between an acid wash and a chlorine wash. Both treatments involve draining the pool, but they target different problems. Understanding the distinction helps you choose the right solution.
A chlorine wash uses a concentrated chlorine solution to kill algae. It is effective for moderate algae outbreaks but does not remove mineral staining or calcium scale. On the other hand, an acid wash removes both biological growth and mineral deposits by dissolving the outermost layer of plaster.
In general, a chlorine wash is a lighter treatment. An acid wash is reserved for more severe cases where staining or buildup is deeply embedded. Our technicians will assess your pool and recommend the right treatment — no guesswork required.

Caring for Your Pool After an Acid Wash
An acid wash gives your pool a fresh start — but aftercare matters just as much. The steps you take in the weeks following treatment will determine how long your pool stays clean and bright. Here are a few practical tips to protect your newly washed surface.
Post-Acid Wash Tips for Homeowners
- Test your water chemistry weekly for the first month after the wash
- Keep your pH and alkalinity balanced to protect the plaster surface
- Run your filter consistently — especially during Arizona’s summer heat
- Brush the pool walls and floor regularly to prevent algae from taking hold again
- Schedule routine professional maintenance to catch problems early
Arizona’s hard water can cause calcium scale to return within months if water chemistry is not managed properly. Additionally, summer algae pressure is real — especially during monsoon season. Consistent maintenance is the best way to protect your acid-washed surface long term.

Frequently Asked Questions About Acid Washing
How often should I acid wash my pool?
Most pools benefit from an acid wash every five to seven years under normal conditions. However, pools that have been neglected or exposed to severe algae outbreaks may need treatment sooner. A professional inspection will help determine the right timing for your specific pool.
Does an acid wash damage the pool plaster?
An acid wash removes a very thin layer of plaster. Therefore, it is not something you want to do excessively. When performed correctly and at the right intervals, it is safe and effective. Our technicians assess plaster thickness before recommending the treatment.
How long does the acid wash process take?
The full process — draining, washing, neutralizing, rinsing, and refilling — typically takes one to two days. Refilling times vary based on pool size and water pressure. Your pool will need water balancing before it is safe to swim in after refilling.
Can I acid wash my own pool?
Muriatic acid is a hazardous chemical that requires proper handling, safety equipment, and neutralization technique. Improper application can damage your plaster, harm your equipment, or create safety risks. We strongly recommend hiring a qualified pool professional for this treatment.
Will an acid wash fix a green pool?
In many cases, yes. An acid wash is one of the most effective treatments for pools with embedded algae and heavy staining. However, if the algae growth is moderate, a chlorine wash or chemical treatment may be sufficient. Our team will recommend the right approach after inspecting your pool.
