Your pool looked great last fall. Now it’s a murky, stained mess. If you’re a Gilbert homeowner staring at a green or discolored pool, an acid wash may be exactly what it needs. This process removes stubborn stains, algae, and mineral buildup from your pool’s plaster surface.
However, acid washing is not a routine maintenance task. It is a more aggressive treatment that strips away a thin layer of plaster. Therefore, knowing when to use it — and when to skip it — can save you time and money.
In this guide, the Valley Pool Service team walks you through everything Gilbert pool owners should know about acid washing. We cover what it is, when it’s needed, what to expect, and how to protect your pool afterward.
What Is an Acid Wash?
An acid wash is a deep-cleaning treatment applied directly to your pool’s plaster surface. Technicians drain the pool completely and use a diluted acid solution to remove stains, algae, and mineral deposits. The process reveals fresh, clean plaster underneath.
Additionally, the treatment is effective against black algae, rust stains, and calcium scaling. These are problems that regular brushing and chemical treatments simply cannot fix. Because of this, many Gilbert homeowners turn to acid washing after a long season of neglect or a major algae outbreak.
How the Process Works
First, a technician drains your pool completely. Next, they apply the diluted acid solution in sections. The acid reacts with the plaster and lifts away embedded stains and growths. Then, the technician rinses each section thoroughly before moving on.
Finally, the pool is neutralized, rinsed again, and inspected before refilling begins. The entire process typically takes a day to complete, depending on the size and condition of your pool. Moreover, refilling and rebalancing the water chemistry adds additional time before swimming is safe.
When Does a Pool in Gilbert Need an Acid Wash?
Not every stained pool needs an acid wash. However, certain conditions make it the right call. Gilbert pools face intense heat and heavy sun exposure. Because of this, algae and mineral buildup tend to be more aggressive here than in cooler climates.
You may need an acid wash if your pool has any of the following issues:
- Persistent green or black algae that returns after chemical treatment
- Deep mineral or calcium staining on the plaster walls and floor
- Rust-colored stains from metal oxidation in the water
- A pool that has sat dormant for an extended period without maintenance
- Visible organic buildup that brushing and shocking cannot remove
On the other hand, if your pool is only mildly discolored or has light algae, a thorough chemical treatment may be enough. A professional inspection from the Valley Pool team can help you determine the right approach.
Green Pool vs. Acid Wash: What’s the Difference?
A green pool is often caused by algae. In many cases, a green-to-clean chemical treatment can restore clear water without draining the pool. Furthermore, this approach is less invasive and less costly than a full acid wash.
However, if algae has penetrated deep into your plaster or your pool has turned a dark, murky brown or black, an acid wash is likely the better solution. Also, if the plaster surface feels rough or slimy after chemical treatment, the staining has gone beyond what chemicals alone can address.
Is Acid Washing Safe for Your Pool’s Plaster?
Acid washing does remove a thin layer of plaster each time it is performed. Therefore, it should not be done every year as a routine cleaning method. Most pool professionals recommend acid washing only when it is truly necessary.
Moreover, plaster has a natural lifespan. Frequent acid washing accelerates wear and can shorten the time before a replaster is needed. A well-maintained pool may only need an acid wash once every several years, depending on use and local water conditions.
Arizona Water and Mineral Buildup
Gilbert and the broader East Valley deal with notoriously hard water. Hard water contains elevated levels of calcium and other minerals. Over time, these minerals deposit on your plaster and create a rough, chalky surface.
Because of this, Gilbert pool owners may notice mineral scaling faster than homeowners in other parts of the country. Additionally, pools in communities like Chandler, Mesa, and Queen Creek face similar water quality challenges. Proper water chemistry management is your best defense against early scaling and staining.
What to Expect During a Professional Acid Wash
When you schedule an acid wash with Valley Pool Service, our technicians arrive fully equipped and ready to work. We start by draining your pool safely and inspecting the plaster surface. This inspection helps us identify any cracks, chips, or damage that should be addressed before we proceed.
Next, we apply the acid solution carefully and methodically. We work in small sections to maintain control and ensure even coverage. Furthermore, we neutralize and rinse each section before moving to the next. Safety is a priority throughout the entire process.
After the Wash: Refilling and Rebalancing
After the acid wash is complete, we refill your pool with fresh water. Then, we carefully balance your water chemistry before anyone swims. This step is critical because freshly washed plaster can affect your pH and alkalinity levels.
Additionally, we inspect your equipment during the refill process. We check your pump, filter, and other components to make sure everything is in good working order. As a result, you get a clean pool and the peace of mind that your system is functioning properly.
How to Protect Your Pool After an Acid Wash
An acid wash gives your pool a fresh start. However, keeping it that way requires consistent care. Following a few simple practices will help your plaster stay clean and extend the time before another acid wash is needed.
- Maintain proper water chemistry with regular testing and balancing
- Brush your pool walls weekly to prevent algae from taking hold
- Keep your filter clean and running efficiently
- Shock your pool regularly, especially after heavy use or rain
- Schedule routine professional maintenance to catch problems early
In addition, managing your calcium hardness and total dissolved solids is especially important in Gilbert’s hard water environment. A Valley Pool technician can help you set up a maintenance schedule that fits your pool and your lifestyle.

Frequently Asked Questions About Acid Washing
How do I know if my pool needs an acid wash or just a chemical treatment?
If your pool has stubborn staining, persistent algae, or heavy mineral buildup that chemicals have not resolved, an acid wash is likely the right choice. However, a professional inspection will give you a clear answer. Our team can evaluate your pool and recommend the most effective solution.
How long does an acid wash take?
The wash itself typically takes a full day. Additionally, refilling and rebalancing the water adds more time. Plan for your pool to be out of service for a few days from start to finish, depending on your pool size and water source.
Will an acid wash damage my pool equipment?
A properly performed acid wash should not damage your equipment. Our technicians take care to protect your fittings, lights, and drain covers during the process. Moreover, we inspect your equipment before and after the wash to ensure everything is functioning correctly.
How often should I acid wash my pool?
Most pools only need an acid wash every several years. Frequent washing accelerates plaster wear. Therefore, consistent weekly maintenance is the best way to extend the time between washes and protect your investment.
Can I acid wash my own pool?
Technically, it is possible to do it yourself. However, acid washing involves hazardous chemicals and requires proper safety equipment and technique. As a result, most homeowners choose to hire a professional. The risk of injury or plaster damage is simply not worth it.
