Pool Acid Wash Phoenix, AZ
What Is Acid Washing?
Acid washing—sometimes referred to as “drain and clean”—is a deep cleaning method used to strip away a thin layer of the plaster surface, removing:
- Algae and organic stains
- Metal or mineral stains (copper, iron, manganese)
- Calcium buildup and scale
- Discoloration from leaves, debris, or neglect
- Yellowing, graying, or black streaks
- Bacterial or chemical imprints
- Residue left after a green pool recovery
The process involves draining the pool completely and applying a diluted muriatic acid solution to the interior surface, then scrubbing and rinsing thoroughly. The result is a bright, clean plaster finish that looks dramatically refreshed.
Signs Your Phoenix Pool Needs an Acid Wash
Not every pool needs an acid wash—but if your pool has gone without one for several years or has suffered from poor maintenance, it may be time.
You may need acid washing if you notice:
- Persistent discoloration that doesn’t respond to brushing or chemicals
- Calcium scale forming on walls or along the waterline
- Deep stains caused by algae blooms or organic matter
- Black algae spots or streaks that remain even after treatment
- A general “dingy” or uneven appearance in the plaster
- Pool water turning green more frequently due to lingering spores
- Your pool hasn’t been drained or cleaned in 5+ years
In Phoenix, where pools are exposed to high heat, UV rays, and hard water, surface buildup happens faster than in cooler climates. We recommend evaluating for an acid wash every 3–5 years depending on use and water quality.
Our Acid Washing Process
At Orange Tree Pool Service, we follow a careful, multi-step acid wash process to deliver top-tier results while protecting your plaster, plumbing, and environment.
1. Pool Drain and Inspection
We begin by draining the pool completely, removing debris, and inspecting the surface for cracks or plaster damage.
2. Surface Prep
We apply protective coatings where needed, block off sensitive features, and ensure all pump and filtration systems are secured before the acid application begins.
3. Acid Wash Application
We apply a controlled mixture of muriatic acid and water across the interior surface, allowing it to foam and react with built-up stains. This is followed by scrubbing and brushing to lift discoloration and residue.
4. Thorough Rinse and Neutralization
After the acid has done its job, we rinse the entire surface with a neutralizing solution (usually soda ash or a commercial neutralizer) to safely halt the acid’s action and prepare the pool for refilling.
5. Refill and Chemical Balance
Once the pool is clean and safe, we refill it and perform an initial chemical balancing to protect your newly exposed plaster and prevent future staining.
Safety First: Why DIY Acid Washing Is Risky
Muriatic acid is extremely corrosive and must be handled with precision and full protective equipment. Improper application can result in:
- Plaster damage or surface etching
- Burns or serious respiratory injuries
- Environmental contamination from improper disposal
- Equipment damage if acid gets into pipes or pumps
- Long-term damage to your pool finish
As licensed pool professionals, we ensure all safety protocols are followed, including proper chemical handling, local water disposal compliance, and post-wash equipment inspection. Letting a certified team handle your acid wash means better results and zero risk to your health or investment.
Acid Wash vs. Chlorine Wash: What’s the Difference?
If your pool has experienced a recent algae bloom or water contamination, you may be wondering whether you need an acid wash or a chlorine wash.
- Acid Wash is best for mineral stains, scale, and deep discoloration in plaster.
- Chlorine Wash is used primarily to sanitize the surface after organic contamination like algae, mold, or bacteria.
At Orange Tree Pool Service, we’ll inspect your pool and determine which method is appropriate—or whether a combination of both is needed.
How Often Should You Acid Wash a Pool in Phoenix?
Because acid washing removes a thin layer of plaster each time, it’s not a treatment to perform frequently. Most pools can handle 1 to 3 acid washes during their plaster lifespan (typically 10–15 years).
We recommend:
- Every 5–7 years for well-maintained pools with occasional staining
- Every 3–5 years for heavily used pools or those exposed to hard water
- After green pool recovery when residual stains remain
If your plaster is too thin, brittle, or cracking, we’ll recommend an alternative treatment—or guide you through options like pool resurfacing.
