Thinking about an acid wash pool in San Angelo?
If your San Angelo pool has stubborn stains, rough plaster, or surface etching after years of wear, you may have heard that an acid wash can make it look like new. Acid washing is a labor-intensive, aggressive surface treatment that removes a thin layer of plaster to eliminate mineral staining, embedded algae, or rust. It can be the right call — but only in the right situations. This guide explains when an acid wash helps, the risks, and what local homeowners should check before scheduling the job.
How acid washing works (quick)
An acid wash uses diluted muriatic acid and scrubbing to remove the top layer of plaster. It takes off surface stains and etching, but it also shortens the life of the plaster and isn’t a fix for structural problems, deep staining that has penetrated the surface, or recurring chemistry issues.
Quick Checklist — Inspect before you schedule
- Is staining only on the surface or deep & locked into the plaster?
- Are there cracks, delamination, or loose plaster? (That needs repair first.)
- Is your pool repeatedly green or cloudy despite proper chlorine and filtration?
- Have you tested and balanced calcium hardness and pH to rule out etching?
- Do you have a recent filter backwash, cartridge cleaning, or media change?
When an acid wash makes sense
Acid washing is useful when stains are limited to the surface and cosmetic improvement is the goal — for example, hard-water scale, light rust staining, or plaster that’s picked up years of discoloration. It’s also a common step before refinishing or applying new finishes.
When NOT to acid wash
- Structural damage, large cracks, or loose plaster — these require repair, not an acid wash.
- Recurring algae or chemistry problems — fix the equipment and water balance first.
- Newer pools where plaster life remains; acid washing shortens plaster lifespan.
When to DIY vs When to Call Us
DIY is reasonable for basic stain removal attempts (brushing, non-acid stain removers, using a pressure washer carefully) or for routine maintenance. But call Concho Valley Pool for an acid wash if:
- You’re unsure whether the stain is surface-level or structural.
- The pool is commercial, an HOA, apartment complex, or a large residential shell where safety and compliance matter.
- You need plaster repairs, deep cleaning, or a full resurfacing estimate.
Acid wash requires trained handling of hazardous chemicals, proper disposal, and careful neutralization procedures. For safety, longevity of your finish, and accurate diagnosis, let a local pro evaluate first.
