A pool acid wash in Arcadia is the right call when plaster is structurally sound but stained or crusted with scale that brushing and balanced water will not remove. We drain the pool, wash the surface with diluted acid a section at a time, neutralize the rinse water and refill with chemistry set for the local supply.
Since each wash takes off a thin skin of plaster, we recommend one only when it will help, and we do not replaster or resurface. For the full list of services, visit the Pool Cleaning Los Angeles homepage.
Pool Acid Wash in Arcadia: What Makes It Different
Arcadia relies almost exclusively on groundwater pumped from the Main San Gabriel and Raymond basins, and its 10 city wells deliver about 4.6 billion gallons a year. Its 2025 water quality report lists average hardness of 210 mg/L and total dissolved solids of 330 mg/L. (Source: City of Arcadia) Evaporation leaves those minerals behind and every top-off adds more, so rough white scale on plaster is a predictable result over the years.
The same report reminds residents that runoff entering the city's storm drain system flows to the ocean, carrying chemicals with it, which is why drained pool water and acid rinse water need a proper route. (Source: City of Arcadia) Arcadia also offers a rebate on new pool and spa covers for single-family residential water customers, as long as the cover fits the pool's shape and covers at least 85% of the water. (Source: City of Arcadia) A cover in use cuts the evaporation that concentrates minerals in the first place.

- Stain and plaster check. We confirm the plaster is sound and identify mineral, metal or organic staining before recommending acid.
- Drain planning. The water is dechlorinated where required and sent only where local discharge rules allow.
- Section-by-section wash. Diluted acid applied and rinsed promptly, wall by wall and across the floor.
- Neutralized rinse water. Treated before it leaves the pool, never sent to the gutter.
- Refill and start-up. Alkalinity and pH first, then calcium and chlorine brought up in steps, with brushing afterward.

Is an Acid Wash the Right Fix for Your Arcadia Pool?
A wash makes sense when:
- Scale covers the plaster itself, not only the waterline tile.
- Algae left gray or green blotches after a green pool cleanup.
- Mineral or leaf staining is widespread and in-water treatments have not moved it.
It does not make sense when plaster is thin, cracked, delaminating or rough down to the base coat, because washing removes material that surface cannot spare. That pool needs resurfacing, which is not work we do. If the tile line is the only problem, a tile and calcium cleaning is the lighter fix and keeps the pool full. We give you that answer before any pool acid wash in Arcadia is scheduled.
