Pool Acid Wash in Sherman Oaks, CA

A pool acid wash in Sherman Oaks is worth doing when stains or scale cover sound plaster and gentler methods have not worked. The wash strips a thin skin of the surface to expose cleaner plaster underneath, so it is a tool to use sparingly, not a routine chore.

We are clear about the limits: we do not replaster or resurface, and we will not wash plaster that is too thin, cracked or delaminating to benefit.

Pool Acid Wash in Sherman Oaks: What Makes It Different

Much of Sherman Oaks went up during the postwar building boom. The city's historic survey highlights a Nagle, Varna and Sarah Avenue district of single-family homes built from the mid-1940s to the early 1960s, and a wave of hillside construction south of Ventura Boulevard in the 1950s and 1960s. (Source: LA City Planning, SurveyLA) The pools behind those houses may have been built or refinished at any point since, and the National Plasterers Council says plaster can last up to 20 years with proper care (Source: National Plasterers Council), so an older finish may be too thin for another wash.

Local water leaves its mark too. LADWP's Valley supplies averaged roughly 103 to 140 mg/L of hardness in 2025 (Source: LADWP), and as summer evaporation is replaced with fresh water, calcium concentrates and scale forms on plaster and tile.

Draining is regulated as well. Sherman Oaks is part of the City of Los Angeles, whose stormwater code lists dechlorinated or debrominated pool water as a conditionally exempt discharge and bars commercial and public pool filter backwash from the storm drain. (Source: Los Angeles Municipal Code) We plan the route and the dechlorination before the pump starts.

What's Included

Here is what a pool acid wash in Sherman Oaks involves, following our pool acid wash service page:

• Assessment. Stain type identified and plaster checked for thin spots, cracks and hollow areas.
• Drain plan. Discharge route and dechlorination set before any water moves.
• Wash and rinse. Diluted acid applied section by section, then rinse water neutralized before it is pumped out.
• Refill. The pool refilled promptly, the fresh water balanced and the surface brushed through its first weeks.

Hillside Pools, Water Rules and Timing

Hillside yards need extra planning. Hoses may have to run a long way to an approved discharge point, and a pool with a slope above it deserves a careful look at drainage and groundwater before the shell is left empty.

Supply rules matter as well, since every wash ends with a refill. The City of Los Angeles is in Phase 2 of its water conservation ordinance (Source: LADWP), well short of the Phase 5 stage at which LADWP's shortage plan prohibits filling pools. (Source: LADWP) We confirm the phase before scheduling a pool acid wash in Sherman Oaks.

If your water is simply old and hard, a drain and refill alone may be enough, with no acid involved. See every service we offer on the Pool Cleaning Los Angeles homepage.
