A pool acid wash in Glendale lifts stains that brushing and chemistry cannot reach: dark leaf tannins under the trees, gray and white scale from hard water, and blotches left behind after a green pool. The process is a drain, a sectioned wash with diluted acid, and a refill balanced from day one.
Because every wash removes a thin layer of plaster, we recommend one only when the surface is sound and the stains will not respond to anything gentler. We do not replaster or resurface pools, and if your finish is past washing, we will tell you so.
Pool Acid Wash in Glendale: What Makes It Different
Glendale pools pick up stains from two directions. Overhead, the city protects coast live oaks, valley oaks, sycamores and California bays (Source: Glendale Public Works Forestry), and leaves left on the floor for weeks leave brown tannin marks. Underfoot, the water is hard: GWP's 2025 report lists 350 ppm of hardness from the city's own treatment plant and an average of 234 ppm from MWD's Weymouth plant. (Source: Glendale Water and Power)
Many neighborhoods are old enough that plaster history is a real question. Rossmoyne, Glendale's largest historic district, was developed beginning in 1923 and largely built out by 1950. (Source: City of Glendale) Around homes of that age, a pool may have been added or refinished more than once, so we look closely at the surface before any acid touches it.
For the drain, we follow local discharge rules. Glendale Public Works says clean, dechlorinated pool water can go to the street, that water left without added chlorine will dechlorinate in the sun in 3 to 4 days, and that chlorinated or dirty water can go into the sewer cleanout. (Source: City of Glendale) Acid rinse water is neutralized before it goes anywhere.
