Pool Acid Wash in Hercules, CA

Remove tough stains, embedded algae, and mineral scale to restore your pool's bright, clean finish. Professional acid washing across Contra Costa County.

Stain & Mineral Removal

We safely strip away the stained, top layer of plaster, removing hard water scale, copper stains, and rust spots to reveal the fresh surface beneath.

Safe Pool Draining

We manage the complete draining process, using proper submersible pumps and monitoring hydrostatic pressure to ensure your pool shell remains safe.

Embedded Algae Eradication

For pools that have been neglected for a long time, algae can embed deep into the plaster. An acid wash removes these roots completely.

Controlled Acid Application

We mix the acid to the precise strength needed for your specific plaster condition, ensuring an even clean without causing excessive wear to the surface.

Neutralization & Cleanup

After the wash, we thoroughly neutralize the acid wastewater before pumping it out, ensuring safe, eco-friendly disposal.

Start-Up Chemical Balancing

Once the pool is refilled, we return to add the necessary startup chemicals, balancing the fresh water to protect your newly exposed plaster.

We use professional-grade muriatic acid for the washing process. The key to a successful acid wash is the dilution ratio; we mix the acid with water to the exact strength required to remove the stains without unnecessarily degrading the plaster.

To neutralize the wastewater safely before disposal, we use soda ash. This ensures the water pumped out of the pool is pH-neutral and safe for the environment and local drainage systems.

Restored plaster after a professional acid wash

We inspect the plaster to ensure it is thick enough to withstand an acid wash. If approved, we set up pumps to safely drain the pool over the course of a day.

Our technicians apply the diluted acid mixture evenly across the walls and floor, scrubbing away the stains, and then quickly rinsing it to prevent over-etching.

The acidic wastewater collects in the deep end, where we neutralize it with soda ash. Once it is pH-safe, we pump the remaining slurry out of the pool.

You begin refilling the pool with a hose. Once full, we return to add the initial startup chemicals, balancing the water to protect the fresh plaster surface.

Signs It Is Time for an Acid Wash

If your pool looks old and dirty no matter how much you brush, it might be time for a reset.

• The plaster has overall discoloration or mottling
• There are hard, rough mineral deposits on the floor and walls
• You have stubborn rust or copper stains that will not brush off
• The pool was left green and stagnant for an entire season
