Pool Acid Washing in Thousand Oaks, CA

What Acid Washing Does

Over the years, plaster pool surfaces collect stains from minerals, metals, leaves and algae. Some stains respond to brushing and chemical treatment, but others are set deep in the surface. Acid washing removes a very thin layer of plaster, taking many of those stains with it and revealing a cleaner surface underneath.

Acid washing is often used after a pool has been left green for a long time, when stains have built up over many seasons or when a homeowner wants to refresh the look of an older plaster finish before deciding on resurfacing. For many pools it is a practical middle step that improves appearance without the time and cost of a full replaster.

The Acid Wash Process

A typical acid wash includes:

Inspecting the plaster to confirm acid washing is a good fit
Draining the pool safely
Cleaning out debris and sediment
Applying a diluted acid solution to the surface in sections
Rinsing thoroughly and neutralizing the residue
Refilling the pool
Balancing the new water and restarting the equipment

Is Acid Washing Right for Your Pool?

Acid washing is not the right choice for every pool. Because it removes a layer of plaster, it should not be done too often, and it is not suitable for every surface type. Thin, worn or damaged plaster may be better served by other options. We look at the condition of your surface and explain what results are realistic.

After the wash, keeping the water balanced is important to protect the fresh surface and prevent new stains. With 20 years of experience caring for pools, we can handle the acid wash and continue with regular service to keep your pool looking its best.
