The Best Acid Washing Service in San Diego

Restore your pool's beauty with deep surface treatment that removes years of buildup and staining

What is Acid Washing?

Acid washing is an intensive pool surface treatment that uses a diluted muriatic acid solution to strip away the top layer of plaster, removing deep-set stains, mineral deposits, and discoloration that regular cleaning cannot address.

Deep Surface Restoration

Unlike regular cleaning, acid washing chemically etches the pool surface to remove a microscopic layer of plaster. This process reveals fresh, clean plaster underneath and eliminates stains that have penetrated beyond the surface.

The treatment is particularly effective for plaster pools that have developed stubborn discoloration, calcium scaling, metal staining, or deep algae stains over years of use.

While powerful and effective, acid washing should only be performed by trained professionals as it involves hazardous chemicals and requires precise application techniques to avoid damaging pool surfaces.

When Do You Need Acid Washing?

1. Persistent Staining

Brown, green, or gray stains that won't respond to scrubbing, chemicals, or shock treatment. These stains have penetrated the plaster surface and require acid treatment to remove.

2. Calcium Scaling

White or gray crusty deposits along the waterline or on pool surfaces. Calcium buildup creates a rough texture and harbors algae growth if left untreated.

2. Severe Algae Damage

Black algae staining or deep-set green discoloration that remains after algae treatment. The staining has become permanent and embedded in the plaster.

4. Overall Dullness

Your pool has lost its bright, clean appearance and looks dingy or gray despite regular maintenance. Years of buildup have created a dull film over the surface.
