Over time, swimming pools can develop stubborn stains, algae discoloration, calcium buildup, and dull surfaces that regular cleaning simply can’t remove. When your pool starts looking aged or neglected, professional acid washing can dramatically improve its appearance and restore a cleaner, brighter finish.

If your pool has lost its original shine, here’s what you should know about the acid washing process and when it may be the right solution.

What Is Pool Acid Washing?

Pool acid washing is a deep-cleaning process used primarily on plaster or concrete pools. The process involves draining the pool and applying a diluted acid solution to remove a thin layer of surface buildup, stains, and discoloration.

This treatment can eliminate:

• Algae staining
• Mineral and calcium deposits
• Rust stains
• Chemical discoloration
• General surface dullness

The result is a cleaner, fresher-looking pool surface.

Signs Your Pool May Need Acid Washing

You may benefit from professional acid washing if you notice:

• Persistent stains that brushing won’t remove
• Green or yellow discoloration from algae
• Rough or chalky pool surfaces
• Heavy calcium scaling around the waterline
• Cloudy or aged-looking plaster

Acid washing is especially common for older pools or pools recovering from severe algae problems.

Benefits of Acid Washing

Restores Appearance

Acid washing removes years of buildup and helps your pool regain a cleaner, brighter finish.

Improves Water Quality

By removing contaminants and algae residue, acid washing helps improve overall water clarity and sanitation.

Prepares Pools for Resurfacing

Many resurfacing projects begin with acid washing to properly prep the surface.

Extends Pool Enjoyment

A cleaner-looking pool creates a more inviting and enjoyable swimming environment.

Why Professional Service Matters

Acid washing is not a typical DIY project. Improper handling can damage your pool surface or create safety risks. Professional service ensures:

• Correct acid dilution and application
• Protection of plaster and pool materials
• Safe draining procedures
• Proper cleanup and neutralization
• Reduced risk of surface damage

At A&N Pool Solutions, we carefully evaluate your pool’s condition before recommending acid washing to ensure it’s the right solution.

How Often Should Acid Washing Be Done?

Because acid washing removes a small layer of plaster each time, it should only be performed when truly necessary. Most pools only need acid washing every few years, depending on maintenance, water chemistry, and environmental conditions.

Regular maintenance and balanced chemicals can help reduce how often this service is needed.
