Acid Wash and Stain Removal

Is your pool looking dull and stained? Shark Swimming Pools offers professional acid wash and stain removal services to restore the beauty of your pool and remove tough stains caused by algae, minerals, and rust. Whether your pool surface has deep algae stains or stubborn scaling, our experienced team can help you bring back its shine.


What Is an Acid Wash?

An acid wash is a specialized process used to remove a thin layer of your pool’s plaster or concrete surface, eliminating stains and revealing clean, fresh material beneath. This method is highly effective for pools that have developed deep stains, mineral buildup, or a generally dull appearance.


When Does Your Pool Need an Acid Wash?

If your pool has tough stains that won’t come off with regular cleaning, it might be time for an acid wash. Here are some common signs:

  • Persistent algae stains: When brushing and chemicals aren’t enough, an acid wash can remove deep-set algae.
  • Mineral scaling: Calcium and other minerals can leave unsightly deposits on your pool walls, which acid washing can eliminate.
  • Rust stains: Acid washing is effective at removing rust stains caused by metal objects in or around your pool.
  • Dull or discolored surface: If your pool’s plaster has lost its shine, an acid wash can restore its original brightness.

The Acid Wash Process

Our five-step acid wash process ensures your pool is restored quickly and safely:

  1. Drain the Pool: We begin by safely draining your pool to access the surface.
  2. Inspect the Surface: We check for cracks or damage that might need repair before we begin the wash.
  3. Apply Acid Solution: Our technicians carefully apply a diluted acid solution to dissolve stains, algae, and scaling.
  4. Neutralize and Rinse: Once the wash is complete, we neutralize the acid to ensure no residue remains, and we thoroughly rinse the surface.
  5. Refill the Pool: After the process is finished, we refill your pool with fresh water and rebalance the chemicals.

Benefits of Acid Washing

An acid wash offers significant benefits that can enhance the look and longevity of your pool:

  • Removes Deep Stains: Acid washing is the most effective way to remove stubborn stains caused by algae, rust, and minerals.
  • Restores Pool Surface: The process reveals a fresh layer of plaster, bringing back the brightness and clean appearance of your pool.
  • Improves Water Quality: By eliminating mineral buildup, your pool water becomes easier to balance and maintain.
  • Prolongs Surface Life: Regular acid washing can help protect your pool’s surface from deeper damage, extending its life.
