Acid Wash

A pool acid wash is a deep cleaning process used to remove stains, algae buildup, and discoloration from a pool's surface, typically made of plaster or Pebble Tec. It involves draining the pool and applying a mixture of muriatic acid and water to the interior surface to strip away a thin layer of material, revealing a fresh, clean layer underneath.

When Is an Acid Wash Needed?

A pool acid wash is recommended when:

• The pool has excessive algae growth that regular cleaning can’t remove.

• The water has been stagnant for an extended period, leading to stubborn stains.

• There is significant calcium buildup or mineral deposits on the surface.

• The pool surface has developed discoloration from chemicals or organic debris.

How Is It Done?

1. Drain the Pool – The pool must be completely emptied.

2. Apply the Acid Solution – A diluted muriatic acid solution is carefully applied to the walls and floor.

3. Scrub the Surface – The acid is scrubbed into the surface to remove stains and buildup.

4. Neutralize the Acid – Baking soda or soda ash is used to neutralize any remaining acid.

5. Rinse and Refill – The pool is thoroughly rinsed before refilling with fresh water.

Important Considerations

• Acid washing should be performed by professionals to ensure safety and prevent damage to the pool surface.

• It should not be done too frequently, as it wears down the pool plaster over time.

• Proper protective gear and ventilation are essential due to the strong fumes from the acid.
