What Is Acid Washing?
A pool acid wash is a deep cleaning method that uses a carefully diluted muriatic acid solution to remove a thin layer from the pool’s surface, typically plaster or inground concrete. This process lifts dirt stains, mineral deposits, calcium buildup, and algae growth that regular cleaning cannot fully remove.
The acid washing process requires draining the pool and applying the acid mixture in sections, then rinsing thoroughly before refilling. Our team handles the entire cleaning process safely and efficiently, so you do not have to worry about potential dangers tied to acid exposure or improper handling.
When Does a Pool Need an Acid Wash?
Many Greenville area pool owners wait too long before scheduling an acid wash. Knowing the signs helps you avoid larger issues later. Your pool may need an acid wash if you notice:
- Stubborn pool stains that do not clear up after brushing
- White calcium deposits or mineral buildup along the tile line or pool wall
- Algae stains that return even when water chemistry is balanced
- Dull or discolored pool surface despite regular maintenance
If your pool has been neglected for an extended period and has stagnant pool water, acid washing can help restore the surface. Pools that have sat empty or uncovered for months often benefit from this service before being put back into regular use.

The Acid Wash Process
Our Greenville team follows a careful process to deliver consistent results while protecting your pool surface. We start by draining the pool completely, then apply the diluted acid solution in sections to lift stains and buildup. Each section is scrubbed and rinsed before moving to the next area.
Once the entire surface has been treated, we rinse the pool thoroughly to remove all acid residue. After refilling, we balance the water chemistry so your pool is ready for use. We use professional-grade equipment and follow safety protocols throughout the job.

Frequently Asked Questions
How often should pools have an acid wash?
Most pools benefit from acid washing every three to five years. However, pools with heavy staining, frequent algae problems, or significant mineral deposits may need it sooner.
Is acid washing safe for my pool?
Yes, when performed by trained professionals. Our process protects your pool surface while thoroughly removing stains and buildup.
Will an acid wash remove all pool stains?
Acid washing removes most stains, including algae, calcium deposits, and mineral discoloration. However, some deep or older stains that have penetrated the plaster may need additional treatments.
How long does the acid wash process take?
The acid wash process can usually be completed within a single day, but the exact timeline will depend on the pool’s size and condition. Larger pools or those with heavy buildup may require additional time.
Can acid washing be done on all types of pools?
Acid washing is ideal for plaster, in-ground concrete, or gunite pools. This treatment should not be used on vinyl or fiberglass pools since the harsh chemicals can damage those surfaces.
