What Is Acid Washing?
Acid washing is a deep-cleaning process that uses a diluted muriatic acid solution to strip away a thin layer of your pool’s surface, usually plaster or inground concrete. This method is one of the most effective ways to remove stubborn pool stains, algae buildup, calcium deposits, and mineral stains from hard water or metals.
By breaking down these layers, acid washing restores your swimming pool’s surface to a brighter, cleaner, and more polished appearance. Whether your pool walls, bottom, or tile have lost their shine, or regular cleaning just isn’t enough, an acid wash could be the reset your pool needs.
When Does a Pool Need an Acid Wash?
Not sure if your Hilton Head swimming pool is ready for an acid washing? Keep an eye out for these signs:

- White calcium or mineral deposits on tile, plaster, or other pool surfaces
- Green pool water from long-standing algae growth
- Dull or faded plaster pool appearance even after cleaning
- A pool that’s been sitting drained or with stagnant water for too long

Frequently Asked Questions
How long does a pool acid wash take?
Most acid washing projects can be completed in a single day, depending on the pool’s size and condition.
How often should a pool be acid washed?
Typically, every 3–5 years, depending on usage, water chemistry, and staining severity. Overuse can wear down the pool’s surface, so it’s best done only when needed.
How often should I have my pool acid washed?
For most plaster or inground concrete pools, an acid wash is only needed every 5–7 years, or when stains and buildup can’t be removed through regular maintenance.
Will acid washing damage my pool surface?
When done by trained professionals, acid washing removes only a thin layer of plaster or concrete without harming the structural integrity of the pool.
Can acid washing be done on all types of pools?
It’s ideal for plaster, gunite, or inground concrete pools. Vinyl and fiberglass pools should not be acid washed.
