Acid Wash Pool Service: Charleston, SC

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, typically plaster or concrete. It’s one of the most effective ways to remove tough pool stains, including algae growth, calcium deposits, and mineral stains caused by hard water or metals.

The process targets areas where regular pool cleaning just doesn’t cut it, restoring your swimming pool to a cleaner, brighter, and more pristine condition. So, if your pool bottom, walls, or tile have lost their luster and you’ve tried scrubbing with little success, an acid wash might be the solution your pool needs.

  • Stubborn stains on the pool surface that won’t lift with brushing
  • Visible calcium or mineral deposits along pool tile or plaster
  • Green pool appearance due to long-standing algae growth
  • Faded or dingy surface even after regular cleaning
  • The pool looks aged, neglected, or has sat with stagnant water for too long

If you notice any of these, an acid wash pool service could give your pool the reset it needs.

Frequently Asked Questions

Can I acid wash my pool myself?

It’s not recommended. Muriatic acid is dangerous to handle, and improper application can damage your pool plaster. Let our pros handle the process safely.

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.

Will acid washing remove all pool stains?

Most, yes, especially mineral stains, algae, and chlorine stains. However, deep etching or old surface damage may need resurfacing afterward.

Is acid washing safe for all pools?

It’s ideal for concrete or plaster pools. If you have a vinyl liner or fiberglass pool, we’ll help you explore safer cleaning process options.

How long does it take to acid wash a pool?

Usually 1–2 days, including draining, washing, refilling, and balancing the pool water.

What’s the difference between acid washing and chlorine washing?

Chlorine washes are gentler and primarily used to address algae growth or biofilm. Acid washes are stronger and designed to remove mineral buildup and restore surfaces.

Will I need to re-balance the pool afterward?

Yes. After an acid wash, we’ll help adjust your water chemistry so it’s swim-ready and safe.
