Is an acid wash the right fix?
An acid wash strips a very thin layer of plaster to reveal a cleaner surface underneath. That makes it useful for some problems and wrong for others.
-
It can help with
- Algae stains left after a green pool cleanup
- Leaf, tannin and dirt stains
- Some mineral and scale stains on plaster
- A dull, dingy look on plaster that is still smooth
-
It will not fix
- Rough or etched plaster
- Flaking, hollow or delaminating areas
- Cracks or chips
- Pebble or quartz finishes, which usually need different cleaning
If the surface is worn out, see pool resurfacing.
Sometimes the water is the problem
Not every drain includes an acid wash. Pool water collects things that chemicals cannot remove, and after enough time the best fix is fresh water. Pros may recommend a drain and refill when:
- Stabilizer (cyanuric acid) is so high that chlorine stops working well
- Total dissolved solids or salt levels are far out of range
- Calcium hardness keeps causing scale
- A pool has sat untreated for months
Regular water testing helps spot these before a full drain is needed.
Why draining a Florida pool needs a pro
Much of Florida has a high water table, especially during the rainy season. An empty in-ground pool is a large, light shell sitting in wet ground, and groundwater pressure can push it upward or crack it. Pros reduce that risk by checking conditions before draining, using the hydrostatic relief valve in the main drain when the pool has one, discharging water where local rules allow, and keeping the pool empty only as long as the work requires.
Please do not drain a pool yourself without professional advice. Before work begins, confirm that the pro you hire holds the Florida license your job requires.
What the process usually looks like
Assess
Check the surface, stains, water table and equipment.
Drain
Pump the water out to an approved discharge point.
Wash
Apply a diluted acid solution in sections, scrub and rinse.
Neutralize
Neutralize and remove the rinse water safely.
Refill and start up
Refill and balance the new water carefully.
What affects the cost
- Pool size and the amount of surface to wash
- Staining, and whether more than one pass is needed
- Drain only or drain and wash
- Refill water and start-up chemicals
- Debris left in the pool before draining

Acid wash questions
How do I find a pool acid wash near me?
Send a request with your city, the type of stains and when the pool was last resurfaced if you know. Dominion Pool Pros passes it to an independent local pro who drains and acid washes pools in your area.
How much does a pool acid wash cost?
It depends on pool size, how heavy the staining is, whether more than one wash pass is needed, the cost of refilling and start-up chemicals, and any cleanup of debris. A drain and refill without an acid wash costs less. Ask what is included.
How often can a pool be acid washed?
Not often. Each acid wash removes a thin layer of plaster, so repeated washes shorten the life of the surface. Many pros treat it as an occasional refresh, not routine maintenance.
Is it safe to drain a pool in Florida?
It can be, but it needs care. In areas with a high water table, an empty pool can be pushed upward by groundwater pressure. Pros check conditions, use the hydrostatic relief valve if the pool has one, and avoid leaving a pool empty longer than necessary. This is a big reason to have a pro handle draining.
Will an acid wash fix rough plaster?
No. An acid wash brightens stained plaster that is still sound. It will not fix roughness, delamination or cracks. Those need resurfacing.
