Over time pools develop stains. At a certain point you may consider acid washing your pool to freshen up your surface. Traditional acid washing is difficult, expensive, and can damage the surface of the pool. Here we give you a step-by-step guide on how to acid wash your pool without draining.
Steps
day(s)
Turn off the pump and bypass the timer to prevent the pump from turning on.
Use petroleum jelly to cover any metal fixtures (such as pool rails and pool light rims) in the pool. This will prevent them from becoming oxidized (discolored).
Add 2lbs of No Drān® Acid Wash per 5,000 gallons of pool water.
Add approximately 1 gallon of Muriatic Acid for every 1,600 gallons of pool water. The Alkalinity must reach zero (0).
Brush the entire surface of the pool.
The next day, test your Total Alkalinity and add acid as necessary to keep the Total Alkalinity at zero (0). For every 10ppm of Total Alkalinity add 1 gallon of Muriatic Acid per 15,000 gallons of pool water.
Repeat steps 5 and 6 daily during treatment. Start the day by testing and adding necessary acid to the pool. Then brush the entire surface.
Once the stains are gone OR on the seventh (7th) day of treatment, begin to rebalance the pool slowly. Use a base demand test to estimate the amount of pH increaser you’ll need. Once the pH reaches 7.2 you may turn your pump system back on.
Do not use soda ash, as this will cause stains and scale to reform.
Dissolve your pH raiser in a bucket of water and pour slowly around the pool. For every one (1) pound of your pH raiser, make sure to brush the pool.
Acid washing is typically reserved for aggressive cosmetic restoration. It is the go-to solution when your plaster has accumulated heavy mineral deposits, widespread metal staining, or organic discoloration that regular maintenance and shock treatments cannot remove. Think of it as a “reset button” for your pool’s surface.
Historically, a traditional acid wash required completely draining the pool to scrub the surface with harsh acid—a process that wastes thousands of gallons of water and risks structural damage to your plaster or pool shell.
A No Drān® acid wash achieves similar results by adding specific stain-fighting agents directly to the water. This method uses your pool’s body of water to lift stains safely, evenly, and effectively—eliminating the dangers and costs associated with draining your pool. The result is a smoother, more even look for your pool’s surface.
