High-pressure washing is a popular method to clean Florida pools, removing algae, dirt, and calcium buildup. However, improper use can erode pool surfaces, damage finishes, and shorten the lifespan of your pool. Homeowners in Port Charlotte, Punta Gorda, North Port, Rotonda, and Charlotte County should follow best practices to protect their pool while achieving a sparkling clean finish.

Punta Gorda pool

1. Know Your Pool Surface Type

Different surfaces tolerate pressure differently:

  • Vinyl: Very delicate; high-pressure washing can tear or puncture the liner.
  • Fiberglass: Moderate pressure only; strong jets can cause discoloration or surface dulling.
  • Plaster, Gunite, or Concrete: Can handle higher pressures but are still prone to etching if misused.
  • PebbleTec or Aggregate Finishes: Sensitive to high-pressure water; avoid concentrated jets in one spot.

Pro Tip: Identify your pool’s surface before washing — this is the most important step to prevent erosion.


2. Adjust Pressure Settings Appropriately

  • Use 1,200–2,000 PSI for plaster and concrete.
  • 500–1,000 PSI for fiberglass or vinyl.
  • Start on the lowest setting and increase gradually as needed.

Avoid “full blast” settings; concentrated pressure in one area can create divots or pits in plaster and chip aggregate finishes.


3. Use the Correct Nozzle and Distance

  • Fan nozzles disperse water evenly and reduce erosion risk.
  • Keep the wand at least 12–18 inches from the surface.
  • Move the spray in slow, even strokes, never holding it in one spot.

4. Pre-Clean With Brushes or Mild Detergents

  • Remove loose debris manually before pressure washing.
  • Apply a mild pool-safe cleaner to reduce the need for prolonged high-pressure application.
  • Brushing walls and steps helps remove stubborn algae without over-relying on water pressure.

5. Avoid Frequent High-Pressure Washing

  • Overuse can slowly wear finishes over months or years.
  • Implement a routine of brushing, skimming, and chemical treatment to minimize the need for aggressive washing.
  • Schedule high-pressure cleaning once or twice a year for heavy stains or calcium deposits.

6. Protect Pool Equipment and Surroundings

  • Cover skimmers, lights, and jets before washing.
  • Avoid spraying directly on pool plumbing or electrical components.
  • Be mindful of nearby decking or landscaping that may erode under high-pressure streams.

7. Consider Professional Assistance

  • Professionals from Florida Detail use low-pressure techniques and specialized brushes to clean pools safely.
  • They can also recommend sealants or protective coatings to extend the life of plaster or PebbleTec finishes.
  • Local experts ensure your Port Charlotte, Punta Gorda, or North Port pool is cleaned without costly surface damage.

Final Thoughts

High-pressure washing can restore your pool’s appearance, but it’s essential to adjust pressure, maintain distance, and prepare surfaces properly. Combining mechanical cleaning, chemical treatments, and periodic professional service helps prevent surface erosion while keeping your pool pristine.
