How to Clean Pavers in Florida (Mold, Stains & Weeds)

Maintenance · 5 min read · MJC Pavers

To clean pavers in Florida: sweep, then wash with water and a mild paver-safe cleaner (or diluted simple green) using a pressure washer on a wide, low-pressure tip. Treat mold/mildew with a paver-safe algae cleaner, pull or spot-treat weeds in the joints, then re-sand and reseal to keep them from coming back.

Step by step

  1. Sweep and clear debris and furniture.
  2. Pre-treat mold/mildew (common in humid SWFL) with a paver-safe algae/mildew cleaner; let it dwell.
  3. Wash with a pressure washer using a wide 25°–40° tip held back from the surface — too close or too narrow blasts out the joint sand.
  4. Handle weeds in the joints — pull them or spot-treat, then plan to re-sand.
  5. Re-sand the joints with polymeric sand once dry.
  6. Reseal to lock everything in and slow future mold, stains and fading.

What to avoid

  • High-pressure, narrow tips — they strip joint sand and etch the surface.
  • Harsh acids or bleach — can discolor pavers; use paver-safe products.
  • Sealing over dirt — traps grime; always clean first.

The real fix for weeds and mold: seal it

Weeds and mold in Florida keep coming back when the joints are open. Re-sanding with polymeric sand and sealing is what actually keeps them out long-term — see how often to seal pavers in Florida and our sealing cost guide.

Frequently asked questions

How do I get mold off my pavers in Florida?
Use a paver-safe algae/mildew cleaner, let it dwell, then rinse or pressure wash with a wide low-pressure tip. Re-sanding and sealing afterward keeps mold from returning quickly.
Can I pressure wash pavers?
Yes, carefully — use a wide 25°–40° tip held back from the surface. Narrow, high-pressure tips blast out the joint sand and can damage the pavers.
How do I stop weeds growing between pavers?
Pull or spot-treat them, then re-sand the joints with polymeric sand and seal. Open joints are what let weeds and ants back in.
