The right way to clean a Florida driveway is to pre-treat the surface for algae and oil, then clean it with a flat surface cleaner at the correct pressure for the material, and finish with a post-treatment that slows regrowth. Concrete tolerates more pressure than pavers, and using the right tool matters far more than sheer power.
Why a surface cleaner, not just a wand?
A pressure washer wand alone leaves stripes, zebra marks, and uneven cleaning that becomes obvious once the driveway dries. A flat surface cleaner spins two nozzles under a shroud, cleaning a wide, even path at consistent pressure. It is the single biggest difference between an amateur result and a professional one, and it also cleans faster with less water waste and less splatter on your garage door and walls.
Pre-treat first
In Florida, most driveway grime is organic. Rinsing alone will not kill algae and mildew, so the correct method starts with a cleaning solution:
- Apply an algaecidal detergent across the slab and let it dwell.
- Hit oil and grease spots with a dedicated degreaser.
- Treat rust stains with a rust remover, never just pressure.
- Re-apply to stubborn shaded areas where growth is heaviest.
Pre-treatment does the real work; pressure just rinses the result. Skipping this step is why blasted driveways green up again within weeks, since the roots survive an untreated rinse.
Correct pressure for each surface
Concrete
Broom-finished concrete handles a surface cleaner well. The goal is even, thorough cleaning, not maximum PSI. Too much concentrated pressure from a turbo nozzle can etch lines into the slab that never come out, so the surface cleaner spreads the force safely across a wide path. Consistent overlapping passes prevent the striping that ruins a DIY job.
Pavers
Pavers are more delicate. Excess pressure blasts the joint sand out, chips edges, and can dislodge stones. Pavers are cleaned at lower pressure with the surface cleaner, and the joints are re-sanded afterward. Many homeowners then seal the pavers to lock everything in. Our paver cleaning service covers cleaning, re-sanding, and sealing.
The step-by-step method
- Clear the driveway and pre-wet nearby plants and beds.
- Apply the algaecidal solution and spot-treat oil and rust; let it dwell.
- Clean in overlapping passes with a flat surface cleaner.
- Detail the edges and corners the surface cleaner cannot reach with a wand.
- Rinse the whole slab toward the street, keeping runoff off the beds.
- Re-sand paver joints and apply a post-treatment or sealer as needed.
Florida-specific tips
Our salt air and humidity mean regrowth is quick, so a post-treatment that discourages algae extends the clean look. Clean on a day without a downpour on the way so solutions have time to dwell. Protect your landscaping: pre-soak beds and rinse them after, because our lush plantings do not appreciate concentrated runoff. And avoid the hottest part of the day, when solutions dry before they can work.
Should you DIY or hire out?
A small, lightly soiled concrete driveway can be a reasonable DIY project if you rent a surface cleaner and use the right chemistry. But pavers, heavy oil, rust, and large or shaded driveways are where pros save you from permanent mistakes and re-sanding headaches. You can compare options on our driveway cleaning page, and if the front of the house also looks tired, a house soft wash at the same time makes the whole property pop.
Finishing touches that make the difference
The details separate a driveway that looks professionally cleaned from one that looks merely rinsed. Edging along the grass line and cleaning right up to the garage threshold prevents the dirty border that gives away a rushed job. Cleaning the apron where the driveway meets the street ties the whole surface together, since that section collects the most road grime. On decorative or stamped concrete, a fresh coat of sealer after cleaning revives the color and pattern. And a light post-treatment across the slab leaves an invisible barrier that slows the return of algae, so the driveway stays cleaner through the next rainy season instead of greening up within weeks.
