If you’ve looked at your patio or driveway lately and thought, “Yikes…those pavers used to look way better,” you’re not alone. Florida weather is rough on anything outside, especially porous surfaces like brick, concrete, or natural stone pavers. But before you grab a pressure washer and go full blast, read this first, because cleaning pavers the wrong way can do more harm than good.

Step 1: Understand What You’re Working With

Pavers can be made of different materials, concrete, brick, travertine, and more. Each one reacts differently to water pressure and cleaning chemicals. Most of the pavers we see here in the Treasure Coast are concrete or clay brick, and both are tough but not indestructible.

Big mistake homeowners make: blasting pavers with high-pressure water without knowing if they’ve ever been sealed. That can erode the surface, dislodge sand, and lead to bigger issues like shifting or cracking.

Step 2: Start With a Basic Rinse (No Pressure Yet)

Before you go all Hulk mode with your hose, take a gentler approach.

Here’s what to do:

  • Use a garden hose with a spray nozzle to rinse off loose dirt, leaves, and debris.
  • Check for trouble spots like grease stains, mold, algae, or paint. These will need special attention.
  • Avoid degreasers or harsh chemicals from the big box stores, many of them are not paver-safe and could cause discoloration.

Pro Tip: If you notice white chalky residue, that’s efflorescence, and it needs a specific cleaner. Don’t just scrub it with soap and water.

Step 3: Use a Paver-Safe Cleaner

You’ve got options here, but make sure whatever you use is safe for the specific type of paver and won’t damage the surrounding landscaping.

Your best bets:

  • Eco-friendly paver cleaner (look for “biodegradable” on the label)
  • White vinegar & water mix for basic dirt (not for sealed pavers!)
  • Oxygenated bleach (NEVER use chlorine bleach)

Let it sit for 10 to 15 minutes before scrubbing with a soft bristle broom. Avoid metal brushes, they can leave marks and ruin finishes.

Even with the right cleaner, proper preparation before sealing is essential for long-term results. Learn why in Do I Need to Pressure Wash Before Sealing Pavers?.

Step 4: Be Careful With Pressure Washing

Yes, pressure washing is satisfying, but unless you’re trained (or just plain lucky), it’s easy to etch or scar your pavers, especially around edges and seams.

If you do it yourself:

  • Use a fan tip nozzle, never a zero-degree nozzle
  • Keep the PSI under 2,000
  • Hold the wand 12+ inches from the surface
  • Avoid aiming directly at joint sand

Heads Up: If your pavers have already been sealed, pressure washing with too much force can strip the sealer off. That's a one-way ticket to uneven color and surface damage. When in doubt, leave it to a professional pressure washing crew.

Many homeowners don't realize that even when pressure washing is done correctly, it can still damage pavers if the wrong nozzle, pressure setting, or technique is used. Before tackling the job yourself, read our guide on Can Pressure Washing Damage Your Pavers? to learn what to avoid.

Step 5: Check the Joints

After cleaning, take a look at the sand between the joints. If it looks washed out or patchy, you may need to reapply joint sand. Without it, your pavers can shift, become uneven, or allow weeds to grow through.

This is the part most homeowners skip, but it’s important for stability and longevity.

If your pavers are several years old, this is also a good time to determine whether the existing sealer is still protecting the surface. Our article on How Long Does Paver Sealer Last in Florida? explains what to look for and when it's time to reseal.

Step 6: Rinse Everything Off & Let It Dry

Once everything’s clean and scrubbed, give the whole area a good rinse and let it dry completely. This could take a few hours or a full day, depending on humidity. Avoid walking or driving on it while it dries.

Optional (But Recommended): Seal It

If your pavers have never been sealed, or if the old sealer has worn off, now is the perfect time to seal your pavers:

  • Enhances color
  • Prevents weed growth
  • Helps repel stains
  • Protects against algae and mold

And here’s the kicker: sealed pavers are way easier to clean next time. Not sure whether your existing sealer is still protecting your pavers? Read 5 Signs Your Pavers Need to Be Resealed to learn the warning signs before damage becomes more expensive to fix.

Common Mistakes to Avoid

  • Using chlorine bleach (bad for pavers and plants)
  • Blasting with high PSI before pre-soaking
  • Using metal bristle brushes
  • Ignoring re-sanding and sealing after cleaning

When to Call in the Professionals

Let’s be real, sometimes, DIY just doesn’t cut it. If your pavers are:

  • Covered in mold or oil
  • Heavily stained or sun-faded
  • Poolside (slippery danger zone!)
  • Unlevel, sinking, or cracking
