Is your driveway looking tired and worn? With a 3000 PSI pressure washer, the right nozzle, and plain water (or with detergent for extra cleaning), you can pressure wash a driveway back to life.
This guide walks you through prepping, washing, and finishing your driveway cleaning perfectly — and includes helpful tips from my colleague’s father, Frank, who DIY pressure washes his driveway and knows exactly what works.
| Difficulty: Easy to intermediate Estimated time to complete: 20-30 minutes per section (a standard driveway can take about 1-2 hours total) Drying time: At least 48 hours (especially before applying sealant or any paint) Project cost: $20-$100+ (depending on equipment rental and supplies) |
Supplies Needed
Before you start pressure washing your driveway, gather the right tools and materials to make the job easier and safer.
Tools and Equipment
- Pressure washer (at least 3000 PSI for concrete driveways)
- Garden hose (to connect to the washer)
- Spray wand and nozzle attachments (soap nozzle and 25-degree nozzle)
- Siphon tube (for detergent application)
- Pressure washer detergent (specifically designed for driveways)
- Degreaser (for oil stains)
- Stiff brush (to work in tough stains)
- Leaf blower or broom (to clear debris)
- Waterproof sealer (optional but recommended)
- Paint roller and extender pole (for applying sealant)
- Plastic sheeting or tarps (to protect nearby surfaces)
Safety Gear
- Safety goggles (to protect against flying debris)
- Closed-toe shoes (preferably waterproof)
- Gloves (to handle chemicals safely)
- Face mask (if using strong cleaning agents)
- Ear protection (as Frank swears by when using his high-PSI gas pressure washer)
How to Prep Your Driveway for Pressure Washing
A little prep work goes a long way in making pressure washing more effective and less messy. Here’s what to do before you start:
- Clear the area. Move cars, bikes, potted plants, and outdoor furniture out of the way. If your driveway leads to a garage, close the garage door to prevent water from seeping inside.
- Sweep or blow away loose debris. Use a broom or leaf blower to remove leaves, dirt, and small rocks that could get in the way. Pay extra attention to cracks and corners where debris collects.
- Protect nearby surfaces. Cover plants, walls, or doors with plastic sheeting or tarps to shield them from water and detergent. Tape down plastic edges to prevent them from blowing away.
- Apply a degreaser to stains. For oil or grease spots, spray a degreaser and scrub it with a stiff brush to break up tough buildup.
- Check water flow. Identify high and low points of your driveway to ensure water flows away from your home and work area.
Steps to Pressure Wash Your Driveway
Now that your driveway is prepped, it’s time to get cleaning. Follow these simple steps for the best results:
Step 1: Set Up Your Pressure Washer
- Attach the spray wand to the pressure washer hose.
- Connect your garden hose to the machine’s water inlet.
- Select the right nozzle:
- Soap nozzle (black, low pressure): For applying detergent.
- 25-degree nozzle (green, medium pressure): Ideal for concrete cleaning.
- If using detergent, insert the siphon tube into the detergent container. This tube will draw out detergent and mix it with the water stream of your spray wand. However, for routine cleaning, Frank sometimes sticks to plain water, which he finds effective on concrete surfaces.
Tip from Frank: Always ensure water is flowing before you start the machine to avoid burning the pump, especially important with gas models.
Step 2: Apply Detergent (Optional)
Skip if you’re not using detergent.
- Point the spray wand at the surface while maintaining a consistent distance of 8 to 18 inches from the surface, and press the trigger.
- Spray detergent evenly across the surface, starting at the highest point of the driveway. Sweep it back and forth steadily across the entire surface. Overlap your strokes by several inches.
- Let it sit for 5 to 15 minutes to break down grime, but don’t let it dry.
Step 3: Pressure Wash the Driveway
- Switch to the 25-degree nozzle for washing without detergent or rinsing.
- Start at the top of the driveway and move in smooth, overlapping strokes.
- For stubborn stains, hold the nozzle 3 to 4 inches from the surface and go over the area slowly.
- Rinse thoroughly, ensuring no detergent residue is left behind.
Tip from Frank: Using a too-focused nozzle can crack or pit the concrete, so always use the right spray pattern.
Steps to Take After You Pressure Wash Your Driveway
Maintaining your clean driveway is just as important as the washing itself. Take these extra steps to keep it looking great:
Let It Dry Completely
Allow at least 24 to 48 hours for the driveway to dry before applying sealant or parking vehicles. Check for any remaining wet spots and use a squeegee if needed to speed up the process.
Apply a Waterproof Sealer (Optional but Recommended)
Sealing your driveway helps prevent future stains and prolongs its life.
- Pour the sealer into a paint pan.
- Use a roller with an extension pole to apply an even coat.
- Let it cure for 24 hours before you park or walk on the surface.
Routine Maintenance
Sweep regularly and hose down your driveway occasionally to prevent buildup and extend the time between washes. You can also spot-treat stains immediately with degreaser and a stiff brush.
Tip: Aim to pressure wash once a year to keep your driveway looking its best.
Safety Tips from Experience
Frank, a veteran user of a gas pressure washer for their concrete driveway, shares these safety pointers:
- Never point the sprayer at yourself or others. A focused stream of water is dangerous.
- Avoid using the machine while on a ladder. The kickback can throw you off balance, especially with high-PSI gas engines.
- Never run the machine without first connecting and turning on the water. This prevents pump damage.
- Don’t refill the gas while the machine is hot.
- Be cautious around the muffler. It gets hot during operation; ensure the hose doesn’t contact it.
- Always wear ear and eye protection, gloves, and sturdy shoes.
FAQ
For concrete driveways, use a pressure washer with at least 3000 PSI and a flow rate of 4 GPM (gallons per minute). For brick or softer surfaces, lower the PSI to avoid damage.
The best time to pressure wash is during mild, dry weather, typically in spring or fall. Avoid extreme heat, as the water can evaporate too quickly, and freezing temperatures, which can cause water to expand in cracks.
Yes. Sealing your driveway protects it from stains, cracks, and wear. Apply a waterproof sealer after the driveway is completely dry, usually 24 to 48 hours after washing.
The average costs around $215, with the range usually from $150 to $305, depending on the driveway size and grime level. DIY pressure washing may be cheaper, but it requires renting or owning equipment.
