Top 10 Pressure Washing Tips for Cleaning Your Concrete Driveway

Materials Needed:

  • broom

  • stiff brush

  • pressure washer

  • pressure-washer detergent

  • spray degreaser

  • safety gloves

  • goggles

  • plastic sheeting

  • painter’s tape

  • 20-meter hose pipe

  • paint tray

  • waterproof driveway sealer

  • paint roller cover

  • paint roller handle

 

Step 1: Protect exterior walls and door

Use the plastic sheeting to cover any nearby walls and doors and tape in place with the painter’s tape. Pressure-washing uses a lot of force – protecting your walls and doors keeps them safe from flying debris or accidental damage caused by the pressure washer.

Step 2: Sweep your driveway

Use a broom to sweep away any surface dirt, dust and other particles.

Step 3: Take the proper precautions

Before using a pressure washer or cleaning products, carefully read the instruction manual and/or safety guide. Every model is different and may require different preparation, tools, attachments or special detergents.

Step 4: Degrease the surface

Prep the surface of your driveway for cleaning by first applying a driveway degreaser. This will make it easier for the pressure washer to wash away tough stains. Spray the degreaser onto the surface and let sit for a few minutes. Then scrub the stain with a stiff brush to loosen it.

Step 5: Attach the spray wand tip

The instruction manual will tell you which tip is to be used for washing (it’s frequently labeled “soap”). Find this tip and attach to the head of the spray wand.

Step 6: Attach the hoses

Attach the supplied pressure washer hose and wand to the pressure washer. Then run your 20-meter hose pipe from your water supply to the pressure washer where indicated. Turn on the water.

Step 7: Prepare your pressure washer for cleaning

If your pressure washer came with a detergent siphon tube, place the free end directly into the container of detergent. After the pressure washer is running, the detergent will automatically get sucked into the spray wand.

Step 8: Spray detergent

Put on your safety gloves and goggles, then turn on your pressure washer and begin to apply the detergent by holding down the spray handle. Try to maintain the specified distance (usually 8-18 inches) between the sprayer and the concrete. Using a smooth, back and forth motion, spray the detergent onto the concrete, slightly overlapping each stroke so that there aren’t any gaps or missed places. Once finished, allow the detergent to sit for about five minutes, or as long as the detergent’s label recommends.

 

Step 9: Pressure-wash your concrete driveway

Remove the detergent (“soap”) tip and snap the spray tip (usually labelled “25 degree”) onto the wand. Pressure wash your concrete driveway using the same method as above, with slow, smooth, back and forth motions and allowing each stroke to slightly overlap. Ensure that all of the detergent is washed away.

 

For especially tough stains, hold the spray wand closer to the surface, holding the spray wand in place until the stain is fully removed.

Step 10: Seal your concrete driveway

Once your driveway is fully clean, pour the waterproof driveway sealer into the paint pan and use the paint roller and cover to apply the sealer to the driveway. Begin in the middle and slowly work your way out to the edges, ensuring that the entire surface is covered. Do not park on the driveway for at least 24 hours.
