No, you should not use bleach when pressure washing your driveway. Using bleach can corrode the pressure washer's seals and nozzles, causing permanent damage. It also releases harmful chemicals into the air that can harm plants, flowers, and animals nearby. Instead, opt for safer pressure washing cleaning agents specifically made to treat tough stains.

After a professional pressure wash, your driveway will stay impressively clean for months to a full year. Environmental factors such as heavy traffic, nearby construction dust, and high rainfall shorten this period, while low usage and regular upkeep extend it. Consistent maintenance preserves the pristine look and enhances your home’s curb appeal.

You are not required to seal your driveway after pressure washing, but applying a quality sealant greatly extends the clean appearance and defends against stains. For asphalt, use an asphalt emulsion, fast-drying, or latex acrylic sealer; for concrete, choose an acrylic or penetrating sealer. Sealing enhances durability and curb appeal while protecting the surface from environmental wear.

Depending on environmental factors and use, you can plan on pressure washing your driveway twice a year. If your driveway doesn’t have a lot of wear and tear, pressure washing once a year will keep it in good condition. Regular cleaning maintains curb appeal and removes persistent dirt and debris that can dull the surface and lead to deterioration.

It takes between one and four hours to pressure wash a driveway, depending on its size, material, and overall condition. Small driveways finish in one hour, medium-sized ones require two hours, and larger driveways need up to four hours. This estimate doesn't include additional preparation or sealing time, which can extend the total project duration.
