The ideal PSI (pounds per square inch) for a pressure washer depends on the surface you are cleaning. For general home use, a pressure washer with a range of 2,000 to 3,000 PSI is recommended and powerful enough for most residential projects.

The specific PSI you should use varies by task:

• High-Pressure Tasks (2,500-3,000 PSI): Tough materials like concrete, stone, masonry, and brick can handle higher pressures. This is suitable for removing stubborn stains from driveways or cleaning graffiti.

• Low-Pressure Tasks (around 600-1,300 PSI): Softer surfaces require a gentler touch to avoid damage. Use a low PSI setting for cleaning wood decks (especially softwoods like pine and cedar), vinyl siding, outdoor furniture, and stucco.

For best results, choose the right nozzle for your surface, such as a 15-degree nozzle for siding or a surface cleaner attachment for driveways. Using an extendable wand can also make the work easier and more ergonomic.

The best cleaning solution for stamped concrete is a combination of water and mild soap. Dish soap and laundry detergent are good options. For more stubborn stains, you can use an alkaline cleaner that removes oil and grease. In either case, you’ll want to steer clear of abrasive cleaners and harsh chemicals which can damage the concrete.

Experts typically recommend pressure washing your driveway at least once per year to keep it looking great while preventing stains, cracks, and unwanted vegetation. However, if your driveway gets a lot of use, you might want to pressure wash it more often to keep it looking like new. 

You should wait until your pavers have completely dried and cured before pressure washing them. Wait at least three to five days, though some sealants may need up to an entire week. Rushing that timeline can mess with the finish, weaken the seal, or leave streaks that are tough to fix. Once the sealant has fully set, stick to a gentle approach. Keep the pressure under 1,500 PSI and hold the nozzle at least two feet from the surface. Anything stronger or closer can blast the joint sand loose or wear down the sealant you just applied.
