Pressure washers are better for residential use. Power washers are best suited for cleaning very hard surfaces (like concrete and cement) and removing tough stains or tacked-on grime. Meanwhile, pressure washers have more uses. For example, you can use one to deep clean a wooden fence, spray down your vinyl siding, or clear out your gutters.

Professionals use high-pressure steam cleaners, brushes, and specialized cleaning solutions for effective results.

You don't technically need to seal your driveway after pressure washing, but doing so will help keep your driveway clean for longer. The best driveway sealer depends on the type of driveway you have. To seal asphalt, consider an asphalt emulsion sealer, fast-drying sealer, or latex acrylic sealer. Concrete driveways commonly use acrylic sealers or penetrating sealers.

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.
