Get matched with top pressure washers in Altadena, CA

Some hard surfaces, such as concrete and asphalt, tolerate pressure washing well, and it can be a great way to keep them clean. However, you should avoid pressure washing clay or grass as you'll quickly destroy them.

Additionally, pressure washing can remove paint lines from any surface, so you need to be careful, and it may be best to let professionals handle the job.

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.

This process doesn’t necessarily require soap or detergent, but it definitely helps. You can get by with just using water, but remember, brick requires a lower-than-average pressure level when compared to concrete, so forgoing detergent increases the time it takes to spot clean stains and debris once you finish with the pressure washer. Brick is especially porous, so the less water you use on it, the better.

Whether you need to winterize your pressure washer depends on where you store it. If you can keep it in a relatively warm place with no risk of freezing, you won't need to add antifreeze. However, if the machine will be stored in freezing temperatures, any liquid left in the water pump can freeze, expand, and cause severe damage. To prevent this, add antifreeze to keep it in good condition. While some suggest emptying the machine with compressed air, this can be a tedious process that may not fully drain the liquid. Regardless of storage conditions, it is also good practice to empty the gas chamber and refresh the oil before winter storage.
