Powerwash Exterior Surfaces? – from HomeAdvisor Newsletter

Power washing can be done on almost any surface and is a great way to keep things like your driveway, parking areas, decks and even your home exterior looking clean and new.  Before you power wash, there are some things you should think about first.
What is the difference between power washing and pressure washing?

When you talk to your professional, make sure that you understand the difference between the two terms.  Many use them interchangeably and you may end up not getting the service you anticipated.

Power washing makes use of a steady and somewhat powerful stream of hot water. The temperature of the water is the key. By setting the temperature gauge to a specific setting, it is possible to dislodge items such as chewing gum from sidewalks and decks with ease. At the same time, the stream of hot water also comes in handy in killing moss and weeds, and ridding the surface of any mold or mildew that has built up. If there is a lot of gunk and other matter to cut through, a power wash is the way to go.
By contrast, pressure washing relies on the force of the water stream rather than the temperature. A pressure wash works very well for cleaning surface dirt from walkways, walls, patios and decks. Pressure washing masonry cleaning is especially common, as the technique does an excellent job with any type of concrete, brick, or cinder block construction. When there is no ground-in dirt or mold to contend with, pressure washing provides a quick and easy cleaning solution.
What are dangers of power washing?

Because the water used for power washing is powerful AND hot, it can be easy to ruin surfaces or get injured.  Only trained professionals should attend to your power wash needs because they will know what can or can’t be cleaned using this method.  Talk to your professional about the possibility of damage and what they will do in that event.

What are the best things to be power washed

Driveways:  Power washing is ideal for restoring driveways and parking areas whether they are concrete, brick, or asphalt.

Decks, patios, and wood: Any wood surface will look brand new after power washing. This includes fencing, decks, patios, gazebos, and any outdoor structure made with wood.
Garages, gas stations, and trailers: Power washing works on a variety of surfaces and is not just limited to outdoor structures and buildings.
Vinyl siding:  On a lower heat setting, your vinyl siding can benefit from a power wash.
Does power washing use chemicals?

Some power wash professionals do use chemicals.  Be sure to ask what is being used and any implications of those chemicals.  If it’s important to you, ask if your contractor can use non-toxic and biodegradable materials and whether or not they provide water reclamation services when needed to prevent run-off into public water systems
