Safe Surfaces to Use a Pressure Washer On

A pressure washer does the job of blowing away gunk quickly— and satisfyingly. Nothing compares to the unparalleled strength of these devices to clean paths and remove ancient the paint from a deck.


It's simple to become drunk with power and make a mistake when using this tool, because of its aptitude to seemingly clean anything and everything away.  It is also fairly easy to get injured when using this power tool, but more on that later. 

"You may want to wash all around the house, but that's not always a great idea,”  Dave Trezza, the engineer who oversees consumer reports pressures washer testing, informs us. "The superficial water flow may harm paint, wood,  and even certain kinds of stone." Below is a guide about when it's useful to wash with a pressure washer, and when a gentler method is the correct way to go about cleaning your house. 


The Deck


Yes! This can be pressure washed. Decks made from hardwoods like Ipe, Camaru, and Tigerwood will take the power just fine. Decks of wood that are made of treated wood are usually okay too, provided the nozzle is not kept too close when spraying. However, it is not necessary to clean all the decks with a washer. Newer composite decks from brands like TimberTech and Trex are often resistant to deep staining, and can be cleaned easily by hand. If a light scrub is not enough to clean up your composite deck, then rinse it with a garden hose, and check the guarantee terms before a pressure washer is used, to ensure you do not void your contract. 


The Roof


No, you should not pressure wash the roof! As tempting as it is to blast unsightly moos and algae away, is dangerous, not to mention damaging, to clean your roof with a pressure washer. For a start, while you're sitting on a ladder, we never recommend using a pressure washer because the blowback can throw you off the latter. The mighty stream of water can also break the shingles on the roof, and strip them of the embedded granules, which help extend the life of the roof with asphalt shingles.


A longer-term strategy to take care of your room would be to trim overhanging branches, or reduce trees around the house if there is an overwhelming amount of shade, so that sunlight reaches the roof. That's the key to avoiding the growth of moss and keeping your roof in good condition! 


The Car


No, you should not use a pressure washer for your car. Many people, of course, use a pressure washer to clean their car, but that can do more harm than good. With a pressure washer, the paint may damage or nick, leading to rust. A garden hose and soapy sponge generally gets the job done just fine. Use a little elbow grease on problems such as wheels, and a specialized cleaner. 

A Concrete Walkway/Driveway


Yes. Concrete can easily withstand a strong cleaning without much concern about etching. A thinner nozzle will be more effective, when it comes to cleaning grease related stanes. Use low pressure, and lather the surface that’s moldy or mildew-covered in foam first. 


The Siding to a House


Occasionally. Vinyl siding is durable and usually can put up with pressure washing without much concern.  The same applies to cement fiber siding. However, aluminum siding can be nicked, so the best thing is to begin with a wide nozzle at the smallest pressure, and only use more pressure in more problematic spots.
