No doubt about it, there are a lot of tough cleaning jobs around the outside of your home. From oil stains on the driveway to prepping your deck for a new coat of stain, a power washer from Norwall Power Systems can take the elbow grease out many difficult and time-consuming outdoor cleaning tasks.

Residential gasoline power washers use a pump to increase average home water pressure of 45 PSI to a dirt-blasting 2000 to 3000 PSI. The volume of water is significantly decreased, but the high-pressure spray can remove dirt, mold, and even oil stains from just about any surface.

Cleaning a Deck

After a year or so, the once bright wood of a deck begins to fade. Good maintenance includes yearly cleaning and reapplication of the wood sealer.

Loosen dirt and grime using the yellow 15-degree nozzle and spray the deck surfaces at a 45 degree angle. Apply a detergent made for decks and wood surfaces using a soap dispensing nozzle, and then give the deck a final rinsing with the white 40-degree nozzle. Let the deck dry thoroughly, usually overnight, and apply the stain the next day.

Washing the Car or Boat

Few tools make washing the car or boat as easy as a power washer. Add a brush accessory and the job becomes easier than ever before.

The white 40-degree nozzle is usually fine for most parts of this job. Rinse the entire surface to remove the surface dirt, then switch to a black soap nozzle or a brush to apply the soap. Give your car or boat a final rinse to wash the soap away and its ready for coat of wax.

Tough areas like insect-splattered bumpers and hub caps coated with road grime and brake dust might need a bit of extra oomph provided by a green 25-degree or yellow 15-degree nozzle to blast away the toughest dirt.

Concrete Floors Walks and Drives

The first time you clean your garage floor with a power washer, you might just declare it the most fun you’ve ever had cleaning anything. And those weeds that perpetually grow between the cracks in your drive or sidewalk-they don’t stand a chance.

Note: Only clean well-cured concrete with a pressure washer and cleaner.

Loosen dirt with the 15-degree nozzle and direct the spray at a 30- to 45-degree angle. Add the detergent next and apply liberally over any oil stains. Be sure to follow the detergent instructions on the bottle and use the soap nozzle to apply. Wash the dirt and oil away with the yellow nozzle. For bad stains, the zero-degree red nozzle might be required. Old stains may need multiple applications of detergent.

Use the red, zero-degree nozzle to dig the dirt out of sidewalk and driveway cracks and take the weeds with them. Fill the cracks with a caulk made for concrete cracks and those weeds will never come back.

Cleaning House Siding

Whether just to clean up the house or prep it for painting, if you’ve ever washed an entire home you know how much work it is. A power washer makes quick work of the job, but doing it right is important.

Never use the red zero-degree nozzle on wood, vinyl, or aluminum as it can damage the siding. Apply detergent with the black nozzle, then wash the siding with a green 25-degree or white 40-degree nozzle. Direct the spray downward at a thirty- to forty-degree angle to prevent pushing water up under the siding.

Caution: Power washers are not for washing windows and may break glass.

Many Uses

Buy a power washer and you’ll put it to use on an endless array of cleaning jobs. They do wonders on BBQ grills, rain gutters, patio furniture, lawn mowers and garden tillers. Trash cans clean up in a breeze and cleaning out the dog kennel won’t get any easier.
