What is power washing?

Power washing, or pressure washing, is the growing application of high pressure water spray. Produced by specially designed pumps, this spray is a hundred times more powerful than the typical garden hose. On concrete it is used to remove unsightly mold, bubble gum, and other dirt stains. Wooden decks are returned to the look of new wood, void of graying and fatigued finishes. And on houses, the appearance of siding (namely aluminum and vinyl) is greatly improved by removing pollution, mildew, and other signs of neglect.

FAQ's

What chemicals can be used? 
Use only cleaning solutions that are power washer approved. Never use bleach as this will damage the pump, hose, and spray wand.

Why can't chemical injection be used under high pressure? 
Applying chemicals in low pressure has two advantages. First, if the chemicals were applied in high pressure, they will splash off, resulting in wasted solution. Secondly, because chemical injection only works in low pressure, you can change from low pressure to high pressure at the wand, instead of going back to the unit to engage chemical injection. 

Can I use bleach in my pressure washer? 
NO! You must NOT use any household bleach with your machine. By using them you will damage the seals and o-rings in the gun, wand, hoses and pumps.

Can I use hot water with my pressure washer? 
NO! Hot water can cause damage to the o-rings and pump. 

Is pounds per square inch (PSI) or gallons per minute (GPM) more important?
Both. The PSI delivers the "punch" to a washing application, or in other words, forces the contaminant off the surface. The GPM will flush the contaminants. Most homeowners and pressure washer contractors will opt for more PSI while the farmer and agriculture needs the flow to push contaminants to the final destination.

When should I drain the gasoline from the engine? 
You should always remove the gasoline from the engine if you plan to store the unit in your basement or transport it in a vehicle. You should never store combustible materials in your home. 

Where is the best place to store my pressure washer?
Store your pressure washer in a clean, dry place that is well ventilated away from open flames or sparks. If you plan to store your pressure washer in a shed or unheated garage, be sure to winterize before the first frost. If you plan to store it in a basement, you should remove all gasoline from the engine.
