Pressure washing or power washing is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, chewing gum and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces.
There's a good scientific reason why water gets things so clean: its molecules have a slight electrical polarity (one end is positively charged and the other is negatively charged), so they tend to stick to things all by themselves. Detergents (soap chemicals) help water to do its job even better by breaking down gunge and grease and making it easier for water to flush away. But some kinds of ground-on dirt just won't budge, no matter how hard you try. That's when a pressure washer comes in really handy. It uses a narrow, high-pressure jet of hot or cold water to blast dirt free. Since water is traveling fast, it hits the dirty surface with high kinetic energy, knocking dirt and dust away like a constant rain of tiny hammer blows. It's only water, though, so it doesn't damage most hard surfaces.
Having said that, it's a good idea to test a pressure washer on an inconspicuous area before you start work to make sure it doesn't harm the surface you're cleaning.

How To Choose The Most Powerful Pressure Washer?
A pressure washer lets you clean a variety of things faster, better and easier. Pressure washers remove built-up mold, mildew, dirt and grime to restore surfaces to like-new condition,
- Gas vs. Electric
Don't just get it wet. Get it clean with a gas-powered pressure washer. Gas pressure washers are more powerful than electric pressure washers so they can get the job done more efficiently.
- Cleaning Power is Key
The cleaning power of a pressure washer is determined by two criteria: the water pressure (PSI) it produces and the water flow (GPM) through the washer. The combination of PSI and GPM determines a pressure washer's cleaning power (CP). CP offers a better indication of a machine's overall performance, and is useful when comparing pressure washers. To calculate CP, multiply a pressure washer's maximum PSI rating by its GPM flow (CP = PSI X GPM).
- PSI (pounds per square inch) refers to how much force a pressure washer is capable of producing to propel the water stream at the cleaning surface. For example, a pump spray bottle has high water force, but low water flow.
- GPM (gallons per minute) identifies the amount of water a pressure washer uses to clear dirt and grime from the cleaning surface. An unrestricted garden hose illustrates the idea of high water flow and low water force.
- Cleaning Systems
Pressure washers equipped with a detergent injection system automatically siphon and mix cleaning detergents into the water stream for even more effective cleaning. For added convenience, some models come with onboard detergent storage tanks.
