The History of Pressure Washing

 

Pressure washing has been around since the late 1960’s, with less powerful washers than today’s safe and efficient models, but with lower cost and greater convenience than what had been possible up until that point.Get More Information power washing raleigh.

Different Types of Power Washers
Generally, there are seven different types of power washers:

Electric
Diesel
Gasoline
(Natural) Gas
Ultra High Pressure
Hydraulic High Pressure
High Pressure Steam Cleaner
Non-electric pressure washers can deliver a lot of pressure (twice that of electric) while also being more portable and sometimes capable of generating hot water to further work on stubborn stains, debris, oil and grease removal. But their drawback is their exhaust and noise, making them dangerous for indoor use. Electric, on the other hand, are perfect for indoor use, requiring a normal electrical outlet, but lacking in power (only about 1,000 PSI of water pressure).

Worried you might not be using the right water pressure? Err on the side of lower pressure. You can always switch to a nozzle with a smaller angle, stand closer for more power, or use a pressure washer with more power, but using too much pressure or standing too close can damage the surface you’re trying to clean, and increase the chances of debris hitting you at high speed.

Different Stains
For graffiti removal, medium water pressure is normally used with chemicals, sand, air and/or hot water. Great care must be taken not to damage the surface being cleaned due to excessive surface removal. Professionals excel at using the right tools and chemicals, etc.

How to Use a Pressure Washer
Make sure you have plenty of water going to your pressure washer, since too little water can starve and damage a power washer, since a pressure washer pump doesn’t draw more water from your home’s water pipe to the washer that it is connected to.

Make sure you use the following when using a pressure washer:
Rubber gloves
Eye protection (goggles)
Work shoes
Reliable water Source
Long water hose
Commercial grade power washer with accessories
Scrub brush
Cleaner
Power source (electric or gasoline)
Pressure washer accessories
Power washer chemicals, sand, etc. (as needed), that are designed to work with your particular pressure washer
Pressure Washing Your Home

Power washing is done with a mechanical sprayer that uses a nozzle to increase water pressure and decrease the water volume used, so as to remove dirt, grease, mold, grime, dust, mud, dirt and other contaminants from home’s external surfaces, as well as buildings, vehicles, road surfaces, driveways, decks, and other hard surfaces that need occasional cleaning. Equipment can be rented or bought, or used by power wash professionals. Pressure as high as 30,000 pounds per square inch or higher can be attained to remove really stubborn stains.

Different Types of Power Washer Accessories
Most pressure washers have an attachment that attaches directly to the trigger gun, and which allows the water to flow in a pencil thin jet of water, while others can cause the water jet to be ejected in a triangular plane. Other attachments can be used for particular applications as well. Professionals are well accustomed to the varying combinations of nozzles and detergent attachments, and whether the detergent will be introduced before (low pressure, downstream injector) or after (high pressure, upstream injector) the pressure cleaner water pump. Be careful! Professionals know which chemicals will damage a water pump and therefore which ones will need to be introduced after the pump (the latter, high pressure, upstream injector mentioned above). If you do it yourself, make sure you carefully research your detergent type before starting your power washing.
