The Science Of Pressure Washing Means No Chemicals

By Stella Gay


The world is a fairly dirty place. Your commercial building will get dirty just because the wind blows debris around. The rain will mix with this dust, other soils and even allergens to create a mass that can stick on anything. The front of your house, your building and the sidewalks. It will cloud the glass in your windows and make a mess in the entry way of your office building. The best way to get all of this cleaned up is to hire a company that does the pressure washing you may have heard about.

This cleaning process, often called pressure cleaning or even power washing uses high pressure water to scrub all surfaces clean of debris, contamination and, usually, oily, sticky material that does not respond to brushes and a bucket. The professionals, who do this every day, are trained in this specialized cleaning method and use the correct equipment to accomplish this.

The pressure that is being discussed is in the commercial range of between 250 PSI to 6500 PSI. The higher the number, the greater the pressure as PSI means pounds per square inch. The mechanical action of the water will agitate the surface and remove even some very dried on material. No chemicals also means no chemical reactions with anything being cleaned.

No chemicals are needed, in most cases, because of the mechanical action of this pressurized water. The raw force is accentuated by the nozzles that can be attached to the end of the wand. There are many different configurations of these. The most popular, for large areas, such as a parking lot with a lot of grime, is the power head. This oscillates, providing a continuous pressure that agitates the surface and removes grime quickly.

Other nozzles, available, will help sweep roofs and walkways because of their delicate nature. These range from a steady stream to a fan that can be formed through an entire 180 degree of arc. These are helpful when the work involves careful cleaning of roofs, statuary or other things that can be damaged by a more powerful burst.

When selecting this very important part of the cleaning system, the crew will make the decision based not only on the surface to be cleaned and the nature of the contamination, but also on the surrounding elements. This means the presence of cars, pets or plantings that may be affected. Cleaning in a green way means looking at everything that can be impacted.

It is interesting to note that a professional crew, trained and experienced in cleaning this way, do not have to be confined to the outside. This type of chemical free cleaning has been used, to great effect, inside of food processing plants as well as chemical manufacturing lines. Since the best sanitizer is still plenty of fresh, cold water, this is a perfect system to use for these areas. Cross contamination is not a problem with this type of cleaning.

Holly Springs NC has many high technology firms and businesses. They appreciate and depend on science in manufacturing products that are used throughout the world. The cleaning that can be accomplished uses science to provide it. This will help continue to give NC a step up in products produced, science in general and sanitary conditions second to none.
