When you think about all of the things, such as dirt, dust and other soils, flying around in the wind, you wonder where it all goes. It, because of the rain and moisture, will get deposited on the fronts and sides of your commercial building and house. It will also get plastered onto the sidewalk, occasionally added to by the oils and other debris from the street. When this accumulates to the point that it really is a mess, hiring a firm to come in and do the pressure washing you have heard about is the best idea.

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.

The pressure, used in the proper amount and with an appropriate nozzle makes chemicals unnecessary in most applications. The nozzles are a major part of the process and must be chosen carefully. One of the most popular ones oscillates and surges a stream of water composed of many separate streams to power off stuck on material fairly quickly.

There are other nozzles that can delicately sweep a sidewalk or roof. These are various angles of attack that range from a steady stream through an arc of about 180 degrees. This is similar to a coarse push broom and can be used on items such as statuary, that can be damaged by anything stronger.

Based on the nature of the material to be removed and the surface on which it is stuck, the nozzle is one of the most important elements of the system. After the selection of the proper pressure, the nozzle will either be too weak or too strong. The experts who will handle your job will make the correct decision because there is more than the surface to be concerned with.

These cleaning crews do not have to confine their processes to the outside. The many food or chemical plants, across the country, as well as in Holly Springs NC, will benefit from a cleaning that can accomplish this without chemical reactions. Cleaning the ceilings and walls, as must be done from time time, without cross contamination, is achieved quickly with less trouble and in a sanitary way.

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.
