For larger jobs such as regular cleaning of driveways, patios, and decks a medium duty pressure-washer is your best bet. A good rule of thumb for your pressure washer guide is to use the PSI rate to determine which equipment best suits your needs. A medium duty pressure washer will have a PSI rating of 2,000 to 3,000 PSI. By combining them with the correct angle power washer spray nozzles, you can effectively clean any surface. The smaller the spray pattern, the more power you can get out of your pressure washer. For example, spray patterns between 0 to 20 degrees can strip paint, cut weeds and roots, and remove stains from wood. Proper care when using this equipment is essential since these nozzles can cut through your skin like a hot knife through butter. For gentler cleaning applications you can use a spray pattern of 30 to 40 degrees. These angles will effectively clean the surface without causing permanent damage.
For the big jobs you’ll need a heavy-duty pressure washer with a psi rate of 3000 to 4500 PSI as well as flow rate of 3 to 4 GPM. As a pressure washer guide, a flow rate of 3 to 4 gallons per minute will allow you to clean large areas in a shorter period of time. Larger flow rates and higher PSI ratings combined with a low angled spray pattern will allow you to use the pressure washer as a cutting tool. The higher the flow rate means more water will be fed through your pressure washer system. It’s important to make sure outdoor hose bib can supply enough water to support a pressure washer with a flow rate of 3 to 4 GPM. An insufficient amount of water will cause the pump to cavitate, which can cause serious damage.
Using power-washers guidebook facts and specification as a pressure washer guide will allow you to select the correct pressure washer for you application. Remember the three most important factors to consider when selecting the right pressure washer are: PSI rate, flow rate, and spray pattern. Taking all these into consideration will ensure that you won’t select a heavy-duty power washer to clean you outdoor patio furniture. After all, without a pressure washer guide the wrong equipment for the job will often cause more work than before you started.
