How to Use a Power Washer

Power Washer is an equipment used to clean outdoors items. Its applications can be manifold with the most prominent being the cleaning of garbage cans, cooking grills, lawn mowers, automobiles, and stripping of paint. One interesting fact about the usage of power washer is its ability to save a lot of water. A common power washer can save upto 80 percent water as compared to a garden hose.

The equipment basically consists of a water hose, connected with a specially designed nozzle which receives water under pressure. This pressure is provided by an electrical motor and varies according to requirement. In general, for home based usage, pressure around 3000 psi is enough.

Power washers are classified on the basis of pressure and the flow rate. While pressure is specified in pounds per square inch (psi), the flow rate is rated in terms of gallons per minute and determines the rinsing level on the object to be cleaned. There is also a classification in terms of hot and cold water. Washers that use cold water are less expensive, but are naturally less efficient.

While using a power washer, you need to get hold of the some other necessary tools and materials, depending upon the nature of the operation. Detergents and brushes (including wire brushes) are the most commonly used in conjunction, while degreasers and sandpapers can also be used.

The steps involved in the usage of power washer vary with the applications, but we will try to jolt down some of the general ones, which are a must in almost every case.
