Pressure washing or power washing is simply the application of high-pressured water at a very high pressure to remove loose dirt, loose paint, grit, dust, dirt, gum, chewing tobacco and even grime from surfaces and non-porous objects like concrete surfaces, vehicles and buildings. Many people hire a pressure washer service or a professional pressure washing company for their home improvement projects. The pressure washer was developed in the late 1920s as a method of cleaning railroad tracks with a high pressure jet of water. Over the years, the pressure washing industry has evolved into a very diverse and specialized industry with new developments being introduced regularly. Today pressure washing is still used as an effective home maintenance technique, however there are many other ways of cleaning that are less harmful and more economic.
