WASHING A REAL DIRTY HOUSE

Here's a good example of using a pressure washer on your house to clean your siding. When people hear 3000 psi they think it will blow the siding off the house which I can understand when hearing that. But it's only at three to four inches from the spray tip were the 3000 psi  is, as you move further away the pressure decreases, acting more as a water sprayer than as a "pressure washer". Using the pressure is more used for cleaning maybe some tough spots,sidewalks, stone or cement walls. But for the do it yourselfer's it show you  the proper movement to use when using the spray-gun. No matter how tall the house always start at top working to bottom when rinsing.
