Yes, it’s pressure washer that can help to solve your problem. But, you don’t know about the device. First, you should know some vital features and how they work. Let’s look at the procedure of how to wash a house effectively.

1. Nozzle

The nozzle is one of the most important features of a pressure washer. It’s also a spray tip. Let me tell you an example, you want to reach the window which is 10 feet far from you. But it’s not possible for you to reach there.

Now, what can you do? Use the nozzle to solve the problem. Always use the 25 or 40-degree nozzle tip for better performance. Controlling the flow and velocity is the main job of the nozzle.

2. Detergent

What do you think? Can the water only remove the dirt from your house siding? No, the detergent makes the cleaning process more comfortable.  Detergent can make your building smooth and shiny. The house siding may risk damaged without using the detergent.

There are different kinds of detergent in the market. Choose solutions that are environmentally friendly.  For more info here’s our guide on the best vinyl siding cleaner.

3. Brush attachment

A brush isn’t essential while pressure washing your house siding. Moreover, you can use the brush attachment for better cleaning capacity. It can also give a better performance of the power pressure. The brush will scrub and push the dirt and grime.

There are different kinds of brush. The brush can clean the dirt off vehicles, decks and other surfaces. They are comfortable to use. Choose a brush of less than $40.

4. Extension Wand of the pressure washer

Owner of a two-storied building or more? The extension wand is suitable for you. It can help your power washing easy. It has extra attachments to put on the end of the extension wand to reach the highest area.

The process is possible to safely stand on the ground. You can remove the dirt of second storied surfaces. It can also clean the gutters from the ground. Telescoping extension wand is our first choice for you.

5. GPM and PSI of a pressure washer

Let me explain about the GPM and PSI. GPM stands for gallons per minute. It means the amount of water flow that comes from the pressure washer. And the PSI stands for pounds per square Inch. It refers to the amount of cleaning pressure that the pressure washer can produce.

You can select the machine with the GPM of 2.3 and PSI of 2600 for better performance. Try to find a higher GPM pressure washer. Because the high GPM can clean the large surface.
