Soft washing is the process of using the correct cleaning chemicals to kill organic matter like Gloesocapsa Magma algae (the black streaks on roofs), moss, mold, and lichen from roofs, siding, and other exterior surfaces, then rinsing with low pressure, typically 500 psi or less. 

The key is to get the correct soft washing mix on the surface so it can do the cleaning, not the water pressure. Getting that solution on the surface can be done a variety of ways depending on your equipment, budget, and how often and how much you plan to clean.

Let's take a look:

Soft Washing Sprayers

When soft washing first became popular, chemicals were usually applied using a small 12-volt pump-up sprayer. These very basic sprayers were not designed to handle corrosive chemicals such as bleach, so they wore out quickly. They also could not shoot very far. Mixes typically had to be made much stronger than what is common today because they put out such low volumes.

X-Jet M5 Nozzle

Yes, you can use a pressure washer for soft washing by adding the X-Jet M5 Nozzle. The  X-Jet lets you shoot your chemical mix up to 30 feet in the air safely from the ground. The M5 variable nozzle also lets you change the nozzle pattern with the simple twist of a wrist. Go from a zero degree to shoot chemicals on the roof, then immediately water surrounding plants with water only by twisting to a 60 degree fan pattern. 

While the X-Jet is a good way to start if you already own a pressure washer, we really recommend getting a separate soft washing system if you are going to be doing big jobs or frequent projects.
