Place a cleaning solution like water and soap or vinegar and water in a bucket. Insert the black tip into the pressure washer as it’s designated to spray the cleaning solution first.

Turn on the machine. Spray the cleaning solution evenly across the surface, starting from the bottom. Turn off the pressure washer when finished and replace the black tip with the 40-degree tip. Turn the machine on and begin spraying evenly from the top down, in even strokes.

It’s vital the person cleaning the house siding wears safety goggles to avoid blowback. Ensure all the windows are firmly closed. If there are any outlets on the outside walls, it’s required that the breaker be shut off and the outlet protected from the liquid. If not, that side of the home should not be sprayed. Stay at least three feet away from what is being cleaned to stay drier and safer.
