Before starting a pressure wash cleaning job, it is important to prepare the surface that is to be
cleaned. This is done by clearing the area of furniture, and making sure that all windows and doors are
closed tight. In addition, you should make sure that all plants and trees adjacent to the cleaning area
are protected by a drop cloth. This will ensure that your plants won’t be sprayed by the detergents.
The following cleaning procedure will help you to organize your cleaning task,
and ensure that you achieve the most beneficial results in the shortest amount of
time. Remember to use the spraying/cleaning techniques previously listed.
The next step is to spray the cleaning surface with water to clear off any dirt or grime that may have
collected on the surface. This will allow your detergent to attack the deep down dirt that has worked its
way into the cleaning surface. Before triggering the gun, adjust the nozzle to a wide fan pattern and
slowly adjust to the desired spray pattern. This will help you avoid applying too much concentrated
spray to the surface which could cause damage.
Start final rinse at bottom and work upward. Make sure you thoroughly rinse the surface and that all
detergent has been removed.
