Choose Your Savings
Pressure washing a deck or fence is much more manageable and efficient than scrubbing by hand. These tips will get your cleaning project started.
Different models of pressure washers have different capabilities. Read the documentation that came with your pressure washer before beginning any cleaning task to make sure your model is appropriate for the job.
Some general tips for cleaning decks and fences are below, but always follow your pressure washer manufacturer's instructions for use, maintenance and safety.
Before you begin, get the work area ready:
You also need to make sure you have a suitable location for your pressure washer while you're cleaning. Take prevailing winds and air currents into account.
Determine the recommended spray pattern and / or spray tip for the job. This information should be in your pressure washer manual. You'll use different settings for applying the cleaner and for the actual high-pressure cleaning.
Do not run a gasoline-powered pressure washer indoors or in an area that does not have proper ventilation. Keep the engine exhaust away from occupied areas.
Read and follow all of the manufacturer's safety instructions for your pressure washer. General guidelines include:
Follow the pressure washer manufacturer's instructions on the type of wood cleaner to use and the distance the spray tip should be from the surface you're cleaning. For the best results, test the spray pattern and distance on an inconspicuous area of the deck or fence before cleaning. Also, test the high-pressure spray on a hidden area to make sure the setting does not damage the surface.
Applying the Cleaner
Spraying Off the Cleaner
After you've sprayed off the cleaner, let the deck or fence dry for 48 hours. Apply a stain or sealer according to the manufacturer’s instructions.
Once you've completed your cleaning project, follow the pressure washer manufacturer's instructions for relieving water pressure, removing liquid from the pump and proper storage.
Do not operate the pressure washer pump without the water supply connected and turned on. Your manual may specify letting the pressure washer rest after every few minutes of use.
