When to Clean Vinyl Siding With a Pressure Washer

There is a misconception that it is damaging to the vinyl siding to clean it with a pressure washer.  That is simply not true!

Without using this tool correctly, you could very well do damage to your home or apartment.  It is incredibly dangerous to use any machine without training and a pressure washer is no exception.

What you will Need

*NOTE: Soap and water will do the job just fine but using a pressure washer detergent is always better.  It will be guaranteed not to have any ingredients that could damage parts of the pressure washer.

  2. Spray the soap mixture on your siding. **
  3. If it has been awhile since you cleaned your siding, use a rotating or utility brush on the end of your pressure washer to get those hard to clean spots.

  5. Rinse your vinyl siding, making sure not to spray any eavestroughs or light fixtures.
  6. Stand back and congratulate yourself on a job well done.


  • Pressure washers are powerful machines and you do not want to damage your vinyl siding.
  • Start on LOW PRESSURE and make sure you are a safe distance away – at least 5 feet! You can adjust the pressure as needed, but always start with it very low. 
  • To prevent streaking, start at the bottom and work your way up, like painting. Apply the soap in systematic strokes so you do not miss a spot!
  • Keep the angle of the wand down so you do not get water in under horizontal siding.
