Prepare the Area:
Make sure that plants, fixtures, and windows are covered up. Remove any nearby furniture or appliance. Inspect the area to see if there are issues that first need to be addressed.
Apply Cleaning Solution:
Fill the pressure washer’s detergent reservoir with a bleach-based cleaning solution. Spray the solution onto the vinyl siding. Allow it to sit for a few minutes to loosen up all the dirt, stains, and buildup.
Pressure Washing:
Use the pressure washer to clean the vinyl siding. Start with a small section and continue working your way through the different areas. Pressure: Use a maximum of 3,000 PSI when cleaning vinyl siding. Consider starting at 1,000 PSI and gradually increase pressure. This will minimize potential damage to your vinyl siding while providing optimal results.
- Pressure: Use a maximum of 3,000 PSI when cleaning vinyl siding. Consider starting at 1,000 PSI and gradually increase pressure. This will minimize potential damage to your vinyl siding while providing optimal results.
- Nozzle: Consider using a 25-degree nozzle. Switch to a wider angle if you want less pressure on the vinyl siding.
- Sweeping Motion: Have the nozzle do a sweeping motion — working its way from top to bottom then left to right. This is to avoid unsightly streaks
- Angle: Only use a straight or slightly downward angle. Never clean the vinyl siding on an upward angle. This will cause water to go inside the siding, leading to significant damage and costly repairs. Use a ladder when cleaning hard-to-reach areas.
Rinse Surface:
Once all the dirt, stains, and buildup have been removed, rinse the surface with clean water. Switch to a 40-degree or fan spray nozzle and lower PSI to 1,000 to 2,000. This is to wash away all contaminants and cleaning solutions. Spray the nozzle from top to bottom to prevent streaks from forming.
Allow to Dry:
Give the vinyl siding time to dry off.
Regular Maintenance:
Regular pressure washing is the best way to maintain the appearance of vinyl siding, as well as to extend its lifespan.
