Pressure washing is a quick and easy way to clean many outdoor surfaces, including your vinyl siding. But it comes with drawbacks. Too much water pressure can force water between the siding planks.

Hold your power washer wand straight out to keep the water on top of the siding where it can clean most effectively. Do not aim it upward as that's when water could get behind the siding. Always follow the siding manufacturer’s recommendations. Some don’t want pressure washers used on their products at all. Others have limitations on the amount of pressure that can be used.

Experts caution against the use of pressure washers around any opening in the wall, such as windows, doors, electrical wiring, and plumbing that could be affected by the water's force.

Remember to cover your plants before pressure washing so they will be protected. Also, select eco-friendly cleaners to use in the pressure washer to avoid harm from run-off chemicals leaching into the soil.
