How to Pressure Wash Vinyl Siding

Homeowners should be cleaning the exterior of their home each year to remove dirt, mold, mildew, and stains to keep their home and family safe. The quickest and most efficient way to get the job done is with power washing – but how does the cleaning process differ when power washing vinyl siding instead of brick?
There are a few things you should know before picking up that power washer and cleaning your vinyl siding.

First, Carefully Inspect Your Home

Do a walk-around of your home’s exterior as a way to map out your cleaning process and prevent any damage. If you spot any cracks or broken parts of your vinyl siding, repair them if you’re able, or make sure to avoid those spots when power washing.
If you notice any areas of your siding that are extremely dirty, check to see if there’s a likely cause, such as a broken or leaking gutter, and fix the issue before continuing. If you don’t fix the issue before power washing, it could get worse.
If you find any areas that have thick layers of stained green algae or dirt, take a stiff bristle brush to the area so you don’t have to increase the pressure of the power washer, which could crack your vinyl siding

Pressure Washer Power Settings

When you’re about to pressure wash siding, you need to make sure the setting on the pressure washer is correct. This is probably the most important thing you’ll need to remember. The setting you use when pressure washing the siding of the home is dependent on the material of the siding. If a setting is too high, then the siding can break or be dislodged from the home. Vinyl siding can withstand more pressure than wood, but metal surprisingly is the weakest of the three and can dent. So a good rule of thumb is to use a medium setting.

Stream Settings

Power washing siding on a multi-level home is more difficult than a standard home. This can be done easiest by choosing the right setting for the stream of water. Not all pressure washer units have the ability to select the type of stream to use. The best stream to use on this type of home is a fan setting. This stream of water is narrow near the wand but widens at the end. This covers a larger area of the siding.

Direction of Water Stream

When you use a power washer to clean siding, you have to keep the direction of the water in mind. How the water flows also hinges on the material, the siding is made from. If you are using a strong stream of water, you always want to have the water flowing down the siding. In a multi-level home, you will need to get the top-level first. Then, the water will cascade down to the other levels. As you clean, you will be moving from side to side and gradually moving the wand down. If you are using water power and a half or as a fan, you can hit the siding from the bottom of the lip. This will get in the grooves of the siding.


Depending on how dirty the siding is, you can add detergent to some power washers. This will make power washing the siding go smoother as the dirt will be cut through easily. Just remember to rinse off with clean water.
