A Guide for Power Washing Siding Safely & Effectively

A power wash is a great way to clean your home’s siding and make it look like new again. However, if you don’t do it correctly, you can damage your siding or even injure yourself. That’s why it’s important to follow these tips for power washing siding safely and effectively. With just a little bit of effort, you’ll have your home looking its best in no time!

Gather your supplies – you’ll need a power washer, detergent, and a brush or sponge:

Gather your supplies for power washing your siding before you get started. You’ll need a power washer to force the water onto your siding, thereby dislodging any dirt and debris built up there; a multipurpose cleanser that can tackle the dirt, grime and mildew built up over time; and a brush or sponge to help further break down tough spots. With these simple tools in hand, you are ready to begin the power washing process and leave your home’s siding looking as good as new!

Power Washing Siding

Set up your power washer according to the manufacturer’s instructions:

Before you start power washing your siding, ensure that the power washer is properly set up according to the manufacturer’s instructions. Make sure the pressure washer hose is securely connected, that all pressure gauges and safety switches are set appropriately, and that the detergent being used is compatible with the machine. Taking these steps will help ensure your project goes smoothly and minimizes any potential for injury or damage.

Wet down your siding with the power washer, starting from the bottom and working your way up:

Before you begin power washing siding, it’s important to wet it down with the power washer so that you can start from the bottom and work your way up. First, take your nozzle, keep it at least a foot away from the surface of your siding and apply a wide angle spray. Once you have the area moistened and ready for cleaning, switch to a narrow angle aimed at dirty areas and give them a thorough scrubbing for best results. Try to avoid putting too much pressure on soft surfaces and be sure to rinse all cleaned sections as you work in order to avoid soap residue buildup. 

Apply detergent to any areas that are particularly dirty:

Prior to power washing, it is important to properly treat any areas that are particularly dirty. Applying detergent to these soiled spots not only ensures that dirt and grime will be more easily removed during power washing, but also allows for the siding to be more thoroughly cleaned. Additionally, this process will reduce any likelihood of discoloration or staining due to large accumulations of dirt or debris. Cleaning these problem areas with detergent before power washing ensures a thorough clean and lasting shine.

Rinse off the detergent with the power washer:

When power washing siding, it is important to remember to rinse off the detergent that has been used. This should be done with a power washer set to a low pressure level to avoid causing any damage to the siding. After allowing the detergent to sit for a few minutes, use a steady stream of water from the power washer in order to effectively rinse away all traces of the detergent and any dirt that has been dislodged. Following these steps will leave your siding clean and looking practically new.

Let your siding dry completely before applying any sealants or paints:

No matter how tedious it can be, it is essential to ensure that your siding is fully dry before applying any sealants or paint. The process of power washing siding clears away dirt and debris, but in the process large amounts of moisture are created as well. As such, it’s important not to make the mistake of rushing ahead and immediately sealing or painting your newly cleaned siding; this could lead to bubbling, peeling, and other unsightly consequences that weaken the integrity of your siding. Instead, allow at least 48 hours for a thorough drying before pursuing the next step in your project!
