Vinyl siding is a popular choice for homes across Greenville, SC thanks to its durability and low maintenance. Over time, dirt, mold, and mildew can build up, making your home look older than it really is. Pressure washing is a great way to restore your siding’s original shine, but if done incorrectly, it can cause serious damage.
Here’s how to safely pressure wash your vinyl siding. If this type of DIY project isn’t for you we’ll also tell you what to do if you’d rather leave it to the pros.
Step 1: Equipment
Before you start blasting away dirt, make sure you have the proper tools:
- A pressure washer with adjustable PSI (1,300–1,600 PSI is ideal for vinyl)
- A 25- or 40-degree spray nozzle
- Cleaning solution safe for siding (avoid bleach heavy mixes)
- A garden hose for rinsing
- Safety goggles and gloves
Avoid using a zero-degree nozzle—it can easily puncture or warp vinyl.
Step 2: Pre-Rinse the Siding
Start by spraying your siding with water from the bottom up. This helps loosen debris and prevents the cleaning solution from drying too quickly. Cover nearby plants or landscaping with plastic sheeting to protect them from runoff.
Step 3: Apply Cleaning Solution
Use a detergent specifically designed for vinyl siding. Most pressure washers have a soap dispenser setting or attachment. Apply the solution evenly from bottom to top to prevent streaks.
Let it sit for 5–10 minutes, but don’t let it dry.
Step 4: Rinse with Low Pressure
Switch to a 25- or 40-degree nozzle and rinse the siding from top to bottom in overlapping strokes. Keep the spray at a 45-degree angle and maintain a distance of at least 3 feet from the surface.
Tip: Always spray with the grain of the siding to avoid forcing water behind it, which can lead to mold growth.
Step 5: Repeat for Tough Areas
For stubborn spots, reapply cleaner and gently scrub with a soft-bristle brush before rinsing again. Avoid using metal brushes or high-pressure nozzles that can gouge or damage the siding.
