How to Safely Clean Your Home’s Siding in Pittsburgh Without Damaging It
Introduction
In Pittsburgh’s diverse climate—where homes face heavy rain, snow, and humid summers—your home’s siding takes a beating. From green algae to black mold streaks, dirty siding can affect not only your home’s appearance but also its longevity. But how do you clean it without causing permanent damage?
At D & L Landscaping and Exterior Cleaning, we help homeowners across Pittsburgh safely and effectively restore their siding. This guide walks you through the safest techniques and insider tips for maintaining a clean, beautiful exterior.
Why Siding Gets So Dirty in Pittsburgh
Pittsburgh's four-season climate creates a perfect environment for dirt, mold, mildew, and algae to grow—especially on north-facing walls that receive less sun.
Common culprits include:
- Air pollution from industrial and traffic emissions
- Tree sap, pollen, and leaves from nearby foliage
- Humidity and moisture, especially in spring and summer
- Snow and ice runoff during Pittsburgh winters
All of these build up over time, leading to stains, discoloration, and in some cases, permanent damage to your siding material.
Safe Cleaning Methods for Different Siding Materials
1. Vinyl Siding
- Low-pressure rinse (under 1,500 PSI)
- Soft wash solution: mix water, bleach (optional), and mild detergent
- Soft bristle brush for tougher areas
Avoid aiming upward at seams—that’s how water gets behind the panels.
2. Wood Siding
- Use very low-pressure spray
- Apply oxygenated bleach or wood-safe cleaners
- Follow with a protective wood sealant to prevent rot
3. Fiber Cement Siding
- Use a wide-angle spray tip
- Choose non-acidic, siding-safe cleaners
- Rinse gently and completely
Step-by-Step: How to Clean Your Siding Safely
- Inspect First: Look for cracks, mold, loose panels, or water damage. Don’t clean until repairs are done.
- Pre-rinse the Siding: Spray down with garden hose or low-pressure washer to loosen surface grime.
- Apply Cleaning Solution: Use a pump sprayer or soft-wash system to apply a siding-safe detergent.
- Scrub Gently: Spot clean with a soft brush on stained or moldy areas. Don’t scrub too hard—especially on older siding.
- Rinse Thoroughly: Use wide-angle spray from top down to rinse away residue.
- Let It Dry Naturally: Choose a sunny, dry day so the siding dries quickly and thoroughly.
Common Siding Cleaning Mistakes to Avoid
- Using High Pressure on Soft Siding
- Skipping the Cleaning Solution
- Ignoring Safety Gear
- Cleaning in Direct Sunlight
