When it comes to cleaning the exterior of your home or business, pressure washing can seem like a miracle solution. It’s fast, powerful, and effective—for the right surfaces. But pressure washing the wrong materials can lead to expensive damage, safety risks, and long-term deterioration.
At So Clean Solutions, we’ve seen it all—and we’re here to help you avoid costly mistakes. Here are 10 surfaces you should never pressure wash, and what we recommend instead.
1. Asphalt Shingles
Why Not: Pressure washing can strip away the protective granules, loosen shingles, and reduce the lifespan of your roof.
✅ What to Do Instead: Hire a professional soft wash service that uses low-pressure water combined with eco-friendly cleaning agents to gently clean without damage.
2. Old or Painted Wood
Why Not: High-pressure water can strip paint, splinter wood, and cause water intrusion that leads to mold or rot.
✅ What to Do Instead: Use a soft wash system or hand wash with a wood-safe cleaner. Let professionals assess the condition before any cleaning begins.
3. Brick with Damaged Mortar
Why Not: Pressure washing can further erode crumbling mortar joints, causing structural issues or leaks.
✅ What to Do Instead: Use a low-pressure rinse and specialty masonry cleaners applied by trained technicians.
4. Windows
Why Not: High pressure can break seals, crack glass, or push water into the interior of your home.
✅ What to Do Instead: Use a gentle window cleaning method with soft brushes and purified water for a streak-free finish.
5. Electrical Panels and Meters
Why Not: Spraying high-pressure water near electrical components is dangerous and can short-circuit systems.
✅ What to Do Instead: Carefully clean around these areas by hand, or let trained technicians use safe, low-moisture cleaning techniques.
6. Air Conditioning Units
Why Not: The fins and coils are delicate and can easily bend or break under pressure.
✅ What to Do Instead: Turn off the unit and gently rinse with a hose or use an AC-specific coil cleaner.
7. Stucco and Dryvit (EIFS)
Why Not: These surfaces are porous and fragile, making them vulnerable to cracking or internal moisture damage when pressure washed.
✅ What to Do Instead: Soft washing with low-pressure water and a biodegradable cleaning solution is ideal for these finishes.
8. Lead Paint Surfaces
Why Not: Pressure washing can aerosolize toxic lead dust, posing health and environmental hazards.
✅ What to Do Instead: Work with certified lead abatement professionals who follow EPA guidelines for safe removal or containment.
9. Vehicles
Why Not: Pressure washers can chip paint, dent panels, and damage seals or electronics.
✅ What to Do Instead: Use a standard automotive wash or professional detailing service.
10. Outdoor Light Fixtures
Why Not: They often aren’t waterproof against high-pressure spray and can be damaged or filled with water.
✅ What to Do Instead: Clean gently by hand using a microfiber cloth and a mild cleaner, with the power off.
