Your home’s exterior is the first thing people see. A clean, well-maintained house not only boosts curb appeal but also protects your investment. But here’s the catch: one wrong move during exterior cleaning can lead to expensive repairs. From stripping paint to water damage, the risks are real.
Here are the top 5 mistakes to avoid in exterior cleaning and what to do instead to keep your house looking sharp without breaking it.
1. Using Too Much Pressure
Mistake: Cranking up the pressure washer to blast away dirt.
Why It’s Bad: High pressure can crack siding, strip paint, and force water under surfaces.
Better Way: Use soft washing techniques (low pressure with specialized cleaners) for siding, roofs, and delicate surfaces. Reserve higher pressure for hardscape like driveways and brick.
2. Skipping the Pre-Rinse and Soak
Mistake: Spraying chemicals or soap directly on dry surfaces.
Why It’s Bad: Stains and dirt won’t lift properly, and cleaning solutions may streak or leave residue.
Better Way: Pre-rinse surfaces to loosen debris. Let detergents soak for several minutes before rinsing, it allows them to actually break down grime.
3. Ignoring Safety Gear
Mistake: Cleaning in flip-flops and no goggles.
Why It’s Bad: High-pressure spray and chemicals can cause serious injuries or burns.
Better Way: Always wear safety glasses, gloves, non-slip shoes, and protective clothing. Don’t underestimate slippery surfaces.
4. Cleaning in Direct Sunlight
Mistake: Washing your home on a hot, sunny day.
Why It’s Bad: Cleaning solutions dry too quickly, leaving streaks and spots. Surfaces can also overheat, making it harder to rinse clean.
Better Way: Wash in the morning, evening, or on cloudy days for best results.
5. Forgetting to Protect Landscaping
Mistake: Spraying chemicals near flowerbeds and shrubs without protection.
Why It’s Bad: Many cleaning agents can kill grass, flowers, and plants.
Better Way: Cover landscaping with plastic sheeting or tarps, and rinse plants thoroughly before and after cleaning.
Exterior cleaning isn’t just about blasting dirt; it’s about doing it safely and effectively. By avoiding these common mistakes, you can protect your home’s surfaces, extend their lifespan, and boost curb appeal without costly damage.
