Plus Tips, Tricks & How All Sleek Services Can Help

Your home's exterior is its first impression—and dirty siding can make even the nicest house look neglected. Whether you’re noticing green streaks, dark stains, or a dull finish, it’s time for a siding cleanup. Here’s what those stains actually mean, how to clean them, and how a professional service like All Sleek Services KC LLC can make the process hassle-free.

🌿 What Is That Green Stuff on My Siding?

If your siding is turning green, black, or brown in spots, it’s most likely algae, mildew, mold, or dirt buildup. Here’s a quick breakdown:

Green Algae – Common on north-facing walls or shaded areas. Grows in damp conditions.
Black Streaks – Could be mildew or mold, especially near gutters or downspouts.
Brown/Gray Film – Often a mix of dust, pollen, and pollution.

What it means:These organisms feed on dirt, moisture, and even some siding materials. Besides looking bad, they can slowly damage your siding, trap moisture, and lower your home’s value.

🧼 How to Clean Siding: DIY Tips

1. Start with a Gentle RinseUse a garden hose with a spray nozzle to loosen surface dirt.

2. Mix a Safe Cleaning SolutionCombine:

1 gallon warm water
1/3 cup powdered laundry detergent
2/3 cup household cleaner (like TSP or vinegar)

3. Scrub GentlyUse a soft-bristle brush or siding mop to apply the solution. Scrub gently to avoid damaging the siding.

4. Rinse ThoroughlyStart at the top and rinse downward to prevent streaks.

5. Avoid Power Washing Unless TrainedPressure washing is effective—but it can damage siding or push water behind panels if done incorrectly. Always test a small area first.

🧠 Pro Tips and Tricks

Clean on a cloudy day to avoid quick drying that causes streaks.
Use oxygen bleach instead of chlorine for eco-safe mold removal.
Always protect plants and windows when using cleaners.
Inspect your siding yearly and clean at least once every 12–18 months.
