How to Clean Vinyl Siding
Keep Your Home’s Exterior Looking New
Vinyl siding is one of the most popular exterior materials for homes in Connecticut thanks to its durability, affordability, and low maintenance. However, like anything exposed to the elements, it needs occasional cleaning to stay in top shape. This guide from
Bartlett Contracting, LLC will walk you through how to clean vinyl siding safely and effectively — and when it might be time to call in the professionals.
Why Cleaning Vinyl Siding Matters
Over time, vinyl siding can collect dirt, mildew, mold, pollen, and spider webs — especially in shaded or damp areas. Cleaning helps:
- Preserve your home’s curb appeal
- Prevent permanent staining or discoloration
- Maintain property value
- Extend the life of your siding
Ignoring routine cleaning can lead to long-term damage that’s expensive to repair.
Best Time to Clean Vinyl Siding in Connecticut
Spring and early fall are ideal for siding maintenance in New England. These seasons offer moderate temperatures and minimal pollen. Avoid cleaning during freezing conditions or when direct sunlight could dry the cleaning solution too quickly.
Supplies You Will Need
Before getting started, gather these basic tools:
- Soft-bristle brush or long-handled brush
- Garden hose with spray nozzle
- Bucket
- Mild detergent or vinyl siding cleaner
- Optional: white vinegar, baking soda, or oxygen bleach for tougher stains
- Optional: Pressure washer (low pressure only — more on that below)
Step-by-Step Cleaning Process
- Inspect Your Siding
Look for damage, cracks, or loose panels. Make repairs before cleaning to avoid water getting behind the siding. - Rinse with Water
Start at the bottom and rinse upward to prevent streaks, then rinse downward to wash everything away. - Apply Cleaning Solution
Mix water with mild soap or a vinegar solution (70% water, 30% vinegar). Use your brush or sprayer to apply it evenly. - Scrub Gently
Use a soft-bristle brush on any particularly dirty areas. Avoid scrubbing too hard, which can scratch the siding. - Rinse Thoroughly
Rinse with clean water, working from top to bottom. Don’t let cleaning solution dry on the surface. - Let It Dry Naturally
Let the siding air dry fully before inspecting your results or applying any follow-up treatment.
Can You Use a Pressure Washer?
Yes — but with caution. Vinyl siding can be cleaned with a pressure washer
at low pressure (typically under 1,500 PSI). Hold the nozzle at eye level and spray straight-on to avoid forcing water behind the panels. Always check the manufacturer’s instructions, or contact a professional if unsure.
Stubborn Stains and Mildew? Try These Solutions
- Mildew & Mold: Use oxygen bleach (not chlorine) mixed with water
- Grease or Oil: Try a diluted solution of dish soap and water
- Rust Stains: Use a non-abrasive cleaner specifically made for rust
Avoid harsh chemicals, abrasive scrubbers, or undiluted bleach — these can damage your siding and landscaping.
A Little Maintenance Goes a Long Way
Cleaning your vinyl siding once or twice a year keeps your home looking great and helps avoid premature repairs. Whether you choose to DIY or hire a pro, proper care ensures your siding lasts — and keeps adding value to your home for years to come.
