How to Clean Vinyl Siding

Introduction

Vinyl siding collects dirt, pollen, mold, and mildew over time, leaving your home looking dull or stained. With the right tools and cleaning method, you can restore your siding’s appearance and help extend its lifespan.

What You'll Need

• Soft-bristle brush or siding brush

• Garden hose with spray nozzle

• Bucket of warm water

• Mild dish soap

• White vinegar or oxygen bleach (optional for tough stains)

• Siding-safe cleaner (optional)

Steps

Rinse the siding with a garden hose to remove loose dirt and debris.
Mix warm water with mild dish soap (or vinegar for mildew) in a bucket.
Use a soft-bristle brush to scrub the siding gently, working from the bottom up.
Rinse thoroughly from top to bottom to prevent streaking.
Repeat on heavily soiled areas until the surface is clean.
Allow the siding to air dry completely.

Alternative Methods

• Use a vinegar-and-water solution (70% water, 30% vinegar) for mildew

• Apply an oxygen bleach solution for stubborn stains

• Use a siding-safe commercial cleaner with a hose attachment

What NOT to Do

• Do not use abrasive scrubbers that may scratch the siding

• Do not use undiluted bleach as it may damage the material
