Step-by-Step Guide to Cleaning Vinyl Siding in Ohio

May 2, 2025

Vinyl siding is one of the most popular exterior materials for homes in Ohio—and for good reason. It's durable, low-maintenance, and attractive. But even the toughest materials need a little TLC. Knowing how to clean siding the right way can make a big difference in curb appeal and the longevity of your home's exterior.

At Kidron Custom Exteriors, we’ve worked with countless homeowners to help maintain and extend the life of their siding. Whether you're tackling spring cleaning or prepping your home for sale, here's a detailed guide on how to clean vinyl siding effectively and safely.

Why Cleaning Vinyl Siding Matters

Your siding takes the brunt of everything from snow and rain to wind and dust. Over time, this exposure can lead to:

Dirt and grime buildup
Mold, mildew, and algae growth
Fading and discoloration
Reduced energy efficiency (if buildup affects insulation)

Cleaning your siding once or twice a year helps prevent long-term damage and keeps your home looking its best. A clean surface is also the best starting point if you ever plan to repaint, repair, or replace your siding.

Step-by-Step: How to Clean Siding the Right Way

Step 1: Do a Visual Inspection
Before you start cleaning, take a few minutes to inspect your siding. Look for:

Cracks or loose panels
Warping or bubbling
Signs of mold or water damage

If you notice any of these, reach out to vinyl siding contractors in Ohio like Kidron Custom Exteriors. Catching problems early can save you from expensive repairs down the line.

Step 2: Start with a Rinse
Use a garden hose to rinse off loose debris, dust, and spider webs. Begin at the bottom and work your way up—this helps prevent streaking. Then rinse from top to bottom to wash it all away.

Step 3: Mix Your Cleaning Solution
You don’t need harsh chemicals to get your siding clean. Here’s a simple DIY mix:

70% water
30% white vinegar
A few drops of dish soap

This blend is gentle enough to avoid damage but strong enough to tackle most grime and mildew.

Step 4: Scrub Gently
Use a soft-bristle brush or a microfiber cloth on an extension pole. Work in small sections and scrub in a gentle, circular motion. Avoid abrasive scrubbers—they can scratch the surface.

Step 5: Rinse Thoroughly
After scrubbing, rinse each section thoroughly to avoid leaving soap or residue behind.

Optional: Use a Pressure Washer (with Caution)
You can use a pressure washer, but only at a low setting. Hold it at eye level and spray straight at the panel, not upward—this prevents water from getting behind the siding, which can lead to mold or rot.

Tips to Make the Job Easier

Avoid Cleaning in Direct Sunlight: This causes streaks and dries the cleaning solution too quickly.
Clean on a Mild Day: Too hot, and the siding dries too fast. Too cold, and mildew becomes stubborn.
Trim Landscaping Nearby: Overhanging trees and bushes can encourage mildew and trap moisture.

How Often Should You Clean Vinyl Siding?

For most homes, once or twice a year is plenty. However, if your home is in a wooded or humid area, you may need to clean more frequently to prevent mold and algae buildup. Some siding companies recommend spot cleaning throughout the year to tackle specific problem areas before they spread.
