Step-by-Step Guide to Cleaning Your Vinyl Siding

Winter can leave your vinyl siding looking a little worse for wear. Dirt, grime, and even mold can build up over the cold months, making your home’s exterior appear dull. But don’t worry! With some simple steps and a bit of elbow grease, you can have your siding looking fresh and welcoming in no time. Here’s how to clean your vinyl siding after winter like a pro from our JM Roofing team.

1. Inspect Your Siding

Take a walk around your home and inspect the siding. Look for damage, such as cracks, loose panels, or discoloration. If you spot issues, fix them before cleaning to prevent further wear and tear.

2. Rinse Away Loose Dirt

Start by spraying your siding with a garden hose to remove loose debris like dirt, leaves, or cobwebs. Work from the top of the siding down to avoid streaking and ensure all grime washes off effectively.

3. Mix Up a Cleaning Solution

For most siding, a bucket of warm water with a few drops of dish soap does the trick. If your siding is particularly dirty or moldy, use a cleaner specifically formulated for vinyl siding, which you can find at your local hardware store.

4. Scrub Gently

Dip your brush into the cleaning solution and gently scrub the siding, focusing on areas with visible dirt or stains. Always scrub in a horizontal motion rather than up and down to avoid damage to the panels. For stubborn spots, dip your brush in soapy water and apply a little more pressure—but not too much! You don’t want to have to replace your siding

5. Rinse Thoroughly

After cleaning a section, rinse it immediately with your garden hose to prevent soap residue from drying on the surface. Again, work from top to bottom for the best results.

6. Tackle Mold and Mildew

If you notice green or black spots from mold or mildew, mix one part white vinegar with three parts water. Apply the solution to the affected area, scrub gently, and rinse thoroughly. Vinegar is effective yet safe for the environment and your siding!

Safety Tips

  • Always use a sturdy ladder if you’re working at height, and never overstretch yourself.
  • Wear gloves to protect your hands from cleaning solutions and dirt.
  • Avoid using pressure washers, which can force water behind the siding and cause damage.
