Winter Windshield Cleaning Do’s and Don’ts

Updated: Dec 5, 2024

Winter can be harsh on your vehicle, and your windshield often takes the brunt of the season’s challenges. From frost to grime, maintaining a clear windshield is essential for safe driving. Here’s a step-by-step guide to cleaning your windshield safely and effectively this winter, along with common mistakes to avoid.


Do’s: Cleaning Your Windshield Safely


1. Use the Right Tools

Before you start, gather the proper supplies:


  • A soft microfiber cloth

  • An ice scraper with a plastic edge (avoid metal scrapers)

  • Winter windshield washer fluid

  • A de-icing spray (optional)

  • A squeegee (if available)


Avoid using abrasive tools or regular household cleaners, as they can damage the glass or leave streaks.


2. Start with De-Icing


If your windshield is covered in frost or ice:

  • Turn on the Defroster: Start your car and let the defroster warm the windshield. This loosens frost and makes scraping easier.

  • Spray a De-Icer: Use a store-bought or homemade de-icing spray (a mix of rubbing alcohol and water works well). Spray evenly and let it sit for a minute.

  • Scrape Gently: Use a plastic ice scraper at a shallow angle.


3. Clean Off Dirt and Grime


Winter roads often leave windshields dirty with salt and slush residue:

  • Spray Windshield Washer Fluid: Make sure to use a winter-specific fluid designed to resist freezing.

  • Wipe with a Microfiber Cloth: Gently clean the glass in a circular motion to avoid streaks.

  • Rinse with More Washer Fluid: This removes any leftover residue for a streak-free finish.


4. Don’t Forget the Wipers


Dirty or frozen wiper blades can damage your windshield:

  • Lift the Wipers: Before cleaning the glass, lift the wiper arms to prevent freezing against the windshield.

  • Clean the Blades: Wipe down the wiper blades with a damp microfiber cloth. If they’re worn or cracked, replace them to avoid scratches.


Don’ts: Mistakes to Avoid When Cleaning Your Windshield


1. Don’t Use Hot Water

Pouring hot water on a frozen windshield may seem like a quick fix, but it can cause the glass to crack due to the sudden temperature change. Always stick to gradual warming methods like your car’s defroster or a de-icing spray.


2. Don’t Scrape with Metal Tools

Metal scrapers or any hard objects can leave deep scratches or even chip the glass. Always use a plastic ice scraper designed for windshields.


3. Don’t Run Your Wipers on Ice

Turning on your windshield wipers to remove ice can damage both the wiper blades and the motor. Make sure the ice is completely melted or scraped away before using them.


4. Don’t Use Household Cleaners

Ammonia-based products like standard glass cleaners can damage your windshield’s protective coating and leave streaks. Always use products specifically designed for auto glass.


5. Don’t Neglect Small Cracks

Cold weather can worsen small chips or cracks on your windshield. Have them repaired as soon as possible to prevent further damage.


Prevent Future Build-Up


Proactive care makes cleaning easier throughout the winter:

  • Apply a Water Repellent: Use a windshield treatment like Rain-X to help water and ice slide off more easily.

  • Park Smart: Whenever possible, park in a garage or use a windshield cover to protect against ice and snow.

  • Top Off Washer Fluid: Regularly check your washer fluid levels to ensure you don’t run out when you need it most.


Stay Safe This Winter

A clean windshield isn’t just about aesthetics—it’s crucial for safe driving. By following these tips and avoiding common mistakes, you’ll ensure maximum visibility and protect your windshield from winter damage.
