De-icers

You're running late, and your windshield is covered in thick ice. Your scraper barely makes a dent. Canadian winters bring snow, sleet, freezing rain, and temperatures that can reach -40°C and below-sometimes all on the same day.

Luckily, there is a way to save time scraping or defrosting your windshield. Learn how different windshield de-icer options can safely and effectively clear built-up ice for crystal-clear vision before your next drive.

How Do Windshield De-Icers Work?

Windshield de-icers use methanol-based formulas that lower the freezing point of water. They have a much higher antifreeze content compared to typical windshield washer fluids, so they have a lower freezing point and effectively break down ice on contact.

Most formulas have a temperature rating that ranges from -40°C to -49°C. So, always check the label, because a de-icer must have a lower freezing point than the temperature outside for it to be effective.

Why Are Windshield De-Icers Essential for Canadian Winters?

Weather conditions can become quite cold and icy from October to March for many drivers across Canada. Rapidly changing road conditions can lead to reduced traction and poor visibility, so drivers need to be even more alert.

A windshield free of ice help guarantee that every winter road trip is safe. In addition, provincial and territorial laws may expressly prohibit driving with impeded vision.

What Are the Different Types of Windshield De-Icers?

There are many application options- however, all windshield de-icers improve visibility without the heavy scraping. Here's a breakdown of your options.

Spray De-Icers

Spray de-icers deliver concentrated formulas in an aerosol spray bottle for quick and simple application. This type of windshield de-icer melts heavy ice without having to use the wipers or wait for your vehicle to defrost.

Due to its quick results, this is an ideal option for emergency situations or on extremely cold mornings when your windshield washer system is frozen.

Windshield Washer De-Icer Fluids

Winter windshield washer de-icers use the same type of fluid as spray de-icers and come with the same temperature ratings.

However, they differ considerably from summer windshield washer fluid, which includes only a small amount of antifreeze to help on cold nights. Summer windshield washer fluid's main goal is to get those flattened bugs off your windshield.

Keep an eye out for de-icer washer fluids with non-smear formulas, salt and ice removal technology, and water beading to improve wet weather visibility.

Lock De-Icers

Ice doesn't just affect your windshield. Sub-zero temperatures can cause car door lock mechanisms to freeze as well. Lock de-icers instantly de-freeze and lubricate internal lock mechanisms. Products can come in small bottles, e.g., 35 mL, making them a convenient on-the-go choice for older vehicles without remote keyless entry.

Just remember to keep lock de-icer somewhere accessible, like your pocket, purse, or coat, and not in your locked vehicle.

How Do I Choose the Right Windshield De-Icer?

Always start your buying process by matching the de-icer's temperature rating to your region's typical winter lows. For example, de-icers with a temperature rating of -40°C are ideal for regions with milder winters, like Southern Ontario or coastal British Columbia. Drivers living in regions with prolonged and bitterly cold winters, like the prairies and northern regions, should opt for -45°C to -49°C protection.

How Do I Use Windshield De-Icer?

Before switching from a summer windshield washer fluid to a de-icer formula, make sure you empty your reservoir to avoid dilution. You can also improve the performance of a de-icer on extremely cold days by running your engine with the heater on to help warm your windshield before application.

Even once you're on the road, try to keep your heater on your windshield to ensure your de-icer formula can continue to do its job.

Learn how to properly refill your windshield washer fluid and check fluid levels monthly during winter, since salty roads can quickly deplete your washer fluid.

What Safety Precautions Should I Take When Using Windshield De-Icers?

Always follow all manufacturer safety precautions on the product before and after handling windshield de-icer. Avoid sparks and flames, use in a ventilated area, and wash hands after application to avoid ingestion.

Always keep a bottle of windshield de-icer and an ice scraper in your vehicle for winter- never use hot water to clear ice.

Never substitute water for windshield washer fluid. It won't clear your windshield properly. If water freezes, it can seal your doors, handles, and windows shut and even damage your tank and fluid lines.

Which Winter Accessories Should I Use with a De-Icer?

Windshield de-icers work best when combined with winter-specific parts and tools. That includes using winter wiper blades that can handle ice and snow and snow brushes and ice scrapers designed for use on a vehicle.

One last word: never use metal to remove ice on on any part of your vehicle. You'll risk scratching it, which can give rust and cracks a chance to form.
