How to Deice Windshields

By Andi Breitowich 1.5.26

If the thought of waking up bright and early to a frosted windshield brings a shiver down your spine, welcome to the club. It’s not a fun way to start the day, especially when you’re in a rush and least expecting it. 

But here’s the thing: When the temperature drops and winter sets in, it’s more important than ever to prepare yourself for the unruly Texas elements. Fortunately, there’s a variety of simple tips and tricks to effectively fight off the ice on your windshield so you can safely hit (and see) the road.

How to Deice Your Windshield

Step 1

Start your engine and hit the defrost button. Set the temperature control to the hottest setting and the fan to maximum speed to gradually heat the glass from the inside out. 

Step 2

Use a soft bristle brush to clear the ice as it melts from the windshield and roof to prevent it from sliding into view as you drive. Clear the grill just below the windshield to ensure you get the most from the heater and defroster.

Step 3

If the ice is thick, spray deicing fluid, such as Rain-X, from about 10 inches away. Don’t buy into DIY solutions involving hot water, salt, vinegar, and the like. These home remedies can eat away at the car’s paint and leave pits or cracks in the glass.

Step 4

Lift the wiper blades off the glass before using a plastic ice scraper to chip away at the ice. Start in the lower corner and work your way up. 

Step 5

Once the ice has been completely removed and/or melted, it’s safe to run the wipers.

How to Prevent Ice Buildup

Ice buildup on your windshield is sometimes unavoidable, but the following measures can help minimize the chances and risk of damage.

Park Strategically. If you have a garage, carport, or awning, take advantage of it. Keeping your car shielded from the elements is key.

Use a Windshield Cover. Place it over the window at night and peel it off in the morning. 

Apply Anti-Ice Treatment. Products such as Rain-X and B’laster repel water, helping it roll off the windshield and preventing (or reducing) ice bonding to the glass. 

Lift Your Wiper Blades. To prevent them from freezing to the windshield and causing damage, do your best to always lift the wiper blades when parked. 

Double-Check Your Washer Fluid. Some washer fluid is prone to freezing on the glass when the temperatures drop, so ensure you have a winterized fluid ahead of the colder months.
