The Best De-Icing Products to Keep In Your Car 

With the winter months comes the annoyance of frost on your windshield, frustration from iced-up car door locks, and the nearly impossible task of keeping a clear view of the road. It’s unsafe to drive unless the snow and ice have been cleared from all of your windows, not just a small section scratched in the windshield, and it can also be a fineable offense if you’re pulled over without clearing your windows first.

Fortunately, there are plenty of products at AutoZone designed to prevent ice from interrupting your day. With de-icers starting at under $4, there’s no reason to let a bit of frosty Mother Nature keep you stuck at home.

These are seven de-icer products you should have in your car, and what to do to de-ice before you hit the road.

Best de-icer products every driver should have 

There are three areas to consider when getting rid of ice from your car before driving: exterior, interior, and doors. These seven products will help you clear your car as well as get into it, busting Old Man Winter’s best efforts. 

Prestone Ice Fighter Spray

The outside glass gets the worst of it, and ice cakes up quickly. To get rid of buildup, heavy or light, this Prestone Ice Fighter Spray cuts through in seconds. Simply sweep off any loose snow, scratch the ice with a scraper, spray the glass with a mist or stream of the deicing spray, and wait a few seconds. The wipers will take care of the rest.  

Mallory 26in Ice Scraper Brush

Get rid of ice from your exterior glass and sweep snow from the rest of your car before you head out. The Mallory 26-inch snow brush combines paint-safe bristles on one end and a sturdy plastic scraper on the other that won’t damage the glass.   

SubZero Lock De-Icer

One product to keep in your jacket pocket or purse rather than in your car is lock de-icer since it’s no good to you if it’s frozen in your car. A small tube of SubZero Lock De-Icer has 100 sprays in an aerosol tube to repel any ice and moisture in a door lock, letting your key turn freely. Plus, it lubricates the lock to prevent ice building up again.

ProElite Microfiber Cloths

Even in the throes of a cold spell, a car wash might be necessary. Prevent getting frozen out of your car by wiping the door jambs and weatherstrips off. These ProElite Microfiber Cloths will pull the water droplets away from the metal and rubber so your doors don’t get frozen shut.

Johnsen’s De-Icer

If there’s too much moisture inside your car, frost forms on the inner glass. A windshield deicer safe for interior glass is a great option, like Johnsen’s De-Icer. It will also prevent fogging after it’s been applied to keep your glass clear.

Kat’s 150 Watt Interior Heater

If you want the convenience of clear windows AND a warm car interior, an auxiliary interior car heater is a great choice. Kat’s 150 Watt Interior Heater is a ceramic heater that plugs into your car’s 12-volt power outlet and warms the interior while melting the frost and ice from the inside. While it might not completely clear your exterior glass like a car deicer spray, it can soften it to make it easier to scrape off.

How to De-Ice Your Car 

Perhaps you’ve seen life hacks like a hot water-filled bag rubbed across a frosty windshield. While it might work for a tiny layer of frost, it’s not likely to stay hot long enough to clear all your glass. So, then, what are some tips for how to deice a windshield and the rest of your car? 

  • Park protected. Prevention is the best policy, if possible. If you’re able to park in a garage or a covered car park, you can prevent precipitation from freezing to your car. Then all you have to think about is clearing the frost that accumulates overnight. Obviously, that’s not always possible for every driver.  
  • Prep the glass before it freezes. It’s surprising how firmly ice grips to glass and other surfaces. A pre-emptive application of spray for de-icing windshield glass makes it much easier for any frozen substances to lift off the glass, if they stick at all.  
  • Crank the heat on the defrost setting. If there’s a serious layer of ice on your windows, inside or out, let your car heater do the prep work. Start the engine, set the HVAC controls to defrost, and let the heat begin to melt the ice. Then, finish the job with an ice scraper. A reminder: do not leave the engine running with the keys in the ignition when you aren’t in the vehicle! 
  • Remove the snow first. Make the job as easy on yourself as possible. Before tackling ice on the glass, sweep the snow off. Otherwise, the snow will keep melting and reforming into ice, making the job longer and harder. 
  • Let the de-icer spray do the heavy lifting. It takes a few minutes for a de-icer spray to cut through and melt ice off. Sometimes more than one application is necessary too. If you’re struggling to get the ice off of your car after the first spray, give it another shot and wait a few more minutes. 

Winter driving can be annoying, but it can be done safely if you clear your car of ice first. Shop at AutoZone for windshield de-icing supplies and other detailing and cleaning products today.
