These eight techniques range from free to low-cost products. You’ll have prevented your window from fogging up by the end of this post.
Having a good heater in your car is one of the finest things to have in the winter. Heat makes everything more delightful, especially while driving. One of the most serious drawbacks is when the heat inside the car causes the windows to fog up, making it impossible to see the road.
How to Stop Windows Fogging up in Car?
Here’s how to keep your windows from fogging up during the winter. These ideas are applicable to vehicles, trucks, and even winter camping in RVs.
Step #1. Clean Your Windows
One of the first things you should do is make sure your windows are clean and have no residue on them. Typically, dirt from the road and the environment gets on the windows when driving. Dirt traps both moisture and heat, creating an ideal environment for foggy windows.
Keeping clean windows is more critical than ever during the winter. The dirt will not only make it easier for the fog to form on your window, but it will also turn the fog a dirty colour, making it difficult to see through the window with the fog build-up.
When trying to clean your windows in the winter, make sure they are completely dry before you leave the car. If there is any water residue left on the glass, it may freeze, making removal difficult in the morning before leaving for work.
Step #2. Apply Anti-Fog Spray to Stop Windows Fogging up in Car
The anti-fogging spray was developed to prevent fogged-up window shields, which are ubiquitous. This spray may have already been used by people who wear glasses.
It is intended to be a simple remedy that consists of simply spraying the window and letting the spray prevent fog from developing and being formed.
Anti-fogging spray is available in your local grocery, mechanical store, or online. You could use Rain-X Interior Glass Anti-Fog Spray. This brand has worked well for us in preventing water drips on our GoPro cameras.
Step #3. Recirculation should not be used
Check the recirculation button on your fan system if your windows are fogged up more than usual. When you recirculate the air, moisture accumulates and begins to condense on the interior glass.
Instead, turn on your fan to bring in the fresh air. This fresh air will be cold and, as a result, dry, especially in the winter. This will aid in keeping your windows clear.
Step #4. Use Air Conditioner with Hot Air
Although it might be tempting to get in your car and blast the hot air, this produces instant heating of the interior, raising humidity levels and causing the fog to form.
Instead, turn on the hot air to simultaneously warm the vehicle and the air conditioner. The air conditioner will dry out the air. You’ll get the best of both worlds. A toasty automobile with a dry, clear window to look out of. Warming up your car beforehand might help decrease window fogging by giving the inside more time to warm up.
You also don’t have to be concerned about getting cold because of the air conditioner. Your heat will overpower your air conditioner, resulting in clear windows and a heated vehicle. I’ll leave you with Scotty Kilmer’s explanation of this strategy. He has a lot of energy and is quite enthusiastic about auto maintenance.
Step #5. Clean Your Shoes and Coat
The humidity is to blame for your fogged-up windows. The fogging of your windows is a natural process caused by humidity and moisture. Condensation will form on the glass, much like it would with a cool drink of lemonade on a hot day. Remove some of the humidity in your vehicle to assist stop the fogging-up process.
One piece of advice found on this site about condensation removal is to shake snow and slush off your shoes prior to entering your vehicle. Additionally, attempt to air-dry your coat or any other outer clothing layer. This will remove any excess water and humidity from your vehicle.
Step #6. Buy a Silica Dehumidifier
Silica dehumidifiers function similarly to silica packets in clothes. When you buy new clothing, silica packets are frequently placed in shoes and garment boxes to eliminate any dampness and water from the clothing.
For clothes merchants, this is to prevent mould from forming due to humidity trapped in a clothing box. Silica dehumidifiers can provide the same function in your vehicle.
This is available in a jar or in small bags that may be placed in your vehicle to absorb any dampness.
Money Saving Tip: If you’re looking for methods to save money, save the little silica packets from garments and shoes and make your own. To reduce humidity, you can either place those packets on your dashboard or in a small cup in your cup holder.
They are, however, not expensive if you want to save yourself the effort. These are reusable and reasonably priced. Zarpax’s 2-pack is an excellent choice.
Caution: Although silica is particularly good at removing moisture, it should be kept out of the reach of children. If ingested, call 911 immediately. If your children are always in the car with you when you drive, consider buying or making fabric-enclosed bags to store the silica in.
Step #7. Clean Up Any Liquid in Your Car
Similarly to advice number 5, removing any liquid from within your vehicle will aid to lessen the quantity of humidity located inside and cause foggy glass. Leave no drinks in your car because the liquid will cause dampness.
While it may be difficult, avoid drinking hot chocolate, tea, or coffee in your car during chilly weather, as this is a formula for foggy windows. Because heated air holds more humidity, bringing in a hot drink contains all of the components for an impossible-to-see-through, foggy window.
Step #8. Shaving Cream
As an alternative to using Rain-X, you may try wiping shaving cream on the glass. This strategy is tested and illustrated below.
Step #9. Using Kitty Litter to Stop Windows Fogging up in Car
Kitty litter, like silica, absorbs moisture and holds it in place. Buying some clean and dry kitty litter is a do-it-yourself (DIY) tip for reducing window fogging throughout the winter. Fill an old sock up to the ankle with kitty litter. Then, knot the sock off. If you’re using an ankle or short sock, you’ll need to use a rubber band or string to secure it completely.
Tie the sock around itself or tie it off the similar way you would an ankle sock for knee-length socks. While parked, place these kitty litter-filled socks on your dashboard to reduce window fog. This idea does not appeal to me because it will most likely leave dust on the dash. But in a pinch, it might suffice.
Step #10. Contact a Mechanic to Stop Windows Fogging up in Car
If you have excessive fogginess in your windows, there could be a crack or leak someplace in your vehicle that is allowing extra humidity in. It could also suggest a problem with the compressor in your air conditioner. A mechanic should be able to assist you in locating the problem and resolving it.
Keep in mind that foggy windows are common, but if you’ve tried everything and still have a lot of fogginess, it’s time to see a mechanic.
In conclusion, windows fogging up in a car can be a frustrating problem, but there are several effective ways to prevent it. Maintaining a comfortable temperature inside the car, keeping the windows clean and dry, and reducing the humidity levels can all help prevent window fogging.
Additionally, using anti-fog products or homemade solutions such as vinegar or shaving cream can also be effective in preventing window fogging. By taking these steps, drivers and passengers can enjoy clear and safe visibility while driving, even in humid or wet conditions. It’s essential to take preventive measures to avoid potentially dangerous situations while driving, and preventing window fogging is a crucial step towards achieving that.
