How to Prevent Foggy Car Windows: Best 2 Products that really work

Foggy car window photo Don't drive without this - Best 2 products to keep your car windows from fogging up
If your car windows keep fogging up, like ours did, making it hard to see while you're driving, you need to read this post. 

Don't Drive Without This

One night while driving across a dark, snowy maintain pass, the snow and cold were so relentless, it kept fogging up our windshield to the point that the heater's defrost just could not keep up. All that was left to see through, was a small area on the windshield, which made for a very scary, dark and unsafe drive. 

Immediately after getting home, my husband started looking up products that could help us to never encounter that dangerous situation again. 

Thankfully, my husband was able to find and test 2 products that not only- 
  • help keep the windshield and other car windows clear from fogging up
  • but also minimizes the moisture inside the car 
We have never driven without these 2 products again. And because they worked so well at keeping our car windows from fogging up, I knew I had to share them with you! I hope they give you the same peace of mind (and added safety) they have given us. (*this post contains Amazon links. As an Amazon associate I make a small commission on purchases)

How to Prevent your Car Windows from Fogging Up (best 2 products that really work!)

1. Rain-X AF21106D Glass & Mirrors Anti-Fog Treatment, Prevents Fogging & Steaming on Windshield and Visors, Improves Visibility, Great for Auto & Home 
(*Amazon link)


This has to be my very favorite product for preventing foggy car windows and increasing safety while driving! You wipe it on the inside windshield of your car (+all the windows if you want to) and as if by magic, it keeps the windshield from fogging up! I am a HUGE FAN of all Rain-X products and this did not disappoint!!

2. Moisture Absorbers (Fragrance Free) (*Amazon link)


I was surprised by these little moisture absorbers. We've used them in closets before, where they worked well, but I never thought to put one in our car. Turns out, they work just as well in cars!

The filter draws in and traps excess moisture, over time the beads dissolve into liquid, and the moisture collects in the base of the container. Once all the beads have dissolved into liquid, you replace the container with a new one.

**I prefer the fragrance free moisture absorbers, but there are options for scents if you choose.


3. Chemical Guys Professional Grade Premium Microfiber Towels for Cars (Optional extra) (*Amazon link)

It's best to wipe the Rain-X anti fog on with a microfiber towel to prevent lint or scratching. This brand is a good one if you're looking for a few good quality cleaning cloths for your car.


Safety while driving is the # 1 priority for all of us, and now you can have the peace of mind to know your vision will never be compromised due to a foggy windshield.

These 2 products have helped us so much this winter, and are the perfect solution for preventing foggy car windows and excess moisture inside your car, which can help prevent unsafe driving conditions. 

Have you tried them? Let me know! I hope they help you as much as they've helped us!
