To avoid blurry front windshields and side mirrors during rain or snow in 2025, you must manage both internal condensation and external water buildup using a mix of climate control settings and protective coatings.
1. Internal Defogging (The “Blurry” Inside)

These simple tips can save your life and your vehicle make sure to read all the following tips carefully and
always remember them.
A. If your front glass is blurry from the inside, it is caused by humidity. Follow these steps to clear it in seconds:
- The Climate Control Settings: Turn on the AC (it acts as a dehumidifier) and set the air source to Fresh/External Air, not re circulation. Turn the temperature to Heat and the fan speed to the highest setting while directing the airflow toward the windshield defroster vent.
- The “Salt Bag” Hack: Place a cotton bag filled with roughly 1 kg of coarse salt on your dashboard; the salt naturally absorbs moisture to prevent fog from forming.
- Silica Gel Packs: Keeping silica gel bags (like those found in shoe boxes) on the dashboard can also help keep the air dry.
B. External Protection (Rain & Snow Buildup)
To prevent rain droplets and snow from sticking to the outside of your windshield and side mirrors:
- Hydrophobic Coatings: Apply a water repellent like Rain-X or Glaco Mirror Coat Zero. These create a slick surface that causes water to bead and slide off instantly.
- Anti-Fog Films: You can buy inexpensive, transparent Nano-coating films specifically for side mirrors that prevent water and fog from adhering to the glass.
- Household Hacks:
- Shaving Cream: Rub a thin layer of non-gel shaving cream on the mirror and buff it off with a dry microfiber cloth to leave a temporary fog-resistant film.
- Toothpaste: Wiping a small amount of toothpaste over the mirror and then cleaning it off can also help prevent misting.
- The Potato Trick: Rubbing a cut potato on the glass leaves a starchy residue that acts as a natural water repellent.
C. Advanced Features
- Heated Mirrors: Many modern 2025 models (like the Nissan Rogue or Ford F-150) include heated side mirrors. These are often activated automatically when you turn on your rear window defroster.
- Rain Visors: Installing small “eyebrow” visors on your side mirrors can physically block light rain from hitting the glass.
Extra tips.
1: Always make sure you have tire chains whenever you go out of town/city in winter season.
2: Make sure you have a portable battery charger with you.
3: Remember to check your tire pressures before driving so far from the city.
4: If you are going for a long drive with your family, always have some rain coats plus warm clothes, especially
In Pakistan, India, Indonesia, Thailand, and some other countries, the weather is not predictable.
