Discover How to Use Toothpaste and Neutral Detergent to Improve Your Visibility While Driving in the Rain
On heavy rain days, drivers often face the problem of fogged mirrors and windshields or covered with droplets of water. Fortunately, a simple and affordable trick can help to improve visibility during these times, according to the website Diario do Litoral.
How to Use Toothpaste on the Mirrors
To prevent the mirrors from fogging or becoming covered with droplets of water, follow these simple steps:
- Cleaning the Mirrors: Use a clean, dry cloth to wipe the surface of the mirror.
- Applying the Toothpaste: Apply a small amount of toothpaste without abrasive crystals (such as those found in whitening pastes).
- Spreading: Spread the product until the surface becomes clear.
- Result: The toothpaste creates a thin protective layer that helps to repel water, improving visibility.
Why Does It Work?
The toothpaste contains detergents that reduce the surface tension of water. This causes the droplets to run off the mirror instead of accumulating, providing greater safety while driving in the rain.

Important Considerations
- Avoid toothpaste with abrasive crystals to avoid scratching the mirror.
- The layer of toothpaste should be thin to avoid distorting the reflection.
- After use, clean the mirror when the vehicle is in a dry, covered location.
- Always test the visibility of the mirror before driving in rainy conditions.
How to Prevent the Windshield from Fogging
For the windshield, the solution is a bit different. To prevent the inside of the windshield from fogging, follow the steps below:
- Applying Neutral Detergent: Place a small amount of neutral detergent on the inside of the windshield.
- Spreading: Use the soft part of the sponge (yellow) to spread the product.
- Drying: Wait for the detergent to dry. Even if the glass looks slightly whitish during the process, this effect disappears after it dries.
