Rain can quickly cover a car’s side mirrors with water droplets, making it harder to see what’s happening alongside the vehicle. That’s why many drivers look for products that can help keep their mirrors clear. There’s also a simple home remedy that may help repel water from the glass.

How to Protect Your Car Mirrors From Rain

Before applying anything to the mirror, the surface needs to be prepared. Start by completely drying the mirror, then apply a small amount of toothpaste to the glass.

If you’ve ever struggled to see anything in your side mirrors while driving in the rain, this simple trick may be worth trying. All you need is basic toothpaste and a microfiber cloth.

Rub the toothpaste thoroughly over the mirror’s surface using the microfiber cloth. Make sure the entire area is evenly covered.

Once the mirror has been treated, test the result with some water. Instead of remaining on the glass as droplets, the water should run off the area where the toothpaste was applied.

The method is simple and doesn’t require any specialized automotive products.
