How to Remove Water Droplets from Car Glass in Rain

[JamesRose]

First, clean off any dirt and sand attached to the glass to prevent scratching during subsequent wiping. Take a bar of soap, add some water to soften it, and fully dissolve the soap to create soapy water (a simple glass cleaner). Soak a cotton pad or soft towel in the soapy water, then evenly apply it to the glass. Wait until the soapy water dries, and it will turn into a powdery residue on the glass. Gently wipe it off, and rainwater droplets will be less likely to stay on the glass.
