Rice, the Moisture Trapper
You’re probably heard that rice is a great moisture absorbent. Most people use bowls of uncooked rice to suck the moisture out of smartphones that they dropped in toilets or sinks. However, if your car suffers from a case an abundance of too much moisture, a bowl of rice could be exactly what you need.
All you need is a a cloth bag that’s chock-full of rice. Make sure the mag is porous enough for air to pass through while also retaining the rice grains. A cheesecloth is a great option. Anyway, the rice bag will soak up any moisture in the air, keeping your windshield free of condensation for longer.
