Many drivers would love to know tricks on how to keep the car windshield from fogging up. It seems like it always happens at the worst possible time. While driving on the highway in a torrential downpour of rain or on a cold winter morning while commuting in to work. There is nothing more annoying than having to battle a fogged up windshield while trying to drive at the same time.
- Use the vehicle's front defroster. Most vehicles have front defrosters which use a combination of vents and a blower to heat and direct air towards the windshield. Always try to use the defroster before you need it in order to have the greatest quality of visibility for the longest amount of time.
- Use the vehicles rear defroster. If examined closely, most rear windows have horizontal lines through them. It may be interesting to note that they are electrical wires. When the rear defroster is turned on, the wires emit a small amount of heat in order to get rid of the compensation on the outside of the vehicle.
- Purchase a product. There are products on the market that are available to prevent windshields from fogging and also tout the ability to improve visibility. These products are normally rubbed into the windshield and help the rain or condensation to "roll off" vehicle windows. There are even some which claim to help reduce glare at night and last for up to six months after application.
Please be safe and pull over if windshields have low visibility due to rain or fog. It is always better to be safe and get to your destination late than to drive in unsafe conditions and run the risk of never arriving at all.
