Safe Driving in the Rains

 Windscreen / Window fogging:

• Remember the fundamentals : Window fogging occurs due to a temperature difference between the inside surface of your glass and the outside. For example, if you drive without the air-con and all your windows are shut, the cabin is warmer than the outside, resulting in the window fogging up from inside. On the other hand, if you run your air-con on full blast mode, the interiors of your car will be colder than the outside. Thus, your glasses will fog up from the outside. 
• Keep the air-con on fresh air / ventilation mode. 
• It is important to maintain the right temperature balance between the inner & exterior sides of glass. Don't turn your air-con to full blast. Keep it at a level which is just about comfortable.
• Use your rear windscreen demister liberally. It heats up little wires in your rear glass and gets rid of the mist / fog.
• When the windows fog from the inside, the best thing to do is to switch the aircon on. It will clear up the screens in a jiffy. The situation is a little tricker when the windows fog up from the outside. The ideal solution is to roll down the windows a little, and let the air flow more or less neutralize the temperature difference. Most modern cars come with the demist / defog mode as part of the standard HVAC system.

Drive safe! The rains are simply beautiful. Taking the necessary precautions will make your rainy drives a pleasure that you will look forward to!
