How to Deal with Fog on the Windshield?
2 Answers
Methods to deal with fog on the windshield: 1. Use defogging spray to remove fog. Simply spray it evenly on the glass surface and wipe it clean with a dry towel; 2. Turn on the windshield wipers. Just set the wipers to the lowest setting and let them run until the fog disappears; 3. Change the air source. Most cars are equipped with buttons to circulate the air inside the car or draw in air from outside; 4. Lower the temperature inside the car. Since fog is caused by temperature differences, matching the interior temperature with the outside temperature can reduce fog. Set the car fan to the highest setting and lower the temperature as much as possible.
Foggy windshields are very annoying. I've encountered this countless times in over a decade of driving. The key to handling it is controlling temperature and humidity. I usually press the defogger button immediately - most cars have one, which can quickly activate the air conditioning system. Turning on cold air works fastest; increase the fan speed and direct the vents at the glass, and the fog will clear in seconds. In cold winter weather, warm air also works but takes slightly longer. Simultaneously turn on the external air circulation to introduce fresh air and reduce moisture buildup inside. Dirty glass fogs up more easily, so I regularly clean it with special anti-fog solutions for good preventive results. If sudden fogging obstructs my view while driving, I always find a safe place to stop first before dealing with it, as impaired visibility easily leads to accidents. Developing this habit has made driving much safer.
