What to Do When the Windshield Fogs Up?

[DianaLynn]

To deal with a foggy windshield, you can turn on the car's heating system and direct the warm air towards the glass to reduce the temperature difference between the inside and outside surfaces, thereby preventing condensation and fogging. Many vehicles are equipped with a defogging function—simply lower the air conditioning temperature and activate the defogging feature. Alternatively, you can use a defogging spray by applying it to the windshield to effectively reduce fogging. Fogging occurs due to the temperature difference between the inside and outside of the car, so adjusting the air conditioning to minimize this difference can help remove the fog. Manual air conditioning systems do not have a one-touch defogging feature and require manual adjustment to complete the defogging process. After defogging, adjust the temperature appropriately; avoid setting it too low immediately to prevent fogging from recurring. Once the windshield temperature matches the interior temperature, fogging will no longer occur.
