Why Do Car Windows Fog Up During Intimate Activities?

[IsabelFitz]

Window fogging occurs due to significant temperature differences between the interior and exterior of the vehicle. Solutions to prevent fogging are as follows: 1. Utilize the air conditioning system. While driving, first turn on the cooling function; for a thorough solution, it's best to activate the heating function either before driving or when parked roadside until all condensation disappears. 2. Create cross-ventilation by opening windows. Understanding the principle of fog formation, you can avoid using AC altogether by slightly lowering both side windows to establish air convection. This method equalizes interior and exterior temperatures. 3. Purchase specialized anti-fog products. Apply anti-fog spray evenly on the inner surface of the windshield. The market also offers anti-fog cloths in dry and wet variants, which provide quicker but shorter-lasting protection (typically under 24 hours). 4. Household remedies using dish soap or soapy water. Applying diluted dishwashing liquid or soap solution to the windshield can similarly create an anti-fog effect.
