What Type of Air to Use for Defogging the Car in Summer?

[AdrianaAnn]

Actually, whether you use warm or cold air, both can effectively defog the car, but they work on different principles. Here are the key differences: 1. Cold Air Defogging: The advantage of this method is its speed. It quickly balances the temperature inside and outside the car near the windows, acting like an invisible barrier between the heat and moisture from passengers and the glass, preventing contact. Remember to switch the air conditioning to external circulation mode. The downside is that it can get quite cold, and you need to keep the cold air on to maintain the effect. 2. Warm Air Defogging: This method is more sustainable. It works by increasing the temperature to evaporate the fog droplets, essentially 'heating' the car glass. However, this approach can be initially frustrating as it may temporarily increase fogging inside the car. Additionally, this method is ineffective when the car has just started and the engine hasn't warmed up yet.
