If there is fog on the front door glass that affects the rear-view mirror, you can adjust the direction of the left and right air outlets, blow against the left and right front door glass for a while, and wait for the condensed water vapor above to evaporate.

Method 3: air conditioning warm air demisting

The advantages of air conditioning and warm air demisting are obvious. Compared with the former two, the effect of this method will be more lasting and will not be repeated. The disadvantage is that the effect is relatively slow, and this method cannot be used for demisting during driving, that is to say, it needs to be blown in the cold air for more than ten minutes first.

Method four: spray mist removal.

The advantage of this method is that the effect will be better, and the maintenance time will be longer. Spray the defogger once in the glass, the effect will last about 5-10 days; however, the cost will be higher, and the defogger has chemical substances, without proper air exchange, it will have a certain impact on the air in the car and the health of people.
