3.Improper use of air conditioner: 67% of car owners mistakenly use internal circulation to aggravate fogging.

|---|---|---|---|
| Air conditioning cold air + external circulation | 8-12 seconds | 15-20 minutes | Emergency in summer |

3.Models without heated rearview mirrors: External waterproof film can be attached (waterproof rate increased by 60%)
5. Sharing of actual test experience from car owners
According to the actual measured data of Douyin’s popular videos:
• The air conditioning temperature is 26°C + the wind direction is adjusted to the windshield, and the defogging efficiency is increased by 35%
• Open the external circulation simultaneously when turning on the AC, which can shorten the recurrence time of fogging to 1.5 times
• After applying the anti-fog agent, let it sit for 3 minutes before wiping it off. The effect will be extended to 7 days.
6. Long-term preventive measures
1. Replace the air conditioning filter element regularly (recommended every 10,000 kilometers)
2. Place a dehumidification box in the car (the average daily water absorption is about 50ml)
3. The front windshield is hydrophobically coated (the anti-fog effect lasts for 6 months)
7. Safety reminder
• Never wipe the mist with your hands while driving (the risk of accidents increases by 300%)
• When fogging is severe, pull over immediately and deal with the problem.
• Disable wipers when rear window is fogged (may damage heating wire)
Through the above structured solutions, combined with practical tips that have been hotly discussed on the Internet recently, I believe it can help you effectively deal with the problem of car window fogging when driving in rainy days.
