How to Deal with Fogging on the Inside of the Windshield in Summer?
3 Answers
Methods to handle fogging on the windshield in summer: 1. The simplest way to deal with window fogging is to turn on the defrost setting on the air conditioning control panel. Activating this function will blow cold air from the vents below the windshield to clear the fog. 2. You can also open the car windows to lower the interior temperature and clear the fog, although this method takes longer and is less effective than using the defrost setting. 3. For fogging on the rear window, you can press the rear defrost button on the air conditioning control panel. Additionally, you can purchase an anti-fog spray for car windshields and apply it to prevent fogging.
When the windshield fogs up in summer while driving, I immediately turn the air conditioning to maximum fan speed directed at the glass, set to cold air mode, as this quickly absorbs moisture and removes fog, helping to restore visibility. At the same time, I slightly open the window to allow fresh air circulation, balancing the temperature and humidity differences inside and outside. For long-term fog prevention, I make it a habit to clean the windshield once a week with household soapy water or professional anti-fog agents, preventing dirt buildup to reduce condensation. If severe fogging occurs while driving, I promptly turn on the hazard lights and pull over to check, ensuring safety; avoid keeping damp items like umbrellas or wet towels in the car, as keeping the interior dry can prevent recurring issues. Remember, the air conditioning system should operate normally, with the temperature knob set to an appropriate level, not too low to waste energy.
To prevent windshield fogging in summer, I first clean the glass with soapy water before setting off, which helps form an anti-fog layer. Upon entering the car, I open the windows for a few minutes to let fresh air in and reduce interior humidity. Using the air conditioning in external circulation mode aids in expelling moisture, enhancing defogging effectiveness. Keeping the car interior clean and avoiding piling wet clothes or rain gear inside is essential. With high humidity and frequent rain in summer, I find it crucial to adjust the air conditioning temperature wisely—avoid setting it too low for comfort and instead use warm air or the defog button along with ventilation. For safe driving, I also check if the wipers are functioning properly and remove debris outside the glass to prevent combined interior and exterior fogging. Regular maintenance of the vehicle's air conditioning system ensures fuel efficiency and optimal performance.
