Cleaning method for car air conditioning vents: Turn off the air conditioning cooling function, select the natural ventilation mode, and spray professional air conditioning cleaner into the air ducts through the car's air conditioning vents. After spraying the cleaner, let the air conditioning run in external circulation mode for 10 minutes to allow the cleaner to fully take effect. The cleaner will then flow out through the car's drainage outlet. Do not turn off the air conditioning at this point; continue running it until the air ducts are completely dry, indicating the cleaning process is complete. Below is related information: 1. Car air conditioning is used to adjust and control the temperature, humidity, air cleanliness, and airflow within the car cabin to optimal conditions, providing passengers with a comfortable environment, reducing travel fatigue, and creating favorable working conditions for the driver.

Cleaning car air vents is actually quite simple. As someone who enjoys DIY, I often do it this way: First, turn off the engine for safety, then carefully remove the vent covers (some can be pulled off directly). Prepare a small brush or an old toothbrush to gently remove surface dust, and use a small car vacuum cleaner to suck out the accumulated dust inside. If there's a strong odor, spray some car-specific interior cleaner on a soft cloth and wipe the vents—avoid using too much water to prevent leakage into the control panel. After cleaning, reassemble and test the vents; the air will be fresher, and you'll save on repair costs. Doing this every three months helps maintain the AC's efficiency, reduces bacterial growth, and benefits respiratory health in the car, preventing allergies or colds. Remember to wear gloves for protection—safety first.
