Here are the solutions for when the car sunroof was left open and rainwater gets inside: 1. Clean the interior items: Items in the car can easily get moldy when damp. Remove and wash detachable items like floor mats and seat covers, then dry them thoroughly in the sun. Carpets can be directly treated with a vacuum cleaner. If necessary, use a specialized detergent for cleaning, but ensure the carpet is completely dry after washing. 2. Disinfect: For seat covers and seats, it's best to rinse them with bleach to prevent bacterial growth. The evaporator box and blower of the air conditioning system should also be removed and disinfected. An air purifier can be used to eliminate odors inside the car.

I've experienced this situation before when I forgot to close the sunroof and a heavy rainstorm caused water to enter the car. The first reaction is crucial: quickly use towels or rags from the car to soak up the water on the seats and floor, preventing it from seeping deeper. Then, open all the doors and use a fan or turn the air conditioning to maximum speed for several hours to let the moisture evaporate. Wet carpets, if not treated promptly, can grow mold, develop a foul smell, and even cause rust on the car frame. The next day, it's best to check the sunroof tracks to ensure there's no standing water. If the situation is severe, it's advisable to drive to a repair shop to check the electrical safety. Developing a habit of checking the car when locking it can prevent such troubles—don't be careless like I was.

A sunroof left open causing water ingress can range from minor to serious, so handle it step by step without panic. First, use old cloths to soak up the water, focusing on the driver's seat and floor mats to prevent prolonged soaking from damaging wiring and upholstery. Then, ventilate the car by using a household fan to blow air over the wet areas for a day, or place several moisture-absorbing packets inside the vehicle. If significant water has entered, it may affect the dashboard and cause electronic malfunctions such as navigation failure, so it's advisable to visit a professional shop afterward for thorough drying and inspection of the seals. Remember to regularly clean the sunroof drainage holes to prevent blockages and water ingress, as these small maintenance tasks can save a lot on repair costs.
