How to Deal with Minor Water Leakage in the Car?

If the water leakage is not severe, simply open the windows on a sunny day to allow thorough airing; Turn on the air conditioning and adjust the vehicle's circulation switch to internal circulation, enabling the water vapor inside the cabin to be expelled through the air conditioning system.

I remember driving through a heavy rain last autumn, and some water got into the car. The first step is to quickly lift the carpet and dry the steel panel underneath to prevent rust. Using dry towels to repeatedly press and absorb the water is the most effective method—don’t let moisture accumulate. Then, open all the car doors to allow natural airflow and park in a sunny spot for half a day to air it out. Remember to flip the floor mats to dry both sides, and use a small towel to soak up any water droplets in the seat seams. Water accumulation in the trunk corners is easily overlooked, so inspect those areas carefully. When parking, always remember to close the windows tightly, especially under trees, and regularly clean the drainage holes. Placing a few packs of activated charcoal in the car can help prevent musty odors—keeping the interior dry is crucial.

I've dealt with water ingress in cars several times and found that quick action is crucial. First, use a dry cloth to absorb visible water stains, and a vacuum cleaner is most efficient for under the carpets and seats. Opening all windows and doors for ventilation is essential; on rainy days, turning on the AC's cold air can help dehumidify. Check if the sealing strips have aged or hardened, causing leaks, and spray some rubber protectant to soften them if necessary. Pay attention to the circuits in the dashboard and door panels, using a hairdryer on low heat to dry the seams. Once, I forgot to clean the spare tire well in the trunk, leading to stagnant water and persistent odors. Remember to keep a dehumidifier box in the car and replace the activated charcoal bags regularly during the rainy season for peace of mind.

When water gets into the car, I immediately use a microfiber towel to press and absorb the water, which works better than an ordinary towel. While opening the windows for ventilation, I start the engine and turn on the external circulation, using the air conditioning to expel the moisture. Pay special attention to removing water from the floor mats and under the door sills, as mold there is the hardest to clean. On sunny days, take out the spare tire to dry it, as accumulated water in the spare tire well is a source of odors. Always keep car dehumidifier bags under the seats and replace them every half month during the rainy season. Identifying the source of the leak is more important—check if there are gaps in the windshield rubber seals. Clear the drainage holes yourself by poking them open with a wire to prevent water accumulation.
