How to Deal with Severe Musty Smell Caused by Water Accumulation in the Car?

The most effective way to release harmful gases is through ventilation, although this method is also time-consuming. Among the methods to mask odors, placing some strongly scented fruits in the car can help their fragrance disperse over a long period. Car owners can purchase products that absorb odors and freshen the air, placing them in the car regularly to maintain fresh air at all times.

My car had the same issue a couple of days ago—after the rain, the passenger side floor mat was soaked and even grew mold. First, remove all the floor mats to rinse and air-dry them. Use towels to soak up any water under the seats, then dry the carpet thoroughly with a high-power blow dryer. The key is to locate the water entry point: the most common cause is clogged sunroof drainage holes—use a wire to clear the drain pipes. Aging door seals can also leak. Afterward, place activated charcoal bags inside to absorb moisture. If the mildew smell is too strong, use an automotive-specific mold-removal spray on the affected areas and leave the windows open for two days of direct sunlight—that should do the trick. Avoid parking under trees regularly, as fallen leaves can easily block drainage holes.
