How to Prevent Mold When Not Driving for a Long Time?

Keep the car body clean and dry before parking. Carefully check areas prone to water accumulation at the bottom of the car, and remove any accumulated water promptly. Perform maintenance on the car before parking, including changing the oil and three filters. Then disconnect the positive and negative terminals of the battery to prevent it from losing charge. If parking outdoors, always park the car in a relatively elevated location. If it rains, the car could easily become waterlogged. Make sure to park the car on a fairly level surface. Parking on a level surface ensures even stress distribution on all suspensions.
To prevent mold when not driving for a long time, I think the best approach is to tackle the humidity issue first. I usually park my car in a well-ventilated area, such as an open-air parking lot or garage, avoiding damp underground spots. Interior cleanliness is crucial—I wipe down the seats and carpets with a damp cloth to remove debris and stains, then spray some antibacterial spray after they dry. If the car will be parked for over a month, I place moisture absorbers inside, like bamboo charcoal bags or silica gel packets, which are affordable, eco-friendly, and effective at absorbing moisture. Regularly starting the engine is also essential—I make a habit of driving it for about ten minutes every two to three weeks, turning the AC to maximum airflow for a few minutes to remove dampness from the vents. This prevents mold growth and avoids musty odors. Choosing the right parking spot is key too—I try to park where sunlight can reach the car, letting the interior air-dry naturally to keep it dry and fresh.
From a technical perspective, the key to preventing mold is controlling humidity inside the car. I've noticed the air conditioning system is most prone to issues, so I always clean the AC filter before long-term parking to avoid dust accumulation and mold growth. When parking, I leave a small window gap for ventilation to promote air circulation - simple yet effective. For moisture absorption products, I recommend specialized automotive drying bags placed in the glove compartment and rear seats, which can continuously dehumidify for several weeks. Don't forget to inspect roof and door seal strips - replace any aging or leaking ones promptly to minimize water ingress. After parking, I make it a habit to open the trunk briefly to release accumulated moisture. Regular engine starts are crucial - running the engine for a few minutes activates the fan system to expel dampness from AC ducts, delivering remarkable anti-mold results.
