How to Deal with Mold in the Trunk?

Before parking, turn on the warm air mode of the air conditioner to dry out the moisture in the air conditioning ducts and the interior of the car, preventing the car environment from becoming too humid and causing mold. Place some activated bamboo charcoal in the car to absorb moisture and harmful substances, thereby regulating the humidity inside the car. Install a solar-powered air purifier or place a car air purifier in the vehicle to absorb dust and impurities in the air, preventing mold from forming inside the car.
Last time my car trunk also got moldy, which was quite troublesome. I first used a vacuum cleaner to suck up the mold residue, then wiped the mold stains with white vinegar mixed with water. For areas with heavy mold odor, I applied alcohol cotton pads for a few extra minutes. After drying, I also placed half a bag of activated charcoal to absorb moisture, and on rainy days, I put a dehumidifier box in the trunk. The most crucial step was discovering the leak point—the aging seal strip on the right taillight was causing water ingress. Replacing the seal strip finally solved the problem completely. After washing the car, don’t forget to leave the trunk open for half an hour to air out, especially under the trunk mat where moisture tends to accumulate the most.
Dealing with a moldy trunk requires different approaches based on the situation. Light mold stains can be wiped off with a towel dipped in baking soda water, while stubborn mold spots require chlorine-based bleach (ensure proper ventilation). After thorough cleaning, it's essential to keep the area dry—placing a few diatomite dehumidifying blocks works faster than activated charcoal. I use a hairdryer on the cool setting to blow air into the crevices for five minutes every week, especially around the spare tire well. If the carpet is severely moldy, replacement is the only option. Last time, I switched to an antibacterial-coated waterproof mat, and it has stayed mold-free even during the rainy season. Always check that the drainage holes aren’t blocked by leaves—standing water will inevitably lead to mold.
