Sterilization can usually be achieved through two methods: ozone disinfection and photocatalytic sterilization. Turn the car's heater to the maximum setting and cycle through all air vent modes, blowing for about 15 minutes. If there is an odor, use a deodorizer spray in the trunk.

A moldy trunk is quite common, usually caused by high humidity or water leakage. The first step is to empty everything and use a fan or dehumidifier to dry the trunk thoroughly, waiting at least half a day for complete dryness. For cleaning, I recommend a 1:1 solution of white vinegar and water—dip a soft cloth and gently wipe the mold spots; vinegar disinfects without damaging materials. Then rinse with clean water and let it air-dry. Don’t forget to check the trunk seal and car body for leaks—repair any issues promptly. For prevention, keep bamboo charcoal packs or silica gel desiccants inside to absorb moisture, and avoid placing wet items in the trunk during rainy days to prevent recurrence. Mold isn’t just smelly—it can also trigger respiratory problems, so address it early.

As someone who often works on cars myself, I've dealt with trunk mold several times. As soon as mold is spotted, immediately remove all items and vacuum up loose mold dust. Then mix baking soda with a bit of water to form a paste, apply it to the moldy area, wait 10 minutes, and gently brush it off—safe and cost-effective. Avoid using bleach as it can corrode plastic or fabric. After cleaning, let it air dry for half a day; sun exposure is even better. Before putting items back, toss in a few activated charcoal bags to absorb moisture and odors. Regularly check if the trunk's bottom drainage holes are clogged to prevent water accumulation. A simple DIY can handle it, saving you a trip to the shop and unnecessary expenses.

To deal with mold in the trunk in an eco-friendly way, I usually use diluted lemon juice or tea tree essential oil to wipe off mold stains. These natural substances are harmless and won't pollute the air inside the car. First, sweep away surface mold debris, then spray the solution and let it sit for a few minutes before gently scrubbing. Avoid excessive water to prevent moisture damage to the interior. After cleaning, ventilate and let in sunlight for a few hours, or use a fan to dry thoroughly. For long-term prevention, place cloth-wrapped rice or coffee grounds in corners to absorb moisture—eco-friendly and practical. Mold may harbor bacteria, so prompt cleaning is safer for health.

Safety first, a moldy trunk poses health risks, so I take action as soon as I smell it. Wear gloves and a mask during cleaning to prevent inhaling mold spores. First, use a damp cloth to wipe away visible mold stains, then spray with a professional automotive mold remover, following the instructions—test a small area first to ensure it doesn’t damage the material. Keep the trunk door open for ventilation to avoid chemical residue. After drying, place an electronic dehumidifier or regularly check the vehicle’s seals. For severe mold, it’s recommended to seek professional service to avoid allergic reactions from DIY mishandling. Regular maintenance of the trunk’s waterproofing is even more crucial.

Money-saving tips for dealing with trunk mold: I often use household items like hydrogen peroxide or vinegar—just pour a bit on the mold spots and scrub, which is low-cost and effective. Emptying the trunk and drying it quickly is essential; using a hairdryer to speed up drying is cheaper than buying equipment. After cleaning, stuff some old newspapers or dry rice bags inside to absorb moisture—economical and practical. The key is prevention: check for water leaks after car washes, and avoid storing wet items on rainy days. This saves money and hassle while preventing mold from affecting the car's interior and resale value.
