Car Interior Disinfection: Destroying Bacteria, Fungi and Mold with Dry Fog
Dry fog disinfects a car interior at the molecular level — reaching the vents, A/C evaporator and fabrics to destroy bacteria, fungi and mold at the source.
Car interior disinfection with dry fog destroys bacteria, fungi and mold throughout the cabin — not just on the surfaces you can wipe. A glycol-based liquid is atomized into a dry fog of 5–20 micron particles that behave like a gas, filling the whole interior and reaching the vents, the air-conditioning evaporator and deep into the fabric where germs and odors actually live. The carrier then evaporates without leaving moisture, streaks or residue.
Why is a car interior so unhygienic?
A car cabin is a warm, enclosed space that we touch constantly. Microbes accumulate in places a cloth never reaches:
- the air-conditioning evaporator, where condensation feeds mold and bacteria
- ventilation ducts and dashboard vents
- seat fabric, carpets and the headliner
- seat belts, the steering wheel and other touch points
Wiping the visible surfaces leaves most of this untouched — which is why smells and allergies keep coming back.
How does dry fog disinfect the whole cabin?
Because the fog behaves like a gas, it goes everywhere the air goes. An antibacterial / disinfectant solution rides on those microscopic droplets and settles on every surface, including the inside of the ventilation system, where it destroys the organisms that cause odors and illness.
| Dry fog destroys | Where it hides | Result |
|---|---|---|
| Bacteria | Fabric, touch points, vents | A hygienically clean cabin |
| Fungi & mold | A/C evaporator, damp carpets | No musty or mold smell |
| Odor-causing microbes | Headliner, seats | Lasting freshness |
A single treatment can destroy up to 99% of bacteria on treated surfaces.
Does it remove mold and the "air-conditioning smell"?
Yes — and this is where dry fog matters most. The sour A/C smell comes from mold and bacteria growing on the damp evaporator deep inside the dashboard, which you cannot reach by hand. With the A/C running on recirculation, the dry fog is drawn through the ventilation system and disinfects the evaporator at the source.
Is the disinfectant safe and certified?
In the EU, interior disinfectants are biocidal products regulated under the Biocidal Products Regulation (BPR, EU 528/2012, Product-Type 2). CarFog OÜ supplies certified, EU-compliant liquids that leave no toxic residue and evaporate cleanly. No one stays inside during treatment, and after a short airing the cabin is safe to use.
Who needs car interior disinfection?
- Car washes and detailing studios — a high-margin add-on service
- Used-car dealers — a fresh, hygienic cabin sells faster
- Taxi, rental and car-sharing fleets — protection between customers
- Families with children or pets — regular, residue-free hygiene
How long does a treatment take?
About 45–60 seconds of fogging, then the cabin stays sealed for 15–20 minutes while the fog works, followed by a short airing. No drying time, no wiping and no streaks.
CarFog OÜ supplies the equipment, certified liquids and support for car-interior disinfection across Estonia — for single cars, detailing studios and self-service installations alike.
