Causes of mold in car
Because the inside of a car is so small and the airflow is so restricted. Hence, any presence of mold in the AC system almost guarantees that you’ll get mold exposure in car.
Let’s discuss the root of the issue at hand. According to the Environmental Protection Agency (EPA), mold is, “a natural part of the environment and can be found almost anywhere that moisture and oxygen are present. They belong to the kingdom Fungi and live in moist places such as soil, plants and dead or decaying matter.”
So, it’s clear based on that description why mold would so commonly find its way into cars. The vehicles people use to transport from point A to point B, can harbor the mold spores and moisture you track in.
From twigs and dead leaves to the simple presence of excess water after a heavy rain. The contamination you bring into your car can stay, and even worse than that, it can grow.

There are several ways in which mold growing in car interior, such as:
- You keep the windows open during rainy weather;
- You park your car in a damp garage;
- Spilling liquids and juices on the floor and seats while driving
- Your family leave damp materials in the interior;
- Some water leaks from the roof or windows;
- Bad ventilation in the passenger compartment
Hence, in all of these situations, your car interior is subjected to excessive moisture. Microscopic mold spores will form first. And they will quickly spread to all parts of your interior.
This process will speed up if you blast the air conditioning system, as the circulating air helps spread any airborne mold spores throughout the cabin.

Proper ventilation parking
First of all, make sure you park your car in a good ventilation area. This will allow for adequate airflow while cleaning.
And you will have good lighting to check for mold in car, too.
Initial Cleaning
Remove all items from your car, including the floor mats, seat covers, and personal belongings.
Why?
This will make it easier to access moldy areas.
After removing all the items, use a vacuum cleaner to remove loose mold spores and prevent them from spreading further. Pay extra attention to carpets, seats, and crevices. Make sure that you cover all areas of the interior, including the seats, floor mats, doors, and the center console. Move the seats all the way backward and forward to remove all the debris beneath them.
And, don’t forget to vacuum inside the cup holders as well.
Carpet mold in car
We recommend you clean carpet mold outside the vehicle.
Mold spores are heat-sensitive and can be destroyed at high temperatures. Steam water typically reaches a temperature of 100° C. And this is sufficient to kill most types of mold.
However, it’s important to note that while boiling can kill active mold growth, it may not completely eliminate mold spores or mycotoxins that are already present. Therefore, you will need commercial cleaning products later.
Vapor steam cleaners can instantly eliminate dust mites and mold spores. And they can also dissolve grease, grime, buildup, and tough stains. If the steamer comes with a brush on the end, you can have a bit of scrubbing. Make sure all carpets are completely dry before you put back to your car.

Vapor steam cleaners use dry steam. It contains only about 6 percent more moisture than the air we breathe. This means that vapor steam cleaning won’t oversaturate carpets and upholstery. And the moisture starts to evaporate almost immediately on the surface. These machines can produce thousands of gallons of steam per hour using just a small amount of water.
Commercial mold cleaning products are designed to target and eliminate mold effectively. These products often contain powerful chemicals that penetrate deep into surfaces to kill mold spores. And you can mix it with parts water in a spray bottle and liberally spray on the affected area. After letting it sit for a couple of minutes, scrub the area with a brush.
Tips
- Mix a few drops of hydrogen peroxide with water in a steam cleaner. Because hydrogen peroxide can kill mold in car by breaking down their essential components like their proteins and DNA quickly. We recommend 3% as a standard for cleaning mold.
Drying out
After cleaning, it’s essential to dry the area thoroughly. Use a wet-dry vacuum to extract any residual moisture. Following this, keep the car doors and windows open, allowing direct sunlight to further aid in drying. And leave an exhaust fan on for a few hours to dry the carpet floor.
Remember, moisture is mold’s best friend; depriving it of this means preventing its return.
