Fungus is not only unpleasant to look at, but it can also leave behind a musty smell and damage the interiors. In some cases, it can even trigger allergies or respiratory issues. While most people don’t expect fungus to grow inside their cars, the warm, damp and poorly ventilated environment of a vehicle makes it an ideal breeding ground.
Since fungus spreads quickly through airborne spores, ignoring it can lead to major problems, including health risks and deeper damage to your car’s upholstery. The good news? With the right approach, you can effectively eliminate it.
This article discusses the common signs of fungal growth and the methods for removing it from your car.
Tips on how to clean fungus from car seats
Fungus in your car isn't just an eyesore; it can also be bad for your health, especially if you have asthma or allergies. Some common reasons for fungus growth are spills of liquid, high humidity or driving in damp places. Here’s how to clean fungus from a car seat:
1. White vinegar solution
- Mix white vinegar with water in an 8:2 ratio
- Put the fluid on the affected area using a clean cloth or a spray bottle
- Let it soak for 15 to 20 minutes
- Use a wet-dry vacuum to clean the area
- Keep doors open to ventilate and remove the vinegar smell
2. Baking soda treatment
- Mix 1/4 cup of baking soda with 200ml of water
- Apply the solution to affected areas
- Scrub gently with a brush
- Wipe clean and allow to dry thoroughly
- Vacuum the area to remove any residue
3. Clove oil method
- Create a 1% solution (1/4 teaspoon of oil in one litre of water)
- Apply carefully to the affected areas
- Let it sit longer for better results
- Repeat the process if necessary
- Allow 1-2 days for full drying
4. To keep fungus from returning
- Keep your car interior dry
- Fix any leaks quickly
- Use a dryer if necessary
- Avoid eating in the car to avoid spills
- Regular cleaning and upkeep
Signs your car seats are affected by fungus
Watch out for these common indicators that suggest fungal growth in your car:
- Earthy or musty odour
- Damp or clammy seat surfaces
- Discoloured spots or patches
- Irregular patterns or clusters on the upholstery
- Growth in hidden or shaded areas
- Foggy or hazy windows caused by excess moisture
- Allergic reactions such as sneezing, coughing or skin irritation
Natural remedies vs chemical cleaners: Which works better?
Choosing the right cleaning method is crucial for effectively removing fungus. Depending on your priorities, you can opt for either natural remedies or chemical cleaners.
Chemical cleaners typically offer faster and more reliable disinfection. They are highly effective against stubborn fungal growth but must be used with caution, ensuring proper ventilation and protective gear.
Natural solutions, on the other hand, are ideal for mild to moderate fungal issues. They’re non-toxic and safer for children, pets and sensitive individuals. However, remedies like vinegar or baking soda may require more time, repeated application and thorough rinsing to achieve the desired results.
How to prevent fungus from returning in your car
Once the fungus is removed, the key is to prevent it from returning. Keeping your car’s interior clean, dry and well-ventilated is your strongest defence. Use moisture absorbers like silica gel packs, vacuum the seats regularly and clean spills immediately to prevent dampness. Improve airflow by opening windows periodically, running the AC or heater to remove moisture and checking for leaks or water intrusion that could create a humid environment.
Professional cleaning vs DIY: What’s best for your vehicle?
Your choice depends largely on the extent of the fungal damage. DIY cleaning works well for mild cases and is preferable if you want to handle the process yourself using easily available products. It’s cost-effective and lets you clean at your own pace.
Professional cleaning, however, delivers deeper results and longer-lasting protection. Experts use specialised tools and treatments that can help maintain your car’s interior quality and even support better resale value.
Remember, the right option comes down to your budget, time availability and how much expert attention your car’s interior truly needs.
Importance of regular car maintenance and hygiene
The presence of fungus often signals deeper issues, highlighting why consistent upkeep is essential. With regular maintenance and proper hygiene, you can benefit in several ways, such as:
- Safety: A clean interior helps reduce health risks, while routine checks on seats, belts and other components keep your car safe to use.
- Performance: Regular servicing ensures all systems run smoothly, helping your car perform better and last longer.
- Cost savings: Tackling small issues early prevents them from turning into major, expensive repairs.
- Resale value: A well-maintained, hygienic car interior enhances the vehicle’s market value when you decide to sell it.
How car insurance can help cover interior damage
Fungal damage often occurs due to moisture and poor upkeep, but in certain situations, your insurance may help. With a comprehensive car insurance policy, interior repairs or cleaning may be covered only if the fungal growth is a direct result of an insured event, such as flooding, water ingress from an accident or other covered external incidents. Comprehensive coverage acts as a financial safety net against various risks, such as damage, accidents and theft.
Remember, third party insurance is mandatory, but it will only protect you against liabilities to others, not your own vehicle.
If you feel it’s time to better prepare for future unwanted expenses, reviewing your insurance plan can help. You can fill out the form on this page to receive personalised guidance and suitable insurance options.

3. How should I clean fungus on the seat belt webbing?
Gently pull out the full length of the seatbelt, secure it so it doesn’t retract and clean it. Allow it to air-dry completely before letting it retract and wiping it down with a soft cloth.

In some individuals, especially those with allergies or weakened immune systems, exposure to fungal spores can trigger symptoms such as vomiting, coughing or respiratory irritation.
