In short, we will provide a detailed step-by-step solution to remove mold from carpets, upholstery and confined areas of the car.
Why does mold grow in cars?
Before looking for ways to remove mold from cars, it is equally important to know where it comes from. Quantitative measurements of environmental factors such as temperature and humidity define the normal growth of mold.
Common sources of mould in cars include:
- Water leaking from seals around doors, windows or the sunroof.
- Water pooling or stagnating inside the vehicle.
- Spilled drinks or wet items such as umbrellas and clothing.
- High humidity levels.
- Ventilation becomes poor when the car is parked for a long time
Understanding these causes can help remove the source and prevent further mold growth.
Mold infestation in cars and why it can be harmful
Mold can affect car owners in many ways. Besides being an eyesore, it also poses a serious threat; mold can have deadly consequences. Mold spores in a confined area such as the inside of a car can cause:
- Allergy symptoms (sneezing, coughing, watery eyes)
- Difficulty breathing.
- Coughing, accompanied by headache and fatigue.
- Worsening of asthma or bronchitis
If any of these symptoms appear while driving, a deep cleaning of mold in the vehicle is required.
Signs that you need to clean mold from a car
Many times, mold will not be visible, but that doesn’t mean it isn’t present. Below are some signs that your vehicle may need servicing:
- No odors while driving that bother you
- Damp or foggy windows even when it’s not raining
- Visible lesions on the headset, seat covers or carpet.
- Passion tends to increase allergy-related problems when traveling.
If this is the case, it’s time to carefully remove mold from the vehicle.
How to Remove Mold from Car Interior: A Comprehensive DIY Approach
Once you have confirmed the presence of mold in your car, there is no need to panic, follow these steps for mold removal and cleaning for your car interior.
Step 1: Gather Everything
For this specific task, you will need the following:
- Soft brush or sponge
- Spray bottle
- Microfiber towels
- Baking soda
- Dish soap
- Car mold disinfectant spray
- Enzymes
- Gloves and an N95 mask
- Vacuum cleaner with built-in HEPA filter
- Steam cleaner (optional)
Step 2: Ventilate the car
To begin with, it is important to open every window and door to allow air circulation in the car. Careful air circulation is of utmost importance as mold spores have the ability to spread into the air when they are shaken up.
Step 3: Remove personal belongings and clean wet surface
Remove all personal belongings, floor mats and any other wet items. Remove moisture using a wet/dry vacuum or towels.
Whenever possible, allow everything to dry completely in the sun, as UV rays are a natural fungicide.
Step 4: Vacuum the mold damage area
Remove mold spores from carpet, upholstery and other surfaces using a HEPA-filter vacuum. Please do not use a regular vacuum as it will release the spores back into the air.
Make sure you check the following:
- Underneath the seats
- Seat creases
- Floor mats
- Trunk carpet
Step 5: Apply a vinegar solution or enzyme cleaner
Choose one of the following to clean mold from car upholstery and surfaces.
Option A: Vinegar and water solution
- In a spray bottle, mix equal parts of water and white vinegar.
- Vinegar removes up to 82% of mold species, so be sure to spray liberally on the affected areas and let it sit for 15 minutes.
Option B: Enzyme-based mold cleaner
- These cleaners are designed for auto interiors and will penetrate porous surfaces.
- Always follow the manufacturer’s instructions for best results.
Never use bleach, especially on fabric, as it will discolor and damage the fabric.
Step 6: Scrape and Wipe
Use a soft cloth or sponge to gently scrub the areas where the mold is present. Then wipe with a damp microfiber towel. If necessary, repeat the steps until the mold is gone.
Step 7: Remove odors with baking soda
Often odors remain even after you’ve removed the mold.
- Sprinkle baking soda on the carpet and seats.
- Let it sit overnight; this allows the baking soda to absorb moisture and odors.
- The next day, vacuum up all the baking soda.
Step 8: Optional – Clean with a steam cleaner
Deep cleaning is best achieved when using steam; it can be used to:
- Eliminate existing bacteria, car germs and mold spores
- Remove mold dirt
- Clean fabric and leather
Avoid saturating surfaces with steam to maintain their integrity.
Step 9: Clean the HVAC system
If the AC is exposed to moisture, mold can grow in the vent areas.
- Replace the cabin air filter
- Set the AC to maximum temperature for 15 to 20 minutes
- Pour intake disinfectant HVAC spray into the vents
This prevents spores from circulating every time the air is turned on.
How to get rid of mold in a car permanently
After completing the cleaning, preventing the mold from returning is the next and final step. Here is how to ensure that the mold does not return:
- Check and fix leaks immediately: Keep an eye on windows, seals, and doors for leaks.
- Use moisture removal products: In high humidity areas, moisture removal products and silica gel pouches are very effective.
- Regular ventilation: Open the windows and sunroof when the vehicle is parked in the garage.
- Remove damp items: Towels, umbrellas, gym bags, and clothes should not be wet, and hence need to be removed.
- Clean up spills immediately: A cup of coffee or soda spilled invites mold very quickly. So be sure to remove coffee stains and clean up soda spills immediately.
- Vacuuming on a regular basis: Removes dirt and organic debris from inside the automobile.
When to Seek Professional Car Mold Treatment
If mold reappears, it may be time to hire a professional or car detailer. DIY works, but not always.
Their arsenal includes:
- Ozone treatments
- Industrial steamers
- Commercial-grade enzyme treatments
DIY practices usually skip areas behind door panels, headliners, and dashboards, so professionals check those areas first.
