REMOVE MILDEW SMELLS AND MUSTY SMELLS
Getting rid of mildew and musty smells in your car interior involves more than just masking the odor with an air freshener or baking soda. Mildew is often first smelled before it is seen, making early detection important. Since mildew is a living organism and air born bacterias, the key is to stop its growth. Here’s how you can do it:
Remove Visible Mold:
First, clear out any obvious sources of mold and mildew, like old food or damp clothes. If you have smelled a persistent musty odor, check hidden areas for mold. Visible mold needs to be physically removed. Use vacuum cleaner but make sure your true away filter after and clean your vacuum.
Use a Steam Cleaner:
Mold can’t survive in high heat. A steam cleaner, which doesn’t use chemicals, is great for killing both visible and hidden mold in your car. The steam reaches a temperature that’s high enough to stop mold growth.
Air Out Your Car:
On a sunny day, leave your car with the windows open to let it dry out completely. Sunlight and fresh air are natural enemies of mold. If it’s windy, that’s even better for airing out your car.
Use an enzyme cleaner
Is a cleaning solution that uses natural enzymes and sometimes good bacteria to break down stains and odors at a molecular level. Enzymes are proteins that act as catalysts, speeding up specific biochemical reactions.
In cleaning, these enzymes typically target organic substances like proteins, fats, and carbohydrates, which are common components of stains and odors. By eliminating the source of the odor, you can significantly improve the overall car smell.

Say Goodbye to Musty Odors
Keep your car fresh and clean with these simple steps!
Run the AC on a low setting with the car running and the windows down for 10-15 minutes during the cleaning process.
1. Identify the Source of Moisture
Start by locating the source of the smell. This could be wet carpets, damp seats, or hidden leaks. Inspect areas such as:
Under the seats.
Back seat, as moisture and odors often accumulate here.
Around the windows, window seals (check for leaks that could contribute to moisture buildup), and sunroof seals.
Inside the trunk.
2. Remove All Wet or Damp Materials
Take out any removable items, such as floor mats or seat covers, and allow them to dry thoroughly in the sun.
If a floor mat has absorbed odors, especially from cigarette smoke, clean or replace the floor mat to help eliminate persistent smells. Sunlight is a natural disinfectant that helps kill mold spores.
Place wet items in a large container to transport them for cleaning, or use a large container filled with odor-absorbing material in the car during the drying process.
3. Vacuum the Interior
Use a vacuum with a HEPA filter to clean the interior thoroughly. Pay special attention to:
Carpets and floor mats.
Seats and crevices.
Door cards.
Air vents and dashboard.
Vacuuming removes visible mold and dirt, preventing further spread.
4. Clean with White Vinegar Solution
White vinegar is a powerful mold killer. Here's how to use it:
Mix equal parts white vinegar and water in a spray bottle.
Spray the affected areas lightly.
Let it sit for 15-20 minutes.
Wipe with a clean microfiber cloth.
5. Baking Soda for Absorbing Odors
Sprinkle baking soda on the carpets and seats to absorb lingering smells. Leave it overnight, then vacuum it up the next day.
6. Use Specialized Cleaning Products
For stubborn mold or mildew, use commercial cleaning products designed for car interiors. Look for products containing enzymes or antifungal agents.
7. Treat Air Vents
Mold spores can lurk in your car’s air conditioning system. To clean:
Replace the cabin filter. Dirty filters or clogged cabin filters can contribute to musty odors and prevent optimal airflow, so be sure to check and replace them regularly. Both cabin filter and cabin filters should be maintained as part of routine HVAC care.
Clean the AC vents and plenum intake vent to remove mold and bacteria buildup that can cause unpleasant smells.
Use a disinfectant spray or specialized AC cleaner, which can be sourced from an auto parts store.
Check and clean the evaporator drain to ensure water does not collect inside the evaporator inside the heating and cooling system, as trapped moisture can lead to mold, bacteria, and a sweaty sock odor. If water sits long in the evaporator or AC system, it can promote bacterial and mold growth, resulting in musty smells.
Maintain the entire heating and cooling system, including the cooling system and evaporator inside, to prevent water collects and musty smells.
Run the AC on a low setting with the car running and the windows down for 10-15 minutes during the cleaning process.
8. Treating the Air Conditioner
Musty smells often linger in your car’s air conditioning system, making it essential to treat the air conditioner directly for effective odor removal.
Begin by turning on the car’s interior fan to a low setting and opening the windows to air out the car. This helps circulate fresh air and push out any trapped odors.
Next, locate the plenum intake vent—usually found near the base of the windshield.
With the air running, spray a disinfectant spray, such as Lysol or a specialized AC disinfectant from an auto parts store, directly into the plenum intake vent.
This process helps kill bacteria and mold that can cause musty odors within the air conditioning system.
Before spraying, remove the cabin filter to allow the disinfectant to move freely through the system.
If your cabin filter is dirty or clogged, replace it with a new one to restore optimal airflow and prevent future smells.
A clean cabin filter is crucial for keeping the air inside your car fresh and free from unpleasant odors.
After treating the system, let the air conditioner run for a few minutes with the windows open to ensure any remaining odors are expelled.
Regularly maintaining your air conditioning system and replacing the cabin filter will help prevent musty smells from returning and keep your car’s interior air clean and pleasant.
9. Killing Mold with Enzyme Cleaner
Enzyme cleaners are a powerful tool for eliminating musty smell and mold from your car upholstery and other interior surfaces.
These cleaners use natural enzymes to break down organic matter, effectively targeting the root cause of odors rather than just masking them.
To use an enzyme cleaner, first test it on a small, inconspicuous area of your car upholstery to ensure it won’t cause discoloration or damage.
Once you’re confident it’s safe, apply the enzyme cleaner generously to the affected area where mold or musty smells are present.
Allow the cleaner to sit for the recommended amount of time—this gives the enzymes a chance to break down the mold and odor-causing particles.
After the waiting period, wipe the area clean with a damp microfiber cloth to remove any residue.
For stubborn odors, you may need to repeat the process. Using an enzyme cleaner not only helps eliminate existing mold and odors but also discourages future growth, leaving your car smelling fresh and clean.
10. Prevent Future Mold Growth
Always dry your car’s interior after cleaning or spills.
After cleaning or using odor removal treatments, air out the car by opening the windows and doors to eliminate lingering smells and moisture.
Use a dehumidifier or moisture-absorbing packs to reduce humidity levels.
Ensure proper ventilation by cracking windows slightly when parked.
Regularly clean and maintain your car’s interior.

Does Rubbing Alcohol Kill Mold ?
Yes, rubbing alcohol (isopropyl alcohol) can kill certain types of mold and mildew by breaking down their cell membranes.
However, its effectiveness depends on the concentration of the alcohol and the type of mold.
Typically, rubbing alcohol with a concentration of 70% or higher is effective for killing mold on non-porous surfaces like glass, tiles, and metals.
How Rubbing Alcohol Kills Mold:
Dehydration of Cells: Alcohol disrupts the water content within mold cells, killing them.
Surface Cleaning: It removes light mold growth on non-porous materials and helps prevent regrowth.
Limitations of Rubbing Alcohol for Mold:
Porous Surfaces: Rubbing alcohol isn't effective for deep cleaning porous surfaces like wood or drywall, where mold can penetrate and grow internally.
Toxic Mold: It may not be sufficient for dealing with toxic molds like Stachybotrys chartarum (black mold), which require professional remediation.
Not a Long-Term Solution: It kills surface mold but does not remove mold spores or address the underlying cause of mold growth, such as excess moisture.
How to Use Rubbing Alcohol for Mold Removal:
Mix equal parts of rubbing alcohol and water in a spray bottle.
Spray the affected area and let it sit for 10-15 minutes.
Wipe the surface with a clean cloth or sponge.
Dry the area thoroughly to prevent regrowth.
