There is one type of mold called black mold or Stachybotrys chartarum and chlorohalonata species, which are fatal even by just inhaling the spores. Be careful when leaving your car out in the open, especially if there is no roof above it.


If you accidentally leave your car windows open and it rains, expect that the next day molds will form in your vehicle. It only takes a few minutes for mold to thrive in moist areas. In case mold forms, don’t worry, here are some tips on how to clean mold out of a car.

Steps on How to Clean Mold Out of a Car

There are a couple of ways that you can get rid of mold in your car. No matter which methods or products you use, keep yourself protected by wearing household cleaning gloves and a surgical face mask. Here are the steps on how to clean mold out of a car:


Since mold thrives in moisture, bring your car to a sunny spot and open all the doors and windows. This allows the sun to dry out any wet or damp areas and air out your car.


Remove seat covers and carpets. We can use two different mixtures to kill the mold from seat covers and carpets before washing them.

  • You can use eight parts distilled white vinegar mixed with two parts water and put them in a spray bottle.
  • You can also use ¼ teaspoon oil of cloves mixed with ½ cup of white vinegar, one tablespoon of baking soda in 1 quart of water.

Spray the white vinegar or oil of cloves solution on the car seat covers and carpets and let them sit for 20 minutes or longer. You can also use these mixtures to spray on your car’s interior such as seats, dashboard, steering wheel, and on the air vent.

Don’t forget to spray onto those hard to reach spaces and even under the seats. For stained seats and carpets, sprinkle some Borax powder on the area and leave it for 10 minutes then vacuum or brush it off.


Wipe off the surface with a clean cloth to remove the dried up mold. You can also use a vacuum to remove them. Make sure to throw away the cloth and clean out the vacuum bag as these contain mold spores.

If you have a vacuum for rv , that's perfect , you can use it to remove all them.​


Wash the seat covers and carpets with regular detergent. It is best if you add some Borax powder to kill any remaining mold spores. Dry them out in the sun for best results.

If you have no way of washing the seat covers and carpets, you can mix a packet of uniodized salt in a bucket of water and spray it on. Make sure you spray all the surfaces and not just the mold-infested spot, so all spores are killed.

Dry them out in the sun until salt crusts form then vacuum or brush them off.


After removing the mold in your car, it will smell like white vinegar or oil of cloves. Oil of cloves will not have an overpowering smell but vinegar will. Place a small dish of baking soda or a dehumidifier inside your car to get rid of the smell and additional moisture.


Spray your car with air freshener product to get rid of any bad odor and kill bacteria. Leave the car doors open out in the sun to air out your car and dry any moist spots.


Vacuum the interior of your car to clean out dust and other particles before returning the seat covers and carpets.


The above steps seem like a lot, and you might wonder if it would be best just to bring your automobile to a professional cleaner. Well, it really depends on how much mold there is. If there are just minor areas, it saves you time and money to bring it to a professional cleaner.

    my rented cottage was just found to be full of mold under the 16 in crawl space of the whole thing. this didn’t happen over night, even because my water froze in January and I had 4 inch of water in most of the place. couldn’t get a wet vac fast enough, it just disappeared through the floor, less then 20 minutes,all I could use to soak up the water left in the carpet, as it was 3 am. towels and paper towels, newspapers cardboard.
    Land Lady could not get a hold of her cleaner. then again, I kept telling her I heard water running and she told me to mind my own business. August 13 the hot water tank started squirting inside under my sink. I went outside and took the crawl space board off and the hot water tank was leaking like crazy, so bad it had a sand funnel that looked like a tornado. Again, this just didn’t happen. I need help and no one will help me. I am getting sicker, as I have nowhere else to go. I also have a dog, he has been here since September 1. with all this said dog and I have been back in forth from house and car. I just found out mold spores can travel on dog, so I say what do I do now and how do I get the mold spores out of my car and dog????? Please HELP ME. Thank You Lonni
