How can I get rid of mold in my car?

If you have very much mold at all in your car, then you should wear a dust mask while you work on it. Some molds can be very serious health concerns when inhaled. With that said… Molds are actually fungi that breakdown organic matter. The mold has formed predominately due to the moisture level and warm temperatures inside the car. In order for you to be able to effectively work with the mold, you must COMPLETELY air out / dry out the inside of the car thoroughly. This can be done any number of ways including running the car with the heater or air conditioning on with two windows cracked open until the inside dries. There are small, inexpensive 110v dehumidifiers (made for use inside gun safes) that fit nicely inside of any car. Once the car is completely dry inside, you can vacuum away the mold. Aim a fan to blow air through the car – which simulates drying even in humid conditions. A small, soft brush will help in fabric areas. Finish by using appropriate, mild cleaners to get the final residue off of the harder interior surfaces like the dashboard. When you are done, spray the inside of the car with Lysol disinfectant spray and close the door for an hour. Be sure to keep the car dry on the inside from now on. Mold is all over, but when it develops enough for a person to see, it's a problem. You can purchase small packs of desiccant at the store to place under the seats and help ensure a much less humid space. Note: Chlorine bleach is excellent for killing mold, and is commonly suggested for destroying it. However, it is potentially quite harmful to colors, cloth, plastics, and aluminum.
