Mold is a form of fungus that likes to grow in warm and humid environment. Molds produce tiny spores for reproduction. These tiny spores could grow anywhere where they become in contact and where the conditions are favorable.

These tiny spores could be very problematic. Respiratory problems or allergic illness could be triggered from getting exposed to large quantity of mold spores.

Eliminating mold growth is not an easy task. Although, you could try to control mold reproduction by controlling the humidity or moisture.

Where Molds Could Grow In A Car

Molds could grow anywhere in the interior of a car if the conditions are right. In older cars water could penetrate from the bottom of the car through openings (rust holes), the trunk could leak collecting water and condensation, or clogged evaporator drain tube could contribute to mold growth.

If you have a newer and normal operating car (that doesn't leak water) you wouldn't have to worry much about mold growth. If your car has a cabin air filter, change it as needed to help avoid promoting mold growth on the filter.

The following are the examples of water issues:

Small water leak: Small water leaks usually found in older cars where the bottom is rusty.

Major water leak: This is an extreme case of when the windows may have been left open during a rainy day.

Spare tire storage water leak: Most owners don't check the spare tire storage for water leak. It is hard to get access to, and it's not a typical routine.

Wet floor with mold: When water issues occur over an extended period of time, mold will start to grow.
