How to Kill Mold in a Car

Mold can thrive in your car's moist interior.

Musty or sour smells wafting from your car's upholstery may indicate a mold problem. Mold can find its way into your car when a window is left open in the rain, washed upholstery dries improperly or containers spill. To prevent future mold growth, immediately wipe up all liquids that spill in the car. Use a hair dryer to dry out wet upholstery. Remove the mold from the car before it destroys the fabric and presents a health problem for the driver.

Things You'll Need

• Detergent
• Vacuum
• Bucket
• Bleach
• Brush

Instructions

1. Remove any debris or clothing from the car. Launder any moldy clothing in a warm wash with a detergent containing bleach. Vacuum the inside of the car with a car vacuum to remove any loose mold spores.
