A new study took swabs from 20 parts of the inside of a car to figure out where the most germs are.
The samples taken showed that the steering wheel - the most touched part of a car - was one of the most germ-free areas swabbed, while the trunk was the most contaminated.
The other areas with the most visible bacteria were the driver footwell, seatbelt button and the handbrake. The swabs also looked at spots in the car that accumulated mold: the cup holder, inside door handle, and radio volume button all tested positive for mold.
Surprisingly, the three cleanest areas that had the least germs were ones owners come into contact with most frequently: the rear-view mirror, steering wheel, and the shifter.
