Your Car Interior Holds More Bacteria Than You Can See
Researchers at Aston University tested five used cars and found that the trunk carried 1,425 bacteria, the driver's seat 649, the gear stick 407 and the back seat 323. Every car tested had a higher total bacterial load than the household toilets sampled, and older cars carried more bacteria than newer ones. A quick vacuum doesn't touch most of that. Shampooing, extraction and cleaning high-touch surfaces does.
