Yuck, The Inside Of Your Car Could Be Filthier Than Your Toilet

We hate to break it to you but your car is filthy. Like, really, really disgusting. Even if you’re a regular at the car wash and love the exterior shiny clean, the inside is massively dirty.

A new university study commissioned by Scrap Car Comparison has revealed that the inside of your car is dirtier than the average toilet – with the boot and driver’s seat often playing host to faecal matter!

The study, conducted by researchers at Aston University’s School of Biosciences, took samples from cars with varying ownership histories to establish bacterial contamination levels inside the vehicles, and to highlight just how thoroughly (or not) people actually tend to clean their cars. 

Every car studied contained faecal bacteria, such as E.coli, with the highest levels found in the car boot as well as on the driver’s seat.

The gearstick, dashboard and back seat also saw higher levels of bacterial contamination than is found on, or even inside, the average domestic toilet.

The steering wheel was found to be the cleanest area of the car, likely due to the uplift in hand sanitiser use, thanks to the pandemic.

Older cars were revealed to have higher bacteria loads than those that have been on the road for a shorter time.

The filthiest bits of your car 

1. Boot – 1,425 bacteria identified 

2. Driver’s seat – 649 bacteria identified 

3. Gearstick – 407 bacteria identified 

4. Back seat – 323 bacteria identified 

5. Dashboard – 317 bacteria identified 

6. Steering wheel – 146 bacteria identified 

Lead professor Dr Jonathan Cox says the findings should make drivers rethink how they clean their cars and especially, to start cleaning all food after transporting it in the boot.

He commented: “The results of this study are fascinating, as they help to show that despite cleaning our cars, the older they are, the dirtier they generally are.”

This is particularly true of the boot and driver’s seat, adds Dr Cox. “Many of us have placed loose food shopping in our boots, or dropped the odd crisp onto our seat, before picking it up and eating it,” he says, and he’s right. We’ve all done it, haven’t we.

But we need to change how we think about cars and cleanliness, he stresses. “Often, we will clean our cars based on whether they ‘look’ clean versus whether they actually are clean, but you would never even think about eating off of your toilet seat. Upholstery, in particular, should be given deep clean and I for one, will always clean any used car I buy in the future myself!”
