Study shows which parts of a car’s interior is most riddled with germs

Motorists told to clean up their act as research shows how car interiors can be breading grounds for germs

Study shows which parts of a car’s interior is most riddled with germs
Certain areas of a car’s interior are hotspots for bacteria to grow, if the car is not regularly cleaned.

New research has revealed the true extent of how dirty UK car interiors really are and how many drivers are allowing bacteria to multiply.

An experiment conducted by auto retailer Motorpoint, which involved taking swabs from 20 separate areas of the interior.

Using agar filled petri dishes, each sample was left for five days before analysis revealed which areas had the most bacteria.

Visible bacteria

Bacteria growth taken from a sample out of a boot.

The areas with the most visible bacteria were the boot, driver footwell, seatbelt and handbrake.

The cup holder, inside door handle and radio volume button also accumulated white and black mould.

The cleanest areas turned out to be the rear-view mirror, steering wheel rim and gear stick.

Alison Weatherley, head of marketing at Motorpoint, said: “The results were quite revealing and showed that maybe we need to clean our cars a little more often that we currently think is acceptable.”

Cleaning habits

Research suggests that on average, British drivers clean the outside of their car eight times a year, or approximately every six weeks, but the interior every five.

Shockingly, almost one in five Brits clean the inside of their car three times a year or fewer, and almost one in ten cleaned the interior just twice a year or fewer.
