For years, our toilets were much maligned as being the dirtiest things in the house.
But as time has gone on, it's become clear that a lot of everyday objects are absolutely heaving with nasty bacteria.
Water bottles and computer keyboards are just two examples of the worst offenders. In fact, comparatively, your toilet seat is shaping up to be an oasis of hygiene.
Now there's something else to add to your list - your car.
According to new research, most cars are home to at least four times more bacteria than the handrail of a public bus.
It's worse news for parents, too.
Thanks to tests carried out by car care brand Simoniz, a vehicle owned by a father-of-four was found to have 23 times the bacteria of the bus handrail.
The poor dad's car was also found to house double the bacteria on a TV remote and over six times that found on the handle of a kettle in an office kitchen.
Many of the cars swabbed also had the same levels of bacterial infection as on a toilet flush handle.
Further bad news came when the experiment found there were levels of toxic yeast present. These, in turn, can cause allergic reactions and skin, eye, throat and lung irritation, particularly for those susceptible to allergies and asthma.
Most cars are breeding grounds for these.
"The results of the experiment, although pretty disturbing, are not entirely surprising, particularly when it comes to high levels of bacteria found in the car," hygiene expert Luke Rutterford told Pretty52 .
"Areas in the car, such as the gear stick, control centre and steering wheel are high frequency touch points, and become an area of continuous bacterial contamination.
"This is more so when drivers eat and drink in the car which can allow general debris to become a breeding ground of bacteria," continued Luke.
So while the weather's nice, why not show your car some TLC?
