You need to start wearing a surgeon mask.

Next time your mate hands you their phone then make sure you have a pair of disposable plastic gloves at hand.

Here's why:

According to a study carried out by cleaning company Initial Washroom Hygiene mobile phones are seven times dirtier than a toilet seat.

And you know your best mate Frank or Linda who INSIST on those leather cases? Well, they're the mankiest.

They are the worst offenders because they harbour the most bacteria of all.

The study involved taking swabs from hundreds of phones using ultra violet light to show up the bacteria.

The manky parts are called 'bright spots' and while a toilet seat had 220 of those spots...a phone had 1,479.

Of the 2,000 surveyed nearly half admitted to talking the phone to the jacks but only twenty percent of that admitted to cleaning them afterwards!
