Next time you’re on the train and struggle to find a seat, don’t fret because after seeing this, you’ll willingly stand.

A traveller took to Reddit to show the sickening amount of dust on a Sydney train seat.

“They really need to vacuum these train seats,” user Empdizz wrote, alongside the video of him using his fist to whack the seat which spews out a dirty cloud of dust.

“I dislike placing my butt on those seats, let alone my bare hands… I admire your bravery,” one person responded.

Another added, “Do the same thing to the bus seats and you’ll see it too. Not just limited to the trains, but buses too.”

Watch the sickening footage above!
