Key to a good car wash? Make the Prime Minister do it

No one can escape Sunday chores, such as cleaning the car - unless perhaps you're the Prime Minister's son.

But that's only because your dad does it for you.

In a video posted on SnapChat and subsequently Facebook, Max Key comes out through the garage of the family's Parnell mansion to show his dad, John, dressed in gumboots and a polo shirt washing the family's cars.

"Working hard to get my vote, are ya?," he quips.

His Prime Minister father responds: "There's an election coming up."

Key jnr then dances around, bending down and drying off the newly clean cars to the song Car Wash by Christina Aguilera then A$AP Mob's Yamborghini High.

After the chore's done, the effort is rewarded with a celebratory high five between the pair.
