There's nothing worse than walking into a room and finding your little darling has had a party with pens - on your newly-painted white wall.
For those who have been unlucky enough to experience this first-hand, you definitely need to get a load of this amazing life hack.
The video above shows a person spraying hairspray onto a white wall which has pen scribbled on it. They then wipe the wall with a damp cloth and the pen comes straight off.
According to the Mail Online, the clever hack was shared on a Facebook group for mums.
The mum who shared it wrote: "I just posted about getting permanent text off the wall and a lovely lady said hair spray!! Well thank you coz it worked wonders [sic]. WOW!!"
We don't know about you, but we're totally impressed.
