A savvy mum has shared a genius hack to keep your bed sheets crease-free in a matter of seconds – and it doesn't cost a penny.

Mum-of-two Mila, from Melbourne in Australia, showed her fans on TikTok @mama_mila_ how she keeps the sheets looking pristine without ironing them.

In the clip viewed more than 261,000 times, Mila explains all you need to use is a spray bottle with water inside.

She first takes the clean bed sheet out of the wardrobe and places it on top of the bed.

Mila then sprays the tap water across the sheet until the folding crease starts to disappear.

To finish, the cleaning guru starts tucking the bed sheet under the mattress.

She says: "Continue to spray a fine mist of water as you tuck the sheet tightly. You can see the creases reducing."

Within seconds, the white bed sheet looks completely crisp as if it has been ironed.

Viewers were stunned when they found out all they need is water.

One said: "Brilliant! What is this wizardry?"

Another joked: "This is why hotel sheets have a slightly damp feeling!"

"Only with water?" a third asked. "I can't believe this."

Mila also revealed that the trick is used in many hotels to save time on ironing.

She previously shared a cleaning tip on removing the stubborn dirt stuck in between the shower tiles using a £3 home-made product.

The bathroom floor transformed completely after a quick rub using two DIY household items – half a cup of baking soda and a third of a cup of hydrogen peroxide in a jug.
