Blood stains are among the most difficult stains to remove from clothing - something which most women will be all too familiar with.
However, one woman has revealed the ultimate cleaning hack online, which has been dubbed a "life saver" for some ladies during that tricky time of the month.
Brush By Four Nine shared the hack on how to remove period stains from underwear using just hydrogen peroxide and cold water.

A video showing the transformation was shared on the Instagram page, which is run by UK blogger Rosie, showing a pair of hands soaking the pants in cold water before scrubbing the blood stains with hydrogen peroxide.
The underwear can then be washed normally in order to fully remove the stains.
One impressed follower branded the hack "life saving," while another person confirmed it "works like a charm."

A third commented: "This is a great tip, didn't think to use hydrogen peroxide."
Others added their own suggestions into the mix, with several suggesting using cold water and soap, lemon juice and even toothpaste should do the trick.
Despite the fact some users branded the video as "gross", others praised Rosie for normalising period blood.

"I love that they're showing real blood instead of the fake blue sh*t," one person commented.
"The fact that we are taught that something we can't control should be hidden and never spoke about and shamed is the real gross thing here."

Another added: "People getting gross about blood!
"It's the same blood that flows in our bodies - just because it's on someone's panties all these idiots are getting worked up!"
For anyone who wants to try out the hack at home, you can grab a 200ml bottle of hydrogen peroxide for as little as £1.49.
