Hannah Dodd, from Widnes, Cheshire, used to use baby wipes in bid to rid herself of sweat caused by the recent blazing heatwave.
The 27-year-old would often throw away her favourite clothes due to the sweat staines.
She tried to think of ways to ease the problem and decided to settle for cheap t-shirts that could be easily replaced but not being able to use her favourite pieces on hot days left Hannah feeling deflated.
Dodd's search for a solution when she accidentally bought a box of panty lines.
“I went to pick up some sanitary towels during my online shop, but I selected small panty liners by mistake," Dodd told NeedToKnow.Online.
The accidental purchase turned into a genius idea. She decided to use the products to line the insider of her t-shirts.
“I didn’t know what to do with them but when the heatwave struck last year, I started using them to line the armpits of my shirts and I’m really glad I did.”
“Panty liners absorb the sweat and because of their anti-odour properties, they’re perfect for a heatwave.
“Sweat can cause yellow stains, as well as big damp patches and this trick has saved me a fortune because the armpits [on my shirts] never seem to be worn out anymore."
Dodd said the hack is actually 'an age-old housewives trick' but due to the 'stigma' surrounding periods people tend not to share it.
“It’s a shame because it has rescued so many of my clothes.
TikTok users often share their hacks on the video-sharing app and Dodd is no exception.
Although the hack is easy enough to complete, she decided to share the process on TikTok to show people another use for panty liners.
Hannah said: “I’ve used this trick in dresses for weddings and now I take them on holiday.
"I don’t won’t wear anything khaki or grey without trying this first, though.
“Some people have asked if I’m worried about them falling out, but it’s a panty liner – not a concealed weapon.
“You can literally throw it in the bin, strap on another and you’ve got a sweat-absorbing, odour-busting little trick, literally up your sleeve.”
She adds: “I think everyone should experiment with cleaning and clothing hacks, especially to find what’s comfortable for the summer.”
