It’s something we all use, but you could unknowingly be drinking some pretty gross remnants.
There’s no easy way to put it – there’s a chance that people have boiled their underwear in your hotel kettle to clean them by popping them in the kettle and flicking on the switch. The revelation has naturally sent social media into a meltdown.
The panic all started when Guy ‘Yug’ Blomberg posted on Twitter and Facebook “does anyone I know clean their underwear in a kettle when travelling”, stating his friend swears it’s something people do.
People have been quick to voice their disgust at the thought of it.
“This just wouldn't even occur to me in the first place,” one user said. “Like, why wouldn't you just boil some water, then pour it into another container?”
Another said: “Now there's something I wish I could un-see, never going to be able to use a hotel kettle again, because you know for one person to ask if it's ok, there must be many that do it without a second thought.”
Some saw the funny side of it.
“Next they will ask me not to use the iron to cook bacon!” one person said.
“If you put your underwear in there then there's no room to cook your pasta.”
One social media user said that participating in teenage footy trips over the years were enough for him to believe it.
“I've seen things done in hotel kettles that will stop you ever using them,” he said.
Senior lecturer in molecular biosciences at Massey University Auckland Heather Hendrickson told science and technology website Gizmodo that the practice was “super super super super gross”.
Boiling kills some microorganisms, but not all of them. Some bacteria form spores that can’t be killed with temperatures under 120ºC.
