Do not boil your underwear in hotel kettles

You know those "amazing household tips" where you descale showerheads with vinegar and a sandwich bag, or lift carpet indentations with ice cubes, or whatever? Well, I've just found out that a common one in Australia, allegedly, is "wash your underwear in hotel kettles." I honestly don't know if I believe it, but Gizmodo Australia claims it is a thing and, if it is, could you please not?

I reached out to some experts on the matter to find out if the simple fact the underwear is literally boiling means this actually a safe thing to do, or nah.

Dr Heather Hendrickson is a Senior Lecturer in Molecular Biosciences at the Institute of Natural and Mathematical Sciences at Massey University in Aukland.

She knows what she's talking about.

"It is super super super super gross," Dr Hendrickson says. "Please tell your friend to knock it off! Boil the water and pour it into the sink for washing items. Don't put your dirty underwear into the kettle!"

Australia! Explain yourself!
