For many, a hotel stay is seen as a luxurious escape from everyday life, but one hotel worker's claim may shatter this illusion.

A employee posting as a user on the travel forum has blown the whistle on the grim realities of hotel room cleanliness in a viral social media post.

They've exposed the often overlooked aspects of hotel cleaning routines.

The worker's shocking revelation began: "Most hotels do not wash the big duvet, they only wash the sheets," clarifying that at one establishment, the white duvet was cleaned only if there were visible stains.

Yet, the revelations grew more disturbing as the employee described the practices at their new job.

"The hotel I just started at is even worse. They have brown duvets that literally never ever get washed," came the alarming claim, reports .

The whistleblower didn't stop there, detailing varying standards in different regions.

"And in Asia, I think it's not common to have a top sheet in the bed, so you are just supposed to raw dog the dirty duvet," they continued.

"At least in the hotel I worked at in Europe, you could sandwich yourself between the two sheets and not really touch the big blanket once you're inside."

This eye-opening confession has ignited debates over the cleanliness of hotels and raised concerns among guests worldwide.

"Now every time I go to a hotel, I can't touch these blankets lol. But I'm sure some are actually good and wash everything, I hope."

The duvets aren't the only items that remain unwashed, as they claimed pillows could be just as unclean.

"Also the pillows underneath those pillowcases are filthy, covered in yellow/brownish spots, but I've only seen that here in South Korea," they said.

"The ones I've seen in the past seemed more waterproof. I'm grossed out lol, a pillowcase doesn't feel like enough to separate myself from that.

"And now I still wear my flip flops in the shower like it's a communal bathroom lol."

Others joined in the conversation with their own experiences, with one commenter noting: "Lol if you think the duvets are bad, think about the couches and stuff like that. Gets cleaned once a year, tops."

Another shared a rather unsettling insight: "I used to do network installs at hotels. Don't ever move the beds, it's better not to know. Sometimes it's used condoms, sometimes it's puke, sometimes it's both."
