Apparently this is the one thing you should NEVER use in a hotel room

Don't worry, the towels and sheets are safe!

But according to research by ABC News it's actually the water glasses that are the "no-go".

ABC News investigated 15 hotels across America, and found that 11 of them failed to remove dirty glasses from rooms, even though they had been used by previous inhabitants.

YUUUUCK!

A lot of the hotel maids just rinsed them out and dried them with a towel, instead of actually replacing them!

One maid used Lysol mildew remover; that's a mold removal bleach and is extremely poisonous when consumed.

Woooah, let's stick to drink bottles...
