) used to manage hotels and knows which items in the room shouldn't be trusted by visitors.

on TikTok, the former hotel manager revealed why guests should avoid using certain hotel toiletries.

While sharing footage of refillable toiletry pumps, she said: ";I will never use these refillable shampoo and conditioner bottles that are in the shower.

"People could put anything in them, and I've seen Nair and God knows what else in there."

These types of pumps can be easily unscrewed, which means malicious guests could fill them with any type of product.

In the following clip, Melissa showed another type of toiletry pump that appeared to be securely locked.

She added: "Now, these I will use because if you look, you have to unlock them to open them and refill."

This is because guests won't be able to tamper with refillable pumps that have been locked.

One person wrote: "The shampoo thing stresses me out. I’m on the road all the time, and I keep my packing to a minimum by using hotel shampoo."

In the comments, Melissa said that some hotels, usually those with three or more stars, will still stock miniature bottles of shampoo and conditioner at the reception desk.

Other hotel staff members also shared their own advice in the comments.

One person wrote: "As a former housekeeping manager at Disney, I never use the glass cups in the rooms."

While a third person commented: "I worked at a resort and watched the housekeeper wipe the toilet then use that same rag to wipe off the coffee pot! I'm still disgusted."

While another person added: "After being a housekeeper at a hotel, I just never want to stay in one ever again."

Melissa also recently revealed why guests should avoid using the ice buckets in their rooms because people use them "for things that you don't even want to think about."

Meanwhile, this simple hotel mistake could result in you losing your room to someone else.
