Get a deep UV flashlight (280nm Nichia LED works very well) with a high pass filter on the end to eliminate any stray visible light it emits. Fire it up in your own home in the dark. Deep UV is great for making things fluoresce and the high pass filter increases the signal to noise ratio, so to speak.

You will be absolutely disgusted. There are drops of liquid and other flakes of random shit everywhere. There is no escape, it would be a Herculean effort to clean it all and keep it clean.

Not saying that hotels aren’t nasty, but you’ve probably got a bunch of similar stains in your home or apartment right now.
