There are a lot of dirty places on long-distance trains that are rarely disinfected. If you went into a compartment and saw that cleanliness reigns there, upon closer examination, you can see that they do not clean it so carefully.
Mesh pockets
Each bed in the compartment has mesh pockets. They are intended for newspapers, magazines, books, and other household trifles, but people throw garbage there and put dirty socks and underwear.
Therefore, it is worth refusing to use this pocket, since it is impossible to disinfect it. Better to avoid it and not put anything inside.
Tables
At first glance, the tables seem perfectly clean, but it is better to additionally treat them with antiseptic wipes. The fact is that some passengers use the tables not only for food. Dirty things are put on them, diapers are changed for children, and legs are also put to climb onto the top shelf of the compartment.
Pillows and blankets
If the thought creeps into your head that you are too lazy to tuck a pillow into a pillowcase and a blanket into a duvet cover, think about how much dirt and dust accumulate on the bed.
A huge number of passengers sleep without bedding and leave dirt, sweat, and particles of their skin on pillows and blankets. Therefore, all bedding should be used only with linen.
