In recent time I've noticed the Batcave is always incredibly clean, but inside the Batcave are living bats. How does Batman keep it clean from the guano ? or does Alfred work all the day cleaning the poo?

The extensive cave system underneath Wayne Manor is quite large. No doubt when Batman started placing equipments and lighting into the Batcave the bats were compelled to go deeper into the cave (or further from Batman's operations).

The various changes to the environment caused by the equipment, primarily noise and temperature, would have made for a less desirable living space for most of the bats. They just relocated to a different part of the caverns.

I recall once where Alfred became ill due to frequent exposure to bat guano.

There are other uses:

    I recall seeing an issue in the Bruce Wayne: Murderer? storyline where Alfred talks about cleaning the bats' dejects. Can't recall the exact issue or quote, though,

In the DC universe superheroes never have to stop to use the restroom. This applies to the bats in the Batcave too, unless the plot dictates otherwise.


According to the DC Visual Dictionary, the bats were a constant nuisance to

"Alfred's fastidious cleaning"

So the short answer is that Alfred was responsible for cleaning the Batcave, along with shoveling bat poop.

According to Blue Beetle vol. 7, issue #7, the floors at least can just be sprayed with a hose.

Jaime Reyes apologises for throwing up in the Batcave and Batman says the floors hose clean.

(By "people", he definitely means "sidekicks", doesn't he?)
