After going through a desert layer with no water, being 100% dirty most of the time (and the immune system behvaving funny).

I would like to introduce the concept of dust bathing.

Done by many animals including dogs, hamsters, horses,...

A method to clean themselves, helping against moisture, pests and oil (not sure if it also helps with crude oil specifically).

Just by rolling around in dry sand, which should be plenty around this biome.

It does not have to clean all the dirt away but it should be an option to reduce the dirtiness by a certain degree to avoid getting sick.
