The Cleaning Station is a machine where encased fossils, encased nest fossils, (and eventually also tar, permafrost and coprolites. See Fossil Ores) are washed to reveal their secrets. The Cleaning Station can be filled with up to 8 buckets of water.
Encased fossils mostly yield the fossilized bones and various body parts of dinosaurs and other very old animals, and encased nest fossils yield 0-7 fossilized eggs per unit.
Once dinosaur bones or eggs have been obtained from the Cleaning Station, they can be placed in the Fossil Grinder.
