ELI5: Eventually, where does all the dust in the world go?

Does it just get re-circulated? You clean your place and make your neighbour's place dirty, and vice versa?

It gets absorbed into the environment one way or another.

Dust lands in sea; either gets eaten or turns to sediment. 

Dust on land: hits the ground and stays dust, until it accumulates and becomes dirt (or dirt almost immediately on damp soil, or mud/sediment on wet soil, which would then just be dirt upon drying) 

Dust in the air does a bit of everything. Gets breathed in where it gets added to regular waste processing, or eaten in the case of very small creatures depending on what the dust is made up of. Lands on things and see above. 

Its all a big circle.
