Clean markings on surfaces were a key component in Masur and Minsky's hierarchy machinery, which proved to be a powerful tool in the study of mapping class groups. In this talk, I will briefly discuss the connection with hierarchies, and I will explain how a natural analogue can be constructed for finite-type Artin groups.
