Cleaning is not one category
Separate sanitation learning, normal shop upkeep and unrelated personal errands.
Search advice often collapses sanitation learning, shop upkeep and unrelated errands into one cleaning stereotype. That loses the distinction between professional practice, studio operations and requests that may have no training connection.
Professional sanitation and contamination-control learning
This is directly connected to safe tattoo practice. The relevant training content and any formal requirements should come from the shop's professional process and official health or licensing sources, not apprenticeship folklore.
General shop cleaning and support
A working studio has shared operational work, and an apprentice may be asked to contribute depending on the arrangement. That does not make every cleaning task a licensing requirement or prove that the task is the educational purpose of the apprenticeship.
Personal errands or hazing
Fetching personal items, unrelated chores or hazing are not automatically professional training requirements because someone calls them tradition. Ask how a requested responsibility connects to training or the professional operation of the shop.
A better question than whether apprentices clean
Ask what the responsibility is, who assigns it, how it connects to professional training or studio operation, and whether anyone is claiming it is required by a regulator. A training arrangement can include operational work while still needing a clear educational and progression component.
