In Wisconsin, Can a Landlord Charge Me for Carpet Cleaning:

Under Wis Admin Code ATCP 134.06(3)(c) landlords cannot withhold from a tenant's security deposit for normal "wear & tear" even if included in a nonstandard rental provision. This means that a landlord cannot automatically deduct the cost of routine carpet cleaning from a tenant's security deposit unless the cleaning is necessary as a result of damage, waste or neglect and is, therefore, something more than normal wear & tear.

It is acceptable to indicate in the rental agreement that the tenant is responsible for providing and paying for routine carpet cleaning. See DOJ letter to DATCP dated 7/31/13. But, if the tenant fails to do so, a landlord still cannot deduct the cost of routine carpet cleaning from the tenant's security deposit.
