After a cylinder is rehoned with a flex hone or rigid hone a scrub with soapy water and a nylon bristle brush is preferable to cleaning with solvents. This is because small bits of the abrasive material can be lodged inside the bottom of the newly honed scratches. A scrub with hot soapy water dislodges these particles better than a solvent. This needs to be then dried and then followed up with a protecting oil (WD-40, etc) to prevent flash rusting, which will start almost immediately.
With a new brake rotor, brake cleaner should be fine.
