After parking at the gate XY in ZZZ and passengers deplaned; the cleaning crew got on the airplane. Half of them were not wearing masks. After having been reminded all but one put them on correctly. The last person was reminded multiple times by me (Captain) that it has to cover both nose and mouth. She walked to the back of the airplane without covering her nose. One person had a mask on with a vent; which I reminded her was not allowed. She seemed surprised but changed her mask.
Captain reported cleaning crew came onto plane after passengers left; but most did not wear face masks as per company instructions.
