Isn’t it possible that the hand-held bidet could be dirty from the last person using it?
If used correctly the bidet should remain clean; as it is not necessary for it to be placed any closer than 5 centimeters to the parts of your body being washed, and always from above. It is never used for directing water up or from inside the toilet bowl! This is the sole domain of Under-Seat Bidets, Non-electric or Electronic Bidets which are of particular use to people with a restricted range of body movement, or other problems that make traditional Hand-held Bidet cleaning methods difficult. To fully understand the safety aspects of using hand-held bidets, please read the information about Backflow.
