How Do I Tactfully Address a Sensitive Hygiene Issue with a Subcontractor?

Hi HR seniors, my boss approached me regarding the head of a company we subcontracted to do some work for us. He was complaining that the head subcontractor has an unbearable odor, to the extent that they can't sit in meetings. He is asking for advice on how to diplomatically tell the head of the subcontracting company about his unbearable odor so that he can address it. These are personal matters that must be handled with caution, so I need your advice. Thank you in advance for your help.

Ask him to casually inquire, "Which body deodorant do you use? Yesterday, I purchased one from XXX company that had a very captivating scent. Why don't you give it a try?" I am not sure how the other person would take it, but they certainly won't be offended by this statement.

Hope this suggestion helps.
