Q. You wrote recently about using milk of magnesia as an underarm deodorant. My husband uses the antimicrobial skin cleanser, Hibiclens. He puts it on his armpits for 10 minutes each morning, then washes it off. This has solved his body odor problem.
Hibiclens does not require a prescription. In some drugstores you do have to ask for it.

A. Since underarm odor is largely the result of skin bacteria fueled by sweat, getting rid of the bacteria each morning seems like a logical approach. Hibiclens is an antibacterial cleanser containing chlorhexidine. Health care workers often use it to avoid spreading germs from patient to patient.
