Most doctors say that it is best to let your vagina clean itself. The vagina cleans itself naturally by producing mucous. Women do not need to douche to wash away blood, semen, or vaginal discharge. The vagina gets rid of it alone. Also, it is important to note that even healthy, clean vaginas may have a mild odor.
Regular washing with warm water and mild soap during baths and showers will keep the outside of the vagina clean and healthy. Doctors suggest women avoid scented tampons, pad, powders and sprays. These products may increase a woman's chances of getting vaginal infections.This answer is based on source informatin from the National Women's Health Information Center
