According to the spokeswoman of vaguely-European descent, you'll feel ready for "l'amour" after using the "FDA cleared" WaterWorks. The device, pictured below, is used by filling the bag with body temperature tap water and fully inserting the stainless steel end into the vagina, as shown in this animation from the company website.
According to the U.S. Department of Health and Human Services, most American doctors do not recommend douching, and douching will not get rid of bad vaginal odor. But according to the company website, WaterWorks isn't like douching at all because it only uses low-pressure tap water. The "science" section explains:
The combination of a stainless steel soap bar and tap water is used by chefs as the most effective way to eliminate odors such as garlic, onions and fish from the hands of food preparers. WaterWorks uses the same principle to reduce or eliminate vaginal odor.
