Actually, the wonderful thing about vaginas are they are self-cleaning! It is a myth that women need to clean their vaginas with douches or such products; normal cleaning and as you said "proper hygiene" can occur in the bath or shower, same with any part of the body, with water and regular or mild soap.
Cleaning the vagina beyond what is necessary in the bath or shower can actually cause more damage. In fact the "American College of Obstetricians and Gynecologists (ACOG) suggest that women steer clear of douching. All healthy vaginas contain some bacteria and other organisms called the vaginal flora. The normal acidity of the vagina keeps the amount of bacteria down. But douching can change this delicate balance. This may make a woman more prone to vaginal infections. Plus, douching can spread existing vaginal infections up into the uterus, fallopian tubes, and ovaries."
All healthy vaginas have a mild odor, and if you are experiencing an odor that is described as "pungent", it may indicate an infection, and it would be recommended that you talk with your GYN.
As noted by the original author of the post, "vaginal wind" or a "queef" may be caused by any number of activities, and is not a sign of poor hygiene (cleaning or not cleaning does not "cause" the wind to be noisy).
