For smelling vagina, do the following: 1. Only wash the vulva (the outside external area) with warm water or a mild, unscented cleanser. Avoid washing inside the vagina. 2. Never use douches, feminine deodorants, or scented soaps. These disrupt the natural pH balance and encourage bad bacteria to grow. 3. Change out of wet clothing (like swimsuits or sweaty workout gear) promptly. Wear loose-fitting clothes and breathable cotton underwear. 4. Eating foods with live cultures (like yogurt) may help maintain healthy vaginal flora. Some people also use Vitamin C vaginal suppositories to support pH balance.
