The actual fact is that you will need to use an alkaline solution to clean your vagina, such as baking soda, to inhibit the growth of mold and control your condition. 2. Some women experience severe itching after using gynecological cleansing, probably because they are not accustomed to this cleansing solution and have an allergic reaction to the symptoms.
