Is it safe to use feminine wash daily?or an ordinary soap,such as dove,would be enough?

Never douche: Douching ("feminine wash") is not necessary for health or hygiene, and it increases the risk of vaginal infections. Don't do it, either with a feminine product, soap, or anything else. If you have symptoms that make you worried about a vaginal infection (discharge, odor, itching), douching won't cure it and could make it worse. See a doctor for professional diagnosis and treatment advice.
