To answer your question, no. And she should not really be using soaps.. It can upset the PH balance in the vagina and cause an infection. Just a thought.
Summer's Eve is the best feminine wash in my opinion. It has a great light scent and they even have some for sensitive skin. It's a lot LESS harsh than regular soap.
Ditto to the other ladies' comments
i am also a very big cleaner . i know douching is bad but i dont use the vinegar stuff i empty it out and fill with hot water and clean. i have gotten pregnant 4 times with this .
