Hello
Following wil help you:
1.The vagina is a naturally self-cleansing body part, so douching isn't necessary to keep the vagina clean.
2.. Wash your vagina when you shower or bath with a gentle soap or cleansing bar
.3.. Do not wash around your vagina too often. Once a day is usually enough
These steps will help you maintaining your vagina clean & healthy.
Hope this helped
Thanks
