Cleansing actually clears your vagina from all the microbes even the important ones that hold your corrosives levels under wraps. By removing these bacteria, you are abandoning yourself entirely unprotected against diseases. Vaginas are designed in a way that they don’t need much cleaning through soaps, as they produce a substance, which acts as a natural cleanser. So, washing the outer layer with unscented soap is just fine.
The same is true of any other types of cleansing. Your body was built to handle itself. You do not need any products or procedures to help things along.
