The most important thing about cleaning the vulva with potassium permanganate is that the concentration of potassium permanganate is configured to 1/5000 in order to achieve the disinfection effect, which is a strong oxidizer, so it has a sterilizing effect. For example, you can use half a basin of water with a little bit of potassium permanganate into the water to make the water appear light red. In addition, if the concentration is too strong, it may cause damage to the skin and mucous membrane.
