The circumcision can be soaked in potassium permanganate solution. Potassium permanganate solution has strong oxidizing properties, so it also has a certain disinfecting effect. The main purpose of using potassium permanganate solution to soak after circumcision surgery is to disinfect the wound and prevent inflammation and infection. In addition, the use of potassium permanganate solution to soak is also conducive to the decreasing edema of the circumcision surgery. The potassium permanganate solution must be used in strict accordance with the instructions, generally in accordance with 1:5000 to make the ratio. Potassium permanganate solution is corrosive, so the concentration of the prepared solution should not be high, and the color should be light red, so that it is safer to use. After the circumcision surgery, you can use potassium permanganate solution for soaking, and then after soaking, you need to wash the potassium permanganate solution in time, otherwise the potassium permanganate solution will be colored on top of the penis skin, which is more difficult to remove.
