If the concentration of potassium permanganate is controlled appropriately, washing the glans has no effect. If the concentration of potassium permanganate dilution is high, washing the glans in such a case has strong corrosive and oxidizing properties, which may cause the skin of the glans to ulcerate, and it is very difficult to grow well after the ulceration, and this situation has a great impact on the glans. If you prepare to wash the glans with potassium permanganate, the concentration must be controlled at 1:5000, or even lower concentration, and this concentration has very little effect on the glans. It is recommended to wash the glans with water normally, if there is inflammation, you can use 1:5000 dilution of potassium permanganate to wash, this concentration has no effect.
