Wound rubbing can be done with hydrogen peroxide, iodophor, medical 75% concentration alcohol, saline, with disinfection effect, which one to use depends on the condition and nature of the wound. Iodine volt can be used to clean the wound, it is less irritating, low risk of scarring, can form a protective film outside the wound to ensure complete healing, methyl violet solution and mercury bromine red solution can also be disinfected. If there is a foreign body or pus in the wound site, it should be rinsed and disinfected with hydrogen peroxide, which is more irritating than iodophor and can destroy necrotic tissue and kill internal viruses and bacteria, and the broken tissue should be removed as much as possible to ensure that the new granulation tissue can grow normally. After the wound is cleaned, it should be treated with saline for deep disinfection, and the wound and the skin around it can be wiped with iodophor. Alcohol is more irritating and usually does not come into direct contact with the wound, but can only be used to disinfect the skin around the wound.
