These have no disinfection effect. What does disinfection mean? Disinfectants are used to disinfect the environment, generally used in surfaces, walls, floors, doors and windows, tableware, toilets and so on. And the new Jieer disinfectant has achieved the same effect. Skin disinfection can be applied to the wound with 75% medical alcohol. But it can also be used on chopping boards and knives, and so can hydrogen peroxide. These can be bought in pharmacies and are not expensive. If children's toys are disinfected, they can be wiped with alcohol after cleaning, and the rooms where infected patients have lived can be disinfected with 84 disinfectant or hydrogen peroxide. Gynecological disinfection can use diluted iodophor.
