1 Apply a hot and wet towel for a while before wiping (it is best to burn the towel, and be careful not to burn the skin).

2 vinegar (preferably white vinegar, because there is no color) stock solution should not be diluted. Dip it in a towel or cotton ball and apply it for a while.

Use of Band-Aids and Precautions

Before using the band-aid, check the wound for dirt residue. The band-aid should be kept dry and replaced immediately when it is wet, otherwise it is equivalent to soaking the wound in water, which not only fails to protect it, but becomes a hotbed of bacteria, which is not conducive to wound healing.

Don't use the band-aid for too long, because the outer layer of the tape is airtight, which may easily lead to secondary infection of the wound. In addition, the tightness of the paste should be moderate, which will make the wound airtight and cause anaerobic infection, and it is easy to block the blood circulation of the injured part and cause ischemic necrosis.

Band-AIDS are only suitable for superficial small wounds that do not need to be sutured, and the wounds are neat and clean with little bleeding. Deep and narrow wounds, such as those pierced by nails and knife tips, should not be bandaged, and should be exposed after hemostasis to prevent tetanus infection.

If it is an infected or suppurative wound with pus or secretions, sticking a band-aid will only cause poor drainage of secretions, which is conducive to the growth and reproduction of bacteria; Band-aid should not be used for wounds with severe trauma before debridement; Inflammatory wounds such as burns or tinea pedis are also not suitable for using band-AIDS.
