Clean the wound
Clean your wound thoroughly. Mix one teaspoon of table salt in two cups of warm water. Dip a wash cloth in the salt and water solution and clean the area around the septic wound. Salt is a natural antiseptic and will kill the bacteria in the wound. If a scab has developed over your wound, do not remove it. If there is pus under the scab, carefully apply very little pressure to squeeze it. Extract any remaining grime using sterilized tweezers. After thoroughly cleaning the septic wound, apply some antiseptic (hydrogen peroxide) on top of it using a cotton ball.
Dress the septic wound
It is recommended not to dress an infected wound unless there are pathogens flying around in the air. To dress the wound, apply liquid antibiotic on a cotton ball and place it on the wound. Using a cotton bandage, fix the cotton ball on the top of the wound. Wrap the cotton bandage loosely but properly and secure it using some tape.
If your wound is really serious you may also need to take some antibiotics to speed up the healing process. However, it is recommended to consult a doctor before taking antibiotics.
Make sure to check the bandage everyday to ensure that the wound is healing properly. If you notice anything unusual like discolouration or seepage coming from the wound then try the steps again to properly clean your infection.
