Use hydrogen peroxide to clean the wounds out....
I’ve had many skin surgeries and the nurses have told me multiple times to never to use hydrogen peroxide to clean the wound out.
It is fine for cleaning blood up and taking it off your clothes but it kills the cells closest to the wound that will be among the first to mend to each other, so that it really slows down the healing process.
Diluted iodine is really best for killing the germs in the wound.
I also learned that quick first aid for a cut while fishing is to urinate on the wound. ..
Well it should be sterile. Hopefully.
I have seen deck hands use straight bleach.
And I thought iodine,even diluted would sting like crazy!
