For those with a surgical wound that's draining, sterilized gauze is very helpful. I had surgery last week and I was sent home with gauze over the wound. But because of the discharge, that got soaked quickly. I have to change the dressing every day to keep the wound clean. Cotton sterilized gauze is working great. It absorbs very well, so the wound stays dry for an entire day, until it's time to change the dressing again. Cotton sterilized gauze is also affordable enough to use daily.
It's important however to wash the hands and wear gloves each time. Because when the gauze is touched, it's no longer sterile.
