It is best not to use peroxide on scrapes. Soap and water is better for cleansing scrapes as it seems to burn less. A thin film of anti-bacterial ointment such as Neosporin or Polysporin may be used if you desire. This ointment is available at the drug store. There are differing opinions about the use of ointment.
Some doctors say it keeps a wound too moist and slows healing.
The key is to use a thin film. Don't gob it on the wound. A dressing is especially good if there is drainage from the wound. As much as possible, keep the wound clean and dry. Do not get the wound wet .
