Hi, how to clean a stitched/glued area?

Depends. Your doc should have provided you with instructions on how to take care of it. The problem is that it depends on the location of the wound, the type of wound and the type of repair done. Normally, there is a period after repair that the wound needs to stay dry and covered. After that exposure to water is recommended but when, again depends on the wound, location and type of repair.
