Recent evidence suggests that even an antibacterial soap may not be a good idea as it kills the "good" normal bacteria and make way for virulent bacteria to move in. An example of this is the disease C-diff that makes some people really sick when the prescribed antibiotic (say for some kind of pneumonia) destroys normal bowel bacteria, allowing a dangerous bacteria to get control. Stick with whatever shower soap you ordinarily use. Remember that you live in harmony with your good bacteria and germs. Eliminating them is not neccessary, probably can't be accomplished with soap anyway, and may be undesirable.If you are still unsure, check in with your surgeon and follow his or her advice.Best wishes for an uneventful recovery and excellent result down the road!!
