What is a reliable treatment to get rid of staph colonization?

Staph aureus: A combination of Mupirocin ointment in the nares twice a day for a month, combined with bathing solely with a soap containing hexachlorophine (if you use another soap you will wash off the thin layer it creates on the skin and render it ineffective) to try and eliminate the skin surface contamination. This is only effective in slightly more than half of patients, but worth trying.
