Uh oh. I have been scrubbing my hands with betadine before surgery for years and never let it dry.

I've run into the 'let it dry' approach before, usually applied to alcohol products. Would it be more palatable to assert that most disinfectants require some dwell time , wet or dry, to croak the more resistant organisms? probably more accurate, anyway. Regarding disinfection of intact skin, CDC research seems to identify chlorhexidine and povidone iodine (betadine) as the leading contenders. Quaternary ammonium salts like zephiran, were in vogue for this application in the seventies, not so much now.
Or there is the Arkansas orthopedics approach: make a paste of plaster dust and bourbon, and smear it on the infected part-the bacteria get drunk and stone each other to death.
