#1- We really like. Could you try using differnt messages similar to "save lives"? We really like that theme of " remember the patient" #45 and 44 are very, very clever but "clean is ok" understates the importance of how important clean is. #14 would be great with a differnt message, similar to #1 #31 does not work for us because the hands seem to be clapping instead of read for a wash.
