I don't know about you, sweetheart, but just because you don't see something on me does not mean it is less than clean. I am scrupulously clean always. Everywhere.
I'm not specific to any one or two part to keep them clean. I think all visible parts should be neatly cleaned since they are visible and can change other's opinion about you..
