When a chick is nice and wet, throw a couple digits inside her vag. Take those wet fingers out, and give the 2 finger sniff across your mustache line. Leaving a glistening trail of vag juice across your upper lip and below the nostrils for one to smell and enjoy. Hence, the Clean Sanchez!
Alternatively, it can be done on either yourself or on the chick you just fingered
