What did Roman's use to clean their clothing and whiten their teeth?
The Roman poet, Quintus (Gaius) Valerius Catullus, wrote: "Egnatius, because he has bright white teeth, always smiles...whatever each man has urinated, he uses in the morning to rub his teeth and gums until they are red, so that the more polished those teeth of yours are, the more urine they proclaim you to have drunk." Catullus 39, The Smiling Spaniard. (See First Century Life: Cosmetae)
