Transcript
00:00Roman legionaries used aged urine, rich in ammonia, to help clean oxidized armor.
00:06Legionaries collected stale human waste because natural urea breaks down into aggressive ammonia over time.
00:13They combined standard military-issue vinegar with fine sand to scour away oxidized armor.
00:19While vinegar contains acetic acid, claims that legionaries used bladder stones to clean armor are historically unfounded.
00:26That acidic mixture effectively dissolved copper oxides.
