How did a medieval knight clean the rust off thousands of tiny iron chainmail rings after a rainstorm? Maintaining armor was a never-ending nightmare. Iron chainmail oxidizes and rusts incredibly fast when exposed to sweat and damp medieval weather. Trying to manually scrub 30,000 tiny interlocking rings with a rag was physically impossible. Instead, the knight’s squire utilized an ingenious, automated cleaning hack. They took a small, watertight wooden barrel and shoved the rusty chainmail inside. They dumped in a heavy mixture of coarse river sand and highly acidic vinegar. The squire would seal the barrel shut and violently kick and roll it back and forth across the castle courtyard for an hour. The acid dissolved the rust, while the coarse sand acted as a powerful abrasive, aggressively grinding the thousands of iron rings against each other until they shined like mirrors.
