Rust is when iron meets water and air, and decides to crumble into that sad, flaky brown powder—a chemical reaction, the science teachers would say. Galvanisation stops it by giving the iron a protective coat of zinc, like a good raincoat. But I tell you, all this I learned too late for my new balcony railing, which now blooms with orange stains after just one monsoon. Arre, what to do? Every evening, my ginger tea and I watch it spread, a perfect lesson I failed to apply.
