Hard water carries dissolved calcium and magnesium that don't evaporate with the water. They stay behind as a chalky limescale film on any surface water touches repeatedly: tap spouts, showerheads, glass shower screens and commode bowls. In parts of the Valley drawing from groundwater or tanker supply, this buildup is faster and more visible than on municipal-only lines.
On chrome fittings specifically, limescale left to dry and get wiped repeatedly acts like a very fine abrasive, which is what actually dulls the finish over time. The hard water itself doesn't chemically damage chrome, but the mineral crust does if it's scrubbed rather than dissolved off.
The fix is mostly about habit, not equipment: wipe fittings dry after the last use of the day rather than letting water sit and evaporate on the surface, descale showerheads periodically by soaking the nozzle in a mild vinegar-water solution rather than scraping at deposits, and use a soft cloth rather than an abrasive scrub pad on chrome and glass.
For persistent whole-house scaling, a point-of-entry water softener is the permanent fix, but for most households the wipe-dry-and-descale habit above removes the vast majority of the problem at zero cost.
Key takeaways
- Limescale, not the water itself, is what dulls chrome: don't scrub it, dissolve it
- Wiping fittings dry after last use prevents most buildup before it starts
- A vinegar soak beats scraping for showerheads and taps
