Removing Hard Water Stains from Fixtures
Hard water mineral deposits — the white, chalky, or rust-tinged buildup on faucets, showerheads, and shower glass — are a near-universal issue in Ontario homes. The Great Lakes water supply and southern Ontario's groundwater are both moderately to heavily mineralized, meaning calcium and magnesium deposits form quickly on any surface where water sits or evaporates.
The Effective Method: Acid Dissolves Minerals
Mineral deposits are alkaline — they're dissolved by acid. The two safe household acids are white vinegar (5% acetic acid) and citric acid (available in bulk at Ontario grocery stores and Bulk Barn). Commercial descalers like CLR (Calcium Lime Rust) use stronger acids and are effective for severe buildup.
Faucets
- Soak a cloth or paper towel in undiluted white vinegar
- Wrap it around the faucet and leave for 20–30 minutes (longer for severe buildup)
- Scrub with a soft toothbrush — do not use abrasive pads on chrome, which scratches
- Rinse and buff dry
Showerheads
Fill a plastic bag with white vinegar, submerge the showerhead, and secure the bag with a rubber band. Leave for 30–60 minutes. Remove, rinse, and run hot water to flush the spray holes. For detachable showerheads, unscrew and soak in a bowl of vinegar.
What Damages Chrome
- Abrasive scrubbing pads: Scratch chrome permanently
- Extended CLR exposure: CLR is effective but should not be left on chrome longer than 2 minutes — rinse thoroughly
- Bleach: Does not remove mineral deposits and damages chrome finishes
Prevention
Wiping fixtures dry after use is the single most effective prevention — no standing water, no deposits. A weekly wipe with a diluted vinegar spray prevents buildup from establishing between deep cleans.
