How do I remove hard water buildup from my faucet?

White vinegar is the most effective and safe method for removing hard water buildup from faucets. Soak a plastic bag filled with white vinegar around the faucet aerator and spout, secure it with a rubber band, and let it sit for 2-4 hours or overnight for heavy buildup.

For the faucet body and handles, create a paste using baking soda and water, then scrub gently with an old toothbrush. The mild abrasive action helps break down mineral deposits without scratching the finish. After scrubbing, wipe clean with a damp cloth and dry thoroughly to prevent new water spots from forming.

Ottawa's water is moderately hard (around 130-150 mg/L), so mineral buildup is common throughout the city. For stubborn deposits, you can also use CLR (Calcium, Lime & Rust remover) following the manufacturer's instructions, but test it on an inconspicuous area first as it can damage certain finishes like brushed nickel or oil-rubbed bronze.

Prevention is key - wipe down faucets after each use and consider installing a water softener if hard water is affecting multiple fixtures throughout your home. If the aerator is completely clogged and won't come clean, it may need replacement (usually $5-15 at hardware stores).

If you notice reduced water pressure even after cleaning, or if the faucet cartridge seems damaged during cleaning, that's when you'll want to call a professional. Sometimes hard water buildup indicates internal component wear that requires replacement.

For persistent hard water issues affecting your whole home, Ottawa Pro Plumbing can assess your water quality and recommend solutions like water softeners or filtration systems.
