What is the white buildup on my fixtures?

The white buildup on your fixtures is mineral deposits, primarily calcium and magnesium from hard water. This chalky, crusty residue forms when water evaporates and leaves behind dissolved minerals that were naturally present in Ottawa's water supply.

Ottawa has moderately hard water, with mineral content varying by neighborhood. Areas drawing from groundwater sources typically see more buildup than those on surface water. The white deposits are completely harmless to your health but can restrict water flow, damage fixture finishes, and create an unsightly appearance over time.

Regular cleaning prevents permanent damage to your fixtures. For light buildup, white vinegar works excellently - soak a cloth in vinegar and wrap it around faucet aerators and showerheads for 30 minutes, then scrub gently with an old toothbrush. For heavier deposits, remove aerators and showerheads completely and soak them overnight in vinegar. Commercial lime and calcium removers like CLR are also effective for stubborn buildup.

Prevention is key - wipe down fixtures after use when possible, and clean weekly rather than waiting for heavy buildup. If you're seeing rapid accumulation throughout your home, consider having your water tested. A water softener system can dramatically reduce future mineral deposits, though it's a significant investment ($1,500-$3,000 installed in Ottawa).

For fixtures with severe buildup that won't come clean or if mineral deposits are affecting water pressure throughout your home, it may be time to replace aerators, showerheads, or consult about water treatment options.
