If you’ve noticed calcium build up on your sink faucet, you’re not alone. Hard water — water with high levels of calcium and magnesium — leaves behind chalky white deposits around faucet bases, spouts, and aerators. Over time, these deposits can make your faucet look dull, restrict water flow, and even shorten its lifespan.
Fortunately, you can remove calcium buildup with proper cleaning. But if your faucet is older, corroded, or especially prone to buildup, replacement may be the smarter long-term solution. Modern faucets feature smooth finishes, better seals, and even self-cleaning spray nozzles designed to resist hard water damage. In this guide, we’ll cover how to clean calcium deposits, prevention tips, and the best premium faucets ($300+) designed for hard water conditions.

What Causes Calcium Build Up?
Calcium deposits — often called limescale — form when water evaporates and leaves behind minerals. The main causes include:
- Hard water: High mineral content leaves behind white, chalky spots.
- Poor drying: Water left sitting on faucet bases or spouts evaporates, leaving deposits.
- Old finishes: Pitted or corroded finishes trap minerals more easily.
- Clogged aerators: Minerals build up inside the aerator and reduce flow.
How to Remove Calcium Build Up on a Faucet
You can clean calcium deposits without damaging your faucet:
- Vinegar soak: Soak a cloth in white vinegar and wrap it around the faucet spout for 30 minutes.
- Scrub gently: Use a soft toothbrush to scrub away deposits.
- Aerator cleaning: Unscrew the aerator and soak it in vinegar, then rinse thoroughly.
- Baking soda paste: For stubborn spots, mix baking soda with water and apply as a scrub.
- Rinse and dry: Always dry the faucet completely to prevent new deposits.
Important: Avoid harsh abrasives or steel wool — they can scratch finishes and make buildup worse.
How to Prevent Calcium Build Up
- Wipe your faucet dry after every use.
- Install a water softener if you live in a hard water area.
- Choose faucets with smooth, corrosion-resistant finishes.
- Use faucets with easy-clean spray nozzles for kitchens.
