If you’ve noticed a calcium deposit on your sink faucet, you’re dealing with a very common hard water problem. Over time, chalky white or grayish buildup forms around the base, spout, and aerator. This limescale not only makes your faucet look dirty, but it can also clog aerators, reduce water flow, and wear down the faucet finish.
The good news: you can remove calcium deposits with simple household products. But if your faucet is old, corroded, or especially prone to buildup, a replacement may be the smarter choice. Modern faucets feature smoother finishes, better seals, and water-efficient technology that resist calcium buildup. In this guide, we’ll cover causes, cleaning tips, prevention strategies, and the best premium faucets ($300+) for homes with hard water.

What Causes Calcium Deposits?
Calcium deposits, also called limescale, form when hard water evaporates and leaves minerals behind. The main causes are:
- Hard water: High calcium and magnesium levels lead to chalky residue.
- Standing water: Droplets left on faucet bases dry and form white spots.
- Aging finishes: Older faucets develop micro-cracks where minerals collect.
- Clogged aerators: Minerals accumulate inside the spout and restrict flow.
How to Clean Calcium Deposits on a Faucet
You can restore your faucet’s shine with a few simple steps:
- Soak with vinegar: Wrap a vinegar-soaked cloth around the faucet spout and base. Leave for 30–60 minutes.
- Scrub gently: Use a toothbrush to scrub away softened deposits.
- Clean the aerator: Unscrew the aerator, soak in vinegar, then rinse thoroughly.
- Baking soda paste: For stubborn spots, scrub with a paste of baking soda and water.
- Dry thoroughly: Always wipe the faucet dry to prevent new deposits.
Tip: Avoid abrasive cleaners or steel wool — they can scratch your faucet and make it more prone to future deposits.
How to Prevent Calcium Deposits
- Dry your faucet after each use.
- Install a water softener to reduce minerals in your water supply.
- Choose faucets with smooth, corrosion-resistant finishes.
- Clean aerators monthly to prevent clogs.
