How to Remove Hard Water From Faucets and Fixtures

That white, crusty ring around your faucet isn’t dirt. It’s hard water minerals left behind every time water dries on the chrome.

Key takeaways

  • White crust on faucets is mineral buildup.
  • Spotless X2 works on chrome, metal fixtures and porcelain.
  • Test special finishes in a hidden spot.
  • Wipe fixtures dry to prevent buildup.

Why fixtures crust up

Faucets are wet many times a day, and water collects around the base, handles and aerator. Each time it dries, minerals stay behind. The crust builds fastest where water pools and can’t drain away.

How to clean it

Spotless X2 works on faucets, metal fixtures, chrome and porcelain.

Safety first

Spotless X2 is a strong acid cleaner: its Safety Data Sheet lists it as causing severe skin burns and eye damage. Wear gloves and eye protection, keep it off your skin, and read the label before you start. Every sheet is on our SDS page.

What you’ll need

  • Spotless X2
  • Small microfiber pads
  • Microfiber towels
  • Old soft toothbrush for edges
  • Nitrile gloves
  • Eye protection
  1. Dry the fixture so you can see the buildup.
  2. Use a small dab of Spotless X2 on a microfiber pad.
  3. Work it over the crust, getting into the base and edges. Heavy buildup may need a second pass.
  4. Rinse well and buff dry with a clean microfiber.
Pro tip

Test on a hidden spot first if your fixtures have a special finish (brushed, matte black, brass or coated). Follow the fixture maker’s care instructions.

Keep it clean

Wipe faucets dry after use when you can. It takes seconds and stops the crust before it starts.

Aerators and spouts

The aerator at the tip of the spout can clog with minerals, which changes the water flow. Many aerators unscrew by hand. Check your faucet’s instructions before removing it, and clean the outside of the spout with a small amount of product on a pad.

Common mistakes to avoid

Using it on special finishes without testing. Test matte black, brass and coated finishes first.

Abrasive scrubbers. They scratch chrome.

Leaving product sitting. Rinse well.

Ignoring drips. A dripping faucet keeps building crust.

A simple care schedule

When What to do
Daily Wipe the faucet dry when you can.
