How to Easily Clean Calcium Buildup on Faucet

Calcium buildup on faucets is a common problem caused by hard water.

To clean shower heads and faucet aerators that have become blocked by calcium deposits, you can use an acid-based cleaner like vinegar or CLR. Soak the affected parts in the cleaner—for between 4 and 24 hours. After soaking, scrub away the calcium buildup with a brush, rinse everything thoroughly, and reassemble.

* Some surfaces, such as brushed nickel, may be damaged by strong acids. Read your manufacturer's instructions to prevent damage.

Let’s break down each step so you can make your faucet look like new again.

5 Easy Steps to Clean Calcium Buildup on Your Faucet

Step 1: Identify the Problem

Before you get started, check if calcium buildup is the issue. You’re looking for:

• White, crusty deposits around your faucet or shower head.

• Reduced water flow or uneven spraying.

If that sounds familiar, it’s time to roll up your sleeves.

Step 2: Remove the Problem Areas

Most calcium buildup occurs in the aerator (the small piece at the tip of your faucet) or shower head. Use pliers to gently unscrew these parts. If they’re stubborn, you might try a scrub brush around the rim of the threads.

Using a silicone or rubber gripping pad can help.

Be careful if using tools such as channel locks or a pipe wrench as they will damage the surface. You can use a towel to place in between the tool and the faucet surface to prevent scratches.

Run hot water through your faucet or shower without the aerator or showerhead on, for about 30 seconds, to clear any sediment buildup in the pipes.

Step 3: Choose Your Cleaning Method

Calcium buildup doesn’t stand a chance against acids, which break down the mineral. Another option is Sodium Bicarbonate (baking soda), which helps to release calcium deposits. 

Here are four options:

• White Vinegar: A household staple, vinegar is gentle but requires soaking for at least a few hours to remove stubborn buildup.

• CLR (Calcium, Lime, Rust Remover): A commercial product that’s stronger than vinegar. Soaking for a few hours or overnight is usually enough to clear away deposits.

• Baking Soda: This may be a gentler option for surfaces such as brushed nickel that may be damaged by acids. It is also easier to apply to the outer surface of your fixtures.

• Good ‘ol fashioned elbow grease: Usually, scrubbing is enough to take off stubborn calcium build-up on your fixtures. Try a little dish soap and a good microfiber towel.

  
  

Step 4: Soak and Scrub

For cleaners like vinegar or CLR, fill a bowl and let soak. 

• Put on rubber gloves and pour a small amount of the cleaning agent into a glass bowl.

• Gently place the clogged showerhead or aerator into the solution.*Remove any rubber seals before placing them into the solution.

• Check back in 4 - 8 hours. Use a soft brush to scrub away the deposits. If they don’t come off easily, let them soak overnight, or up to 24 hours.

Be careful to avoid splashing, especially near stainless steel sinks, as some acids can cause permanent stains if not rinsed immediately.

Step 5: Rinse, Reassemble, and Admire

After cleaning, give everything a good rinse to remove any lingering solution. Screw the cleaned parts back onto your faucet or shower head. And turn on the water to test your newly cleaned fixture.

Bonus Tip: Prevention is Key

Calcium buildup happens because of hard water, so consider installing a water softener or regularly cleaning your faucets to prevent buildup from getting out of control.

Also, we do not recommend using a stronger cleaner, such as muriatic acid or harsh abrasives, as these can cause damage to your sink or harm to yourself.

And after dealing with calcium buildup, take the next step toward a healthier home by improving your indoor air quality.
