How to Remove Calcium Buildup

Tap water contains minerals such as calcium and magnesium. When it evaporates, these minerals are left behind, leading to chalky white stains on faucets, shower screens, and even glassware.

While calcium buildup and staining occur in all homes, these problems are more common in areas with hard water, and Arizona's water is especially hard. In fact, Phoenix consistently ranks among the cities with the hardest water in the nation due to its water supply flowing over limestone and other mineral-rich rocks.

Over time, as hard water dries on your home's fixtures and surfaces, you end up with:

• White stains on taps and showerheads
• Cloudiness on countertops and sinks
• Stubborn marks on tiles

Buildup inside pipes can reduce water pressure, and an accumulation of minerals inside appliances such as dishwashers and water heaters can lower their efficiency.

Once minerals from hard water bind to a surface, they adhere strongly, making staining difficult to remove. Even soap and scrubbing aren't very effective.

So, how do you remove calcium buildup? The key is to take advantage of chemistry by using an acidic cleaner. These cleaners convert solid minerals into more water-soluble salts, allowing the buildup to be rinsed off surfaces.

The best cleaning agents for calcium buildup include:

• Vinegar and lemon juice. These gentle acids break down calcium buildup while being safe for many fixtures and household surfaces.
• Commercial descalers. Typically made with stronger or more concentrated acids, commercial descalers like CLR work on tougher stains and can be used in some appliances.

Soaking and scrubbing with a soft brush help with the most stubborn stains. However, mineral stains return quickly. If you have hard water and want to minimize cleaning, the best solution is to invest in a water softener.

Wondering how to get rid of calcium deposits and keep them away? Unfortunately, these kinds of stains come back quickly on fixtures and surfaces frequently exposed to running water. However, you can minimize future staining by:

• Wiping down shower glass and other surfaces after use
• Filtering the water you add to coffee machines and other kitchen appliances
• Running descaler through your appliances every few months
• Scheduling professional maintenance for your plumbing and HVAC systems
• Installing a water softener to remove minerals before they reach your fixtures

Stains on surfaces and fixtures can usually be removed with simple DIY methods, but mineral buildup inside pipes are best left to professional plumbers. You might need professional descaling if you notice:

• Low shower water pressure

• Clogged pipes or lots of chalky residue coming out of your faucets

• Water heaters not working efficiently

• Noticeable corrosion on pipes or faucets

A professional will examine your whole home to determine the extent of your hard water issues before recommending the right solution.
