Hard water stains are known by many names – limescale, mineral deposits, mineral buildup, hard water deposits – but the meaning is the same. Hard water stains appear as chalky white residue that results from buildup of excess minerals present in hard water.
Limescale is the all too familiar by-product of hard water. A hard, chalky deposit which bonds on surfaces when hard water comes into contact. Limescale will usually appear yellowy white in colour but this can vary, water with a higher iron content will have a reddish brown deposit.
Limescale is a hard, white substance that appears rather chalky. Usually, you'll spot limescale around more watery appliances, such as: Sinks. Taps.
Does CLR get rid of hard water stains? Yes, for stubborn hard water stains on shower walls and tiles, bathtubs, sinks or faucets that need more scrubbing power, you may have to use something stronger than vinegar, like CLR Brilliant Bath Cleaner, a top-tested product that won a 2020 Good Housekeeping Cleaning Award.
DO not use CLR on natural stone or marble, terrazzo, colored grout, painted or metallic glazed surfaces, plastic laminates, Formica, aluminum, steam irons, leaded crystal, refinished tubs or any damaged or cracked surface. CLR may etch older sinks, tubs and tiles. CLR is corrosive.
Grab a spray bottle and mix equal parts water and vinegar (you can also add a teaspoon of Dawn dish soap for more clinging power). Spray the solution on the bathtub stains, let it sit for at least 15 minutes, then wipe clean. Let the solution sit longer depending on the severity of the stains.
For a tried and true cleaner to tackle hard water stains, we recommend Bio-Clean Hard Water Stain Remover. It's easy to use, efficient, and it smells pleasant, too. For a more budget-friendly but still effective pick, check out CLR Multi-Use Calcium, Lime & Rust Remover.

How do professionals clean showers? Professionals use acid-based cleaning solutions like vinegar for hard water spots and soap scum. For deep-set soap scum, cleaners will use heavy-duty detergents and degreasers. Bleach cleaning solutions are best reserved for cleaning the mold and mildew from grout.
Baking Soda and Hydrogen Peroxide
Create a paste that is one part hydrogen peroxide to two parts baking soda. Apply the paste and allow it to work its magic for at least 30 minutes. Now scrub with a sponge or nylon brush and rinse with warm water. This works wonders on red or black stains.
For really tough hard water stains, try scrubbing with some hydrogen peroxide. Yep, the same stuff you have in your first aid kit. Hydrogen peroxide plus some elbow grease should banish even the most stubborn of hard water spots from your metal fixtures.
Does Epsom Salt Really Clean Hard Water Stains? In short, yes. Epsom salt works best with baking soda and water and can remove even the most stubborn of hard water stains from your bathroom.

Regular glass cleaner won't help at all. We tried both Windex-style ammonia-based window cleaner, and also vinegar-based auto glass cleaner and found that neither has any effect on the stains.
“Vinegar is a good cleaner because it's acidic, but when you add dishwashing liquid/dish soap to it (which is a base or neutral) - you neutralise the vinegar. You take away the very thing that makes it work well. “The dishwashing liquid works that well on its own. Adding the vinegar is a pointless step.”
Removing Hard Water Deposits From Faucets
Use vinegar to help loosen the hard water film and buildup before scrubbing. Soak a clean rag in vinegar and drape it over the faucet, making sure there is direct contact with all of the hard water deposits. Let the rag sit for at least 30 minutes; an hour is better.
A paste of baking soda and hydrogen peroxide cuts through soap scum and hard water stains on tubs and tiles.
