Vanquish limescale, avoid damage: Here’s how

Incorrect cleaning methods and products can damage your shower head. This is not covered by the warranty, so please follow the recommendations below.

The right cleaning tools:

  • Always use a soft, clean cloth and never abrasive materials such as scrub sponges or microfiber cloths.
  • Don’t use steam cleaners because high temperatures can damage the shower.

The right cleaning product:

  • Only use gentle cleaning products, for example ones containing citric acid.
  • Do not use any cleaning products containing hydrochloric acid, formic acid, chlorine bleach or acetic acid, as they may cause significant damage. Cleaners containing phosphoric acid can only be used to a certain extent. Never mix cleaning products!
  • Never spray cleaning products directly on showers because the spray mist can penetrate into the shower and cause damage.
  • It’s best to spray the cleaning product on a soft cloth and then use it to wipe the surfaces.
  • After cleaning, rinse your shower thoroughly with clear water and rinse the shower through completely.

Regular cleaning: 

In addition to choosing the right cleaning products and tools, how often you descale your shower head plays a key role in its care. The frequency very much depends on the water hardness in your local area. Cleaning needs to be more regular in areas where the lime content is higher. One of the early signs of limescale buildup is when the water sprays no longer exit the nozzles cleanly.

Why is limescale on the shower head a problem?

Limescale deposits on shower heads should not be underestimated, as they present various difficulties. Firstly, too much limescale can negatively impact the water flow, which leads to uneven water or water spurting everywhere. Not only is this annoying, but it can reduce the efficiency of your shower. Limescale deposits also cause an aesthetic problem: They are unsightly and can quickly put your carefully designed bathroom in the wrong light.

Another, often overlooked, aspect is hygiene. Bacteria and germs find it easier to breed on the uneven surfaces of limescale deposits. This negatively impacts the cleanliness of your faucets and poses a health risk.

What causes limescale on the shower head and faucet?

To effectively crack down on limescale deposits, it is important to start by understanding how they are caused. Hard water with high lime content is mainly found in regions with limestone or sandstone. The lime comes away from the stone, and the water transports it into the plumbing system. The water hardness is usually measured in °dH, or degrees of hardness. If water now flows through the faucets and is heated or evaporated, these minerals get left behind. Over time, they form the typical white, crusty deposits we call limescale. The rule of thumb here: The harder the water, the faster the limescale buildup on the faucet and shower. 

How temperature influences limescale formation

Increased limescale buildup at higher temperatures: Calcium ions dissolve easier in cold water. When the water is heated, this solubility decreases. This means when water is heated, the dissolved minerals do not remain in the water vapor, forming limescale deposits instead.

Accelerated evaporation: Warm water evaporates faster than cold water. In this process, the dissolved minerals get left behind and form limescale deposits, particularly in places where water is regularly heated and evaporated, for example kitchens and bathrooms.

With this in mind, you are welcome to loosen up your faucet by running “cooler” water with CoolStart technology, which will also save energy. CoolStart faucets allow only cold water to flow when the handle is in the middle position, whereas standard faucets in the middle position immediately dispense mixed water, thus consuming energy. The result: CoolStart helps you to reduce your CO2e emissions, while also reducing your energy costs in the long term.

Signs of limescale in shower heads and faucets 

No matter how close you look when in the bathroom, limescale can go undiscovered for quite a long time. But there are a few typical signs that your shower head or faucet is suffering from limescale deposits and it’s time to quickly clear them out of your shower.

  • Reduced water pressure: One of the early signs of limescale deposits is a significantly reduced water flow. This happens when limescale has built up in the faucet’s nozzles, narrowing the channel the water can flow through. This ends up causing a weaker or uneven water spray.
  • Spurting or uneven water: If the water spurts out of your shower head or is in an uneven pattern instead of an even flow, this could be a sign of limescale deposits in the nozzles.
  • White or greenish deposits: White or greenish deposits around the faucet’s aerator are often visible signs of limescale. These deposits can also appear at the base or other parts of the faucet as well as on the shower head.
  • The faucet becomes hard to use: Limescale can also take hold in the faucet’s mechanisms, which can make the faucet hard to use or the handles and buttons feel stiff.
  • Noises when the water flows: Sometimes, too much limescale in faucets can cause unusual sounds, such as cracking or whistling, especially when turning the faucet on or off.

Frequently asked questions about descaling the shower head

What are effective ways to remove limescale deposits from my shower head?

For mild limescale issues, our QuickClean technology offers an efficient solution to tackle annoying limescale deposits. This technology is integrated into our shower heads and features flexible silicone nozzles on the jets. Simply rubbing the nozzles with your fingers removes limescale and dirt – it couldn’t be easier. More severe limescale deposits on the shower head can be removed using citric acid. Spray the cleaner on a cotton cloth and carefully wipe the faucet clean. Or place the shower head in a quick water bath containing citric acid, then thoroughly clean the shower using fresh water.

How often should I descale my shower head?

How often you descale your bathroom products depends on the water hardness in your area. If the lime content is high, more frequent cleaning is recommended. Be sure to also look out for the potential signs of limescale so that you can take action in good time.

Can I take measures to prevent limescale deposits?

Regularly wiping the faucets after use can prevent limescale deposits. Setting a lower temperature on the hot water tank also helps. Or you can use hansgrohe CoolStart technology and minimize energy costs while you’re at it. If you live in a hard water area, we highly recommend installing a water softener system.

Can limescale influence my shower head’s water flow?

Yes. Limescale deposits can have a negative impact on the water flow because they clog the openings in the jets. This leads to a weaker and uneven water spray. Regular descaling helps to keep the flow of water constant and ensure the faucet is working properly.
