Granite is the symbol of durability and natural power and has secured a permanent place in kitchens around the world. Its robust elegance and almost indestructible surface make granite the ultimate material for sinks that are used intensively every day. Natural stone sinks like these are not only a visual highlight, but also a practical addition to any kitchen. Their unique grain and variety of colors fit seamlessly into individual design concepts and at the same time offer a durable work surface for all types of kitchen work.

However, granite must be cleaned and requires regular care. The following guide will show you how to ensure that your granite sink looks like new even after years.

Why do granite sinks require proper care?

Without proper care, limescale, soap residue and other deposits can build up in the pores, making the sink appear dull and stained . Furthermore, aggressive cleaning agents can attack the sealed surface and permanently damage the material. It is therefore important to use cleaning and care products that have been specially developed for the needs of granite.

Treating a granite sink should not only ensure a clean appearance , but also ensure that the quality and beauty of the material is maintained . With regular and careful care, your granite sink will be a long-lasting companion that combines functionality and aesthetics in your kitchen.

Which household remedies and cleaning products are suitable for the care of granite?

When cleaning and caring for granite sinks, choosing the right product is crucial to ensure the durability and beauty of the material. Home remedies offer a gentle and natural alternative to chemical cleaners . A popular option is a mixture of warm water and mild soap, which is effective and gentle at the same time. For perfect disinfection, a solution of water and alcohol ( isopropanol ) in a ratio of 50:50 can be used , which is then rinsed off with clean water and rubbed dry after application.

In addition to household remedies, there are also professional products such as the natural stone worktop cleaner from Emma Grün , which have been specially developed for the care of granite surfaces. These are pH-neutral and you will not find any acids, alkalis or abrasive additives that could damage the stone. On top of that, they not only offer effective cleaning, but often contain ingredients that refresh the shine of the granite and care for the surface to perfection.

Emma Grün Tip: Regardless of whether you choose home remedies or professional cleaning products, it is important that the products are safe for granite sinks and do not contain any substances that could attack the stone or weaken the sealed surface.

Cleaning & maintaining granite sinks: Dos & Don'ts

Granite is an extremely robust natural rock that comes from a deep geological formation. It forms from the slow cooling of magma beneath the Earth's surface, resulting in a coarse-grained structure rich in minerals such as quartz, feldspar and mica. This composition gives granite not only a unique and diverse grain with a spectrum of colors, but also an impressive hardness and density. Granite resists scratches better than most other materials, withstands high temperatures and shows good resistance to many chemicals .

However, granite is not completely immune to staining or acid damage , which is why proper treatment is essential to preserve the natural beauty and functionality of the stone. However, to ensure that you can enjoy your granite sink for years to come, there are a few things to keep in mind when caring for it. The following dos and don'ts reflect this.

Dos: How to keep your granite sink functional and an eye-catcher

  • Always use soft cleaning tools such as microfiber cloths or sponges.
  • Neutral cleaners or special granite cleaners help to preserve the surface seal.
  • To avoid limescale deposits, natural stone sinks should be dried thoroughly after each use. A light polish with a special granite care product can preserve the shine and protect the surface.

Don'ts: What you should avoid when cleaning and caring for granite

  • Avoid using acidic cleaners such as vinegar or lemon juice, which can attack the sealed surface.
  • Abrasive cleaners and scratchy sponges are taboo as they can leave scratches.

Emma Grün Tip: When caring for granite surfaces, remember that regularity is the key to longevity and a beautiful appearance. Daily cleaning prevents deposits from forming, which can lead to longer cleaning times and, in the worst case, damage to the material. With this simple routine, your granite sink will not only stay clean, but also protected and retain its natural shine for years to come.

Protect granite sinks in the long term: How to protect natural stone from external influences

The long-term quality and protection of your granite sink is essential to maintaining its beauty and functionality. The following tips will show you how to get the most out of your investment and care for your granite sinks:

  • Seal regularly: Granite is naturally porous, so it is crucial to seal it regularly. This protects the surface from water and oil, which could otherwise penetrate the stone and leave stains. It is recommended that granite sinks be sealed at least once a year . Sealing may be required more frequently with increased use.

  • Avoid heat: Do not place hot pots or pans directly on your granite sink. Although granite is heat resistant, extreme heat can still cause cracks or damage the seal . To prevent this and protect the surface, we recommend that you always use a coaster or mat as a base.
  • Choose cleaning products carefully: Use gentle, pH-neutral products for daily cleaning. Avoid harsh chemicals, abrasives or acidic cleaners that could attack the seal and dull the granite.
  • Prevent water stains: To prevent the formation of water stains, you should dry your granite sink after each use. This is because particularly hard water can leave visible residues, especially on dark granite .
  • Pay attention to food safety: When you clean your granite sink, you must ensure that all cleaning and care products are food safe . This is because they come into contact with surfaces on which food is prepared and questionable ingredients that can harm your health have no place. This is precisely why we recommend that you use sustainable products such as the natural stone worktop cleaner from Emma Grün for cleaning and care. This is precisely when you don't have to worry about any health risks.

By following the tips mentioned and regularly caring for your granite sink, you can ensure that it remains a highlight of your kitchen for years to come.
