Cleaning Silgranit granite sinks: what to look out for
Silgranit sinks are extremely hard and resistant. This means that looking after them is really very simple. Nevertheless, when cleaning a granite sink you should be aware of a few things in order to keep enjoying the fantastic look and feel for as long as possible. This care guide provides advice on how best to clean Silgranit, from daily care to deep cleaning and removing stains.
The advantages of a Silgranit sink
Silgranit PuraDur sinks from BLANCO represent the advancement of the classic granite sink. The special composite material is 80 % made from the hardest component of granite, making our sinks particularly resistant and scratch-proof. This makes it almost impossible for dirt to adhere to the surface.
The fantastic feel is another asset. Thanks to granite’s high density, silgranit sinks feel particularly smooth and soft. Silgranit sinks are extremely easy to look after, while the surface has anti-bacterial properties thanks to the hygiene protection formula. What’s more, the sinks are available in lots of different colours, with the material dyed right the way through. This means that slight kinks or staining foods will not cause any changes to the colour of your silgranit sink. Only limescale deposits many lead to discolouration, but these can be removed in next to no time.
BLANCO Silgranit sinks are the perfect combination of durability, easy care, smoothness, hygiene and design.

Daily care for your granite sink
To clean marks and everyday traces of use from your sink on a day-to-day basis, all you need is a sponge, some detergent and water. Slightly moisten the sponge under running water. Squeeze a small amount of detergent onto the soft side of the sponge. Clean your granite sink by rubbing it with the sponge in small, circular movements, using only the soft side of the sponge. Once you’re finished, rinse your sink thoroughly with clean water. Finally, rub your sink dry with a microfibre cloth in order to prevent limescale.
Removing metal abrasion
Silgranit sinks are extremely hard. As a result, using metal objects like pots can cause metal abrasion – dark streaks that are particularly noticeable on light surfaces. Removing them is easy. Again, put some detergent on a moistened sponge, this time using the rough side. Rub the sink with the rough side of the sponge, using circular movements, to remove the streaks. Rinse your sink down with clean water and rub all of the damp surfaces dry with a microfibre cloth.
Removing discolouration
If you go for a long time without cleaning your Silgranit sink, limescale particles will gather on the surface. These deposits typically gather around the mixer tap and on the drainer, as dishes dry here and water droplets evaporate. While the deposited limescale is easy to spot against dark sinks, it can easily go unnoticed at first on light-coloured sinks. Only when the limescale becomes discoloured, for instance if the once-white limescale becomes the colour of a tea bag, does it become apparent. Silgranit itself is completely colour-fast – it is the limescale deposits that become discoloured. Using BLANCO Activ powder can help. This dissolves the layer of limescale and dirt and restores the sink to its original colour.
Monthly deep-cleaning
It is best to clean your Silgranit sink every day, as described above, in order to prevent limescale from forming. This will help prevent discolouration, which is harder to remove. In addition, you should also give your BLANCO sink a basic deep clean every couple of months in case limescale has formed despite these efforts. The easiest way to do this is with BLANCO Antikalk. The formula, which has been specially developed for BLANCO mixer taps and sinks, cleans gently yet effectively. Spray the surface of your Silgranit sink sparingly and let BLANCO Antikalk take effect for five minutes. Then clean your granite sink with a sponge to remove any limescale residue that has now been loosened. At the end, rinse your sink down with clean water and rub the surface dry with a microfibre cloth.
If any limescale or stubborn discolouration is still visible after this first clean, use a heavy-duty detergent or BLANCO Activ powder in a second step. Specially adapted to Silgranit PuraDur, this powder loosens any stubborn dirt from your sink.
Using it is easy. First close the outflow on your sink. Open the little sachet of powder and scatter the contents evenly around the sink bowl. Now fill your bowl with water at a temperature of at least 60 °C. Ideally, use water boiled in the kettle. Use a small measuring cup to scoop some of the solution out of the bowl and pour it over the drainer, too. Leave the BLANCO Activ powder to work for at least two hours.
Even better: prepare the mixture in the evening after you have used the bowl for the last time that day, and leave the solution to work overnight. After the time is up, drain the solution away. Rinse your sink down with clean water and rub all the damp surfaces dry with a microfibre cloth.
Note: if you’re looking to get rid of stubborn dirt, avoid using alkaline agents or drain cleaners. These substances are so aggressive that they may even attack hard, resistant granite surfaces.
