What’s more, the material is highly resistant. You want to have free rein in your kitchen, whether you're cooking with tomatoes, strawberries, lemon juice or carrots.

Sometimes, things can really hot up in your kitchen. Your Silgranit sink is happy to go with the flow. After all, Silgranit is heat-resistant up to 280 °C, so you can put hot pots and pans straight into the sink without any qualms. It can keep its cool and take the heat.

Silgranit consists of 80 % granite. In practice, this means no scratches, no cracks, and no fractures. In short: your sink is extremely resistant. As such, you won’t need to worry about putting pots, pans and plates down wherever you fancy in your kitchen. You can also splash red wine, orange juice, hot coffee or beetroot juice around with abandon. We guarantee that your Silgranit granite sink won’t mind one bit.

Being in the kitchen is all about living, eating and enjoyment. Oil might splash onto the stacker or the odd bit of meat might end up in the sink bowl every now and then. This is nothing to worry about. Your Silgranit sink is happy to go with the flow. Silgranit has a defensive shield to protect you and your food from dirt and bacteria. This is down to its unique, patented hygiene protection formula, which has an antibacterial effect. This is scientifically proven: tests show that this hygiene protection reduced the build-up of the relevant bacteria by up to 98 %. This makes chopping, cooking and eating in your kitchen hygienically safe.

Cutting up beetroot, chopping onions or peeling apples: things sometimes go astray when you're performing kitchen tasks. But your Silgranit sink is perfectly able to cope. Its secret is its fine-pored, unbroken surface, which practically prevents dirt from sticking at all and ensures that water simply rolls away. This protects the sink from limescale deposits and contamination. However, if the odd stain does appear at any point, simply reach for a scouring pad and a little washing-up liquid and water. You’ll have your Silgranit sink clean again in one wipe. In case of stubborn soiling, it’s best to use a professional cleaning agent, such as our BLANCO AKTIV powder.

Fresh fruit, vegetables and years of bright sunshine provide the surfaces of your sink with plenty of challenges as time goes on. But they remain completely indifferent. After all, our Silgranit sinks are solid as a rock. Unflagging. The material is hewn from a single piece of granite, so it will not discolour or fade under normal use, and with a little care.

Our Silgranit sinks can normally withstand hot pans at up to 140 degrees and very hard water. However, if you were to slide a pot across the drainer, for instance, it could cause abrasion. This is because Silgranit has a fine-pored surface that is harder than metal, thus leading to dark marks on light sinks. However, this is no cause for concern. You can simply clean your sink with a sponge and a little washing-up liquid and hot water. Once again, it will be the kitchen gem that you know and love.

Robust and colour-fast: these qualities define your Silgranit sink. This makes any little dark streaks that appear on your surfaces all the more striking. These are most likely to have been caused by pots. But there’s no need to panic: you can remove such signs of abrasion in one step: After all, not only is your sink robust, but it is also extremely easy to clean. Just use the rough side of your sponge, moisten it with a little hot water, and wipe it over the dirty area. Voilà! Your sink will be its shining self once again.

Day-to-day use of your Silgranit sink may result in the odd mark appearing. If limescale deposits have formed on your sink, for instance, these can easily absorb spilled coffee, tea or red wine. You may see notice slight discolouration as a result. However, if you look after your sink regularly, this won’t be a problem. You won’t need to embark on a deep clean to put it right. After all, as materials go, Silgranit is extremely easy to clean. A little bit of TLC with a scouring pad and some washing-up liquid is all your sink needs for marks to disappear in a few simple steps. Then it only remains to rinse it down with water and rub it dry, and your sink will be sparkling clean once again.

Limescale can be a persistent problem, depending on where you live and the state of your water pipes. Unsightly water marks can appear all of a sudden and detract from the beauty of the pride of your kitchen. It’s just as well this that cleaning your Silgranit sink is no big deal. To put it right, you need a professional descaling agent, a commercially available heavy-duty detergent or vinegar concentrate, along with hot water no cooler than 60 °C. Apply the solution to the marks and leave it to steep for at least 2 hours (or simply overnight). Then wash the sink down thoroughly, clean it with a sponge and finally rub it dry.

We do our bit to make sure that you’re all set up, so our stainless steel and ceramic sinks come with a punched-out tap hole. This means that you won’t have to do any extra work before installing it. Silgranit sinks are milled from the underside. You simply have to knock through the pre-milled holes. How to do it: first place the sink in a sturdy holder. Now take a punch and place it in the middle of the mark. Use a hammer to hit the punch holes for the mixer tap, soap dispenser and drain remote control, as required, without exerting force on the punch itself. Then carefully knock the rest of the Silgranit pieces out of their marked holes. Now get a file and file the hole to the right size. You may need to do this if the hole is flush with the preliminary milling. Now there’s only one thing left to do: insert your mixer tap, and off you go.

Milky patches can soon show up on your stylish dark sink. These are caused by limescale deposits, which can vary hugely from place to place, and depending on the state of your water pipes. Such stains also pick up deposits from substances like tea or coffee, and are thus responsible for discolouration. But all this isn’t as bad as it sounds. Luckily, BLANCO ANTIKALK, a little vinegar-based cleaner or diluted citric acid and hot water can come to your rescue. The limescale will dissolve if you clean your kitchen sink thoroughly with these substances. If you don’t want to constantly have to contend with unsightly marks, be sure to dry your sink off with a microfibre cloth after every use. Doing this will prevent the limescale from occurring in the first place.

The basket strainer in the secret hero in your sink. After all, it prevents your sink from getting clogged up, thus ensuring perfect functionality. Over time, however, the basket strainer will collect some dirt, so you should give it a clean every now and then. You don’t even have to buy a special cleaner for that purpose. Here’s our trick: put a level teaspoon of powdered dishwashing detergent onto the closed basket strainer. Pour approx. 250 ml boiling water over it and leave the solution to work. Now brush and scrub it (e.g. with a dishwashing brush) until the basket strainer and drain cup are shining once again. Finally, open up the basket strainer and take out the basket insert. Now you have room to clean the hole opening in the drain cup. Once this is squeaky clean too, reinsert the basket insert and rinse it with clean water.
