How do I take care of a Blanco stainless steel sink?
For normal cleaning, we recommend regular dishwashing detergent. After cleaning, rinse the sink with warm water and dry it. We recommend cleaning the sink once a month with Blanco DeepClean stainless steel cleaner and care product.
- Daily cleaning with regular dishwashing detergent or DailyClean+.
- If necessary, cleaning and polishing with Blanco DeepClean stainless steel cleaner and care product.
- Thorough cleaning with Blanco DeepClean:
- Apply Blanco DeepClean to a damp cloth or sponge
- Scrub the sink clean in the direction of the brushing
- Rinse and wipe off water drops, moving the sponge along the brushed surface
- Finally, dry the sink with a dry cloth
The sink surface will become clean and shiny. If dirt remains, repeat the cleaning as described above. The corners of sharp-edged sinks are best cleaned with Blanco DeepClean and a small brush.
Note: For Durinox sinks, cleaning with a damp sponge or microfiber cloth and a small amount of dishwashing detergent is sufficient. Blanco DeepClean stainless steel cleaner and care product is not needed for polishing.

How do I care for and clean the plastic parts of Blanco sinks?
Plastic parts available as standard or optional accessories for Blanco sinks, such as a vegetable bowl, should be cleaned by hand with regular dishwashing detergent. Plastic parts must not be washed in the dishwasher. For many sink models, the same parts are also available in stainless steel.
How do I care for a Silgranit/composite sink?
Rinse the sink immediately after pouring staining substances (such as tea or coffee) to avoid lime deposits. If lime remains on the surface, dirt will attach to it over time. Use normal dishwashing detergent for cleaning.
Marks from metal objects (e.g. frying pans) can be removed with a sponge moistened with dishwashing detergent or cooking oil, using circular motions.
Recommended care and cleaning agents for Silgranit/composite sinks:
- Daily cleaning: Use dishwashing detergent to avoid stains. Rinse and dry the sink after use. Stains and marks should be removed immediately, for example with Blanco DailyClean+ cleaner.
- Thorough cleaning:
- Spray Blanco DailyClean+ cleaner onto the surface and let it act briefly.
- Rinse and wipe with a microfiber cloth. Repeat if necessary.
- Then apply Silgranit DeepClean with a damp sponge, using circular motions.
- Let it act for approx. 5 minutes, rinse with clean water and dry with a microfiber cloth.

How do I care for a ceramic stone sink?
For daily cleaning, warm water, a cloth and a little detergent are sufficient. Stubborn stains should be removed immediately. We recommend Blanco DeepClean Ceramic cleaner, which dissolves grease and limescale, removes metal marks, and polishes and protects the surface.
DeepClean Ceramic is also suitable for polished or satin-finished stainless steel sinks and ceramic hobs.
Avoid dragging sharp-edged objects or knives across the ceramic surface to prevent scratches. Dropped sharp objects may damage the surface.
Proper care extends the service life of the sink and preserves its appearance.

Silgranit sinks:
Fresh fruits, vegetables and years of bright sunshine present challenges to kitchen sink surfaces over time. Despite this, the Silgranit sink made of stone material is long-lasting and withstands these challenges quite well. If treated according to the care instructions, the color of the material of Silgranit sinks is maintained well even during long-term use.
The advantages of Silgranit material: resistant to wear, heat, and common substances used in the kitchen, this keeps the BLANCO basin beautiful despite daily kitchen use.
As with all sink materials, Silgranit sinks also show signs of wear and tear during normal use, and their surface may change over time. In particular, hard dishes such as pots and pans may change the surface of the sink over time, even if the surface of the Silgranit sink shows signs of wear, it does not affect the use value of the sink.
Stainless steel – sinks:
Colored stainless steel basins are made with the PVD coating method. PVD-coated stainless steel basins have the same properties as stainless steel basins. They withstand normal use and wear and tear, but heavy objects such as cast iron pans and large pots should be handled with care at the bottom of the sink. When sliding on the surface of the sink, heavy and rough objects scratch the surface of all stainless steel sinks.
The formation of marks and wear of the color is part of the normal wear and tear that occurs when using the sink.
Do not use sponges with roughened surfaces (magic sponge or PataPata) for cleaning, these can scratch the sink coating.
By using the bottom grid designed for the bottom of the sink, you prevent scratches on the bottom of the sink, in addition, the bottom grid makes it easier to clean the dishes and speeds up the drying of the dishes.
The bottom grid is available as an accessory from Lapetek's WebShop.
What causes the grooves/jaggedness on the bottom (bottom/outside) of the Silgranit sink?
Posted: helmi 8, 2024

Sinks
The patterns on the bottom of the Silgranit sink vary a lot due to the manufacturing technology. The visible side of the sink in use is against the mold and is smooth, as it should be. The "bottom" of the sink is facing up in the mold and during the curing process the ingredients in it form different patterns and grooves; sometimes even more visible. The bottom surface has no effect on the sink's durability or the sink's warranty, but is a normal feature related to the manufacturing process.

Sinks
The sink is attached to the countertop with the brackets that come with the sink and sealed with sanitary silicone.
The inner edges of the sink opening to the laminate surface must be protected from moisture by applying sanitary silicone to the cut.
Adhesive sealing compounds must not be placed between the basin and the counter, so that the basin can be removed, if necessary, without damaging the countertop.
Can a manual trash filter be converted to a remote control model

Sinks
In most models this is possible. In this case, you should order a separate remote control set, which includes the remote control knob, cable, waste basket and the cup part of the remote control bottom valve. These parts are replaced by standard parts in the sink.
Can the remote control model be changed to a manual one ?

Sinks
You can change the remote control model to a manual by removing the remote control cable and knob and by buying a manual waste basket suitable for the sink and, if necessary, a bottom valve part.
Should the sink have a CE mark?

Sinks
There is a harmonized product standard for kitchen sinks, so they must be equipped with the CE mark. The CE marking indicates that the product has been tested with a test method according to the harmonized product standard and that the product complies with the declared performance level. A declaration of performance (Declaration of Performance = DoP) is a prerequisite for affixing the CE mark. You can download the performance declarations of the sinks from each sink’s product page under the section "downloadable files."

The waste basket in the sink has disappeared. How can I get a new one?

Sinks
Waste baskets can be ordered from our spare parts store. Since the waste basket of different sinks are different and of different sizes, take a close look at your current model and compare it with the picture in the WebShop. The waste basket in the picture should be exactly the same as the one you have. You can find them in our online store with the search term "roskasihti". If you are not completely sure that you recognize the correct trash filter model, take a photo of the type of the plate at the bottom of the sink and attach the photo to our customer service along with the Care message, so that the correct trash filter can be determined.
If you can't find a completely similar product, the waste basket you have is no longer available.
Why doesn't the water drain properly from the stainless steel sink?
Posted: syys 26, 2025

Sinks
The position of the work surface and the basin must be horizontal, so that the water flows from all directions of the basin towards the bottom valve. If the counter top and the sink are not horizontal, water may flow to the edge/corner of the sink, in which case the position of the counter and the sink should be checked and adjusted directly.
If the water does not drain properly, it is possible that the surface of the sink is so dirty that lime or other dirt stuck to it prevents the water from draining properly.
Clean the sink completely shiny with Blanco DailyClean and DeepClean cleaning agent and you will notice how the water runs off the surface of the sink. You can find cleaning products and their instructions for use, as well as the product pages for cleaners for different materials, here.
Why does the bottom valve remote control not open or close the bottom plug properly?
Posted: syys 26, 2025

Sinks
Infino models:
Below the waste basket (1) there is a plug (2), the lower part of which has a pin (3), the length of which should be adjusted to the correct length. If the bottom plug does not open properly, the pin is turned counterclockwise (longer). If, on the other hand, the bottom plug does not close properly, the pin is turned clockwise. In the open position, the water must flow out, and in the closed position, the waste basket acts as a plug. If the water does not run properly out of the sink, the pin (3) is too short, and correspondingly, if the water does not stay in the sink, the pin (3) is too long. Adjust the length of the screw to the correct length and check that the remote control of the waste basket works perfectly.
Traditional models:
The waste basket has a pin (1) below it, the length of which should be adjusted to the correct length. The adjustment is done by turning the bottom plug pin (2) counterclockwise until you can lengthen/shorten the screw (3). In the open position, the water must flow out, and in the closed position, the waste basket acts as a plug. If the water does not run properly out of the sink, the pin (3) is too short, and correspondingly, if the water does not stay in the sink, the pin (3) is too long. Adjust the length of the screw to the correct length and check that the remote control of the waste basket works perfectly.
Why there is light stains in my sink?
Posted: syys 26, 2025

Sinks
The lime content of tap water varies from place to place and its adhesion to the surface of the sink can be seen as pale stains. Stains are often in places where water can "stand" after water has been poured into the sink. When the water dries up, lime remains on the surface, which collects dirt. Lime accumulates with dirt in layers, regardless of the sink material and the color of the sink, cleaning the sink from several layers of dirt requires several cleaning sessions. The sink should always be cleaned after use, before layers of dirt and lime have time to accumulate and harden on the surface of the sink.
Lime on the surface of the sink should be cleaned with Blanco DailyClean cleaning agent.
If there is a lime deposit on the surface of the sink, all the dirt sticks to it more easily than to a clean sink.
The cleaning agent can be ordered from Lapetek's WebShop.

What causes the rust spots on the surface of the stainless steel sink? How do I remove them?
Posted: syys 26, 2025

Sinks
Rust spots visible on the surface of a stainless steel sink are caused by metal particles that have come, for example, from the plumbing or tools. These metal particles adhere to the sink surface and rust relatively quickly, appearing as rust spots on the sink.
To avoid unnecessary scratches, the metal particles should first be removed using non-abrasive cleaning agents. Once all the spots have been removed, the sink should be rinsed and dried thoroughly and left to dry overnight.
If the rust spots have been in the sink for a longer period of time and do not come off during cleaning, their removal may require more intensive cleaning. Vinegar or citric acid can be used if necessary.
It is important that all rust spots are completely removed. Note that using steel wool or similar products (such as a magic sponge) will leave scratches on the sink surface. However, cleaning will not impair the functionality of the stainless steel sink, even if scratches remain on the surface. After cleaning, the sink should be rinsed very thoroughly, dried, and left to dry overnight.
For thorough cleaning of the sink, we recommend using BLANCO DeepClean RST cleaner. In addition to cleaning, DeepClean RST also polishes the sink surface. Order DeepClean RST cleaner here .
Since rust spots are caused by external factors and the general properties of stainless steel, rust spots on the sink surface are not covered by the product warranty.
