You can use Mr. Clean Magic Eraser, then thoroughly rinse with dish soap and water. You can then apply mineral oil on the sink once dry to bring back its dark sheen.
Mineral oil applied with a damp cloth can also be used to restore the luster. We do not recommend using BLANCOCLEAN on dark colored Silgranit II sinks. MISCELLANEOUS: To remove Calcium Deposits (a white ring around the bottom of your sink), use Lime Away or CLR cleaner.
Prepare Your Cleaning Material
The prepared materials include white distilled vinegar, baking soda, mineral oil, and a cloth to clean your granite composite sink. The vinegar and baking soda reaction will create a foaming agent that will clean the grime off of the sink.
Once your granite composite sink is cleaned, you can restore its shine using mineral oil. Apply a tablespoon of mineral oil to a soft cloth and buff using a circular motion. Wait 1 minute, wipe away and enjoy the luster.

For everyday dirt and grime, we recommend cleaning your ceramic/fireclay sink with mild dish soap or detergent with warm water and a soft cloth.
CLEANING of GRANITE COMPOSITE SINKS
Generic stains should be removed immediately. Cleaning powders and creams which are even slightly abrasive should not be used, nor chemically aggressive detergents.
Applying a light layer of food grade mineral oil will add a protective repellent layer to your sink - simply leave the oil on the surface for 45 minutes then buff with a cloth. Repeat the process if needed. With a granite composite sink, prevention of stain and limescale build up is key.
Oil and Water Don't Mix
While federal regulations are in place to prevent dumping petroleum oil or products with mineral oil down the drain, few regulations enforce oil and grease discharge from restaurants. Instead, it's up to cities and municipalities to prevent this problem from occurring.
Once done, apply mineral oil (or baby oil or olive oil) to the entire sink surface. Using mineral oil regularly on the sink surface will prevent hard water and mineral deposits from building up on the sink surface.
Don't worry if the mineral oil leaves a mark. Even if your counters need to be sealed, the dark spot from the mineral oil will evaporate in about 30 minutes.
This type of sink is easy to clean
Using a non-abrasive cleaner will keep it clean. Taking care of it properly will preserve its color for many years. Keeping it clean is also important. You can use a magic eraser sponge to remove stains and a 50/50 water-bleach solution for cleaning.
Scratch and Stain Resistant
Blanco Silgranit sinks are scratch and stain-resistant. This may not sound like the biggest deal ever, but imagine paying a lot of money for a beautiful sink and finding a large gash in it days after installation because one of your family members put their dishes in the sink haphazardly.
While composite sinks are quite resistant to stains and scratches, it's important to note that they can be damaged by harsh chemicals and abrasive scrubbing devices.
Stubborn Stains – A solution of 50% bleach, 50% water should only be used for tough, stubborn stains. Let the solution sit in the bottom of the sink for one hour; then scrub. Rinse well. Also, the use of Bar Keepers Friend (directions included on bottle) will help remove stubborn stains.
Composite Granite Sink Disadvantages
Hardness: While some sink materials are more forgiving, composite granite is hard enough to break glassware when dropped onto the surface. This granite composite sink problem is something to consider if you frequently wash breakable dishes in the sink.
Yes, composite sinks can withstand boiling water. There is no issue with pouring hot water down a granite, quartz, or solid surface sink.
As with all types of sinks, granite composite kitchen sinks are heat resistant. However, they are not heat-proof, and cannot withstand extreme temperatures such as a hot pan taken off the hob and placed directly into the sink. The acrylic resin in the mix of a granite composite sink could warp or melt.
It is essential you avoid extreme variations in temperatures coming into contact with your sink – such as pouring out a pan of boiling water followed by ice cold water. This can cause thermal shock in composite sinks and will result in hairline cracks appearing.
Use vinegar cleaner, citric acid or rely on our BLANCO DailyClean+ cleaner to remove limescale deposits. Apply the cleaner to the affected surfaces and let it soak in. Then clean your sink with a soft sponge and finally rinse with clear water. Rub dry with a microfiber cloth and your sink is clean again.
The Blanco Anthracite sink is made from 80% granite and is practically built to last a lifetime. It effortlessly resists stains, chips, and general wear and tears like no other. Being heat resistant, the Blanco Anthracite sink can withstand heat up to 536 F, so it's safe to put your boiling hot pots in after cooking.
Use a mild abrasive cleanser or baking soda and combine with water on the soft side of a sponge. Wipe in a circular motion to remove most stains and scuff marks leftover from pots and pans. Keep applying baking soda and water as needed while softly scrubbing to lift the scuff mark.
