How To Restore a Silgranit Style Sink

● Stubborn Stains – Light colored Silgranit sinks are more prone to damage and in the event that it gets stained, you can restore it using a mixture of equal parts chlorine bleach and water.

Simply wipe down your sink with the mixture using a soft dishcloth or a sponge. Do not use bleach directly on the surface as this will damage its protective coating.

You can also use Blancoclean Composite Cleanser to eliminate any stubborn stains.

● Limescale and Calcium Deposits – Although Silrganit sinks can repel surface stains, hard water can leave behind a white residue on the surfaces. These limescale deposits can absorb liquids and can reduce the luster and appeal of your sink in the long run, so make sure to address them early.

To remove limescale build up, you’ll need a commercial descaling agent like CLR (Calcium Lime Rust) or Lime Away. These products are used to dissolve stains like lime, calcium and iron oxide.

Apply the descaling agent to the areas with limescale then let it soak for at least 2 hours. Rinse with hot water, wipe using a damp sponge and make sure to dry it thoroughly with a soft cloth. Be sure to follow the instructions when using these cleaning agents to avoid any damage.

Alternatively, you can also use an even mixture of white vinegar and warm water. Apply the mixture to the limescale build-up and rinse the sink thoroughly with some water. Wipe dry with a soft, clean cloth.

● Restoring the Luster of your Silgranit sink – If your finish isn’t looking as shiny as it did, apply some mineral oil on it using a soft, clean cloth. Wipe it down gently until it looks lustrous again.

● Soap Scum – Some cream cleaners can leave a white film on a dark-colored Silgranit sink. If you also do not rinse your surfaces thoroughly, soap scum can built up, but this can easily be removed using Mr. Clean Magic Eraser.

Apply this to your sink and then rinse it thoroughly with some mild dish detergent and water. Make sure to dry it with a soft, clean cloth. If you want to bring back its dark sheen, you can also apply some mineral oil after it dries.

Sink Scratches

Silgranit sinks are extremely durable and resistant to scratches. Sometimes, metal utensils or pots can leave a temporary mark on the sink’s surface, and this can be scrubbed off easily.

Use a rough sponge for scuff marks, and sprinkle some baking soda and warm water in your sink. Scrub off the marks gently with the rough sponge and these will be instantly removed.

  1. I had a Blanco Silgranit metallic gray since for 3 years and loved it. Never had one problem with stains or limescale even with hard water. I was meticulous about cleaning it every single day and always used a microfiber cloth on it after the last use of the day. Fast forward to one year ago, built our new house and I, of course, purchased my second metallic gray Silgranit huge single bowl sink. We even installed a whole house water softener this time around. I have had the worst time with this new sink!! I’ve never been one for filling a sink up full of soapy water and doing dishes that way. I just wash what I need to one at a time under running water with liquid dish soap. Occasionally, I will fill a pot that needs cleaning and wash my other dishes out of that one. I only pour liquids directly down the drain and NEVER set dirty dishes in the sink. This new sink even detects one speck of oil and it turns into a dark spot for days. When I wash a skillet in the sink under running water, I immediately have to smear dish soap over the sink’s wet surface and rinse any oily residue away or it will leave marks. The limescale is what I’m fighting on an every day basis. I thought the water softener would eliminate the mineral buildup but it just settles in the drain grooves and creates rings around the compactor drain. The sink was installed correctly with the correct slope.  Water doesn’t seem to pool in spots but if I don’t wipe it dry every single time, lime deposits will eventually be created.  I’m a bit obsessive on how to use the sink (its a sink!!!) because I know what high maintenance it takes to keep it from becoming a disaster. Would love to know if I could somehow seal it because it seems so porous or how to combat the white limescale/mineral deposits. Even when I’m constantly wiping it dry…maddening and I’d rip it out in a heartbeat if it weren’t for the super odd shaped hole it would leave cut out of the granite. ….sigh……

    1. Hi Tracy, thank you for sharing your experiences and your Silgranit sink review.

      The manufacturers at Blanco recommend using warm vinegar or a vinegar based cleanser to clean stubborn stains on this type of sink. Then letting the cleanser sit for a few minutes before washing it down with water and letting dry. If that doesn’t work a bleach water solution can be used on the stain and left on for 30 minutes before washing down.

  2. Hi Tracy, I purchased a Blanco Silgranit Concrete Gray sink less than a year ago and I too have a problem with persistent stains left by any dish, cup, glass etc. left in the sink over night. A noticeable ‘ring’ where the dish or cup sat in the sink is quite obvious the next morning. Even if said dish only has water sitting in it to soak for several hours over night, it leaves a ring underneath where it sat. I am able to remove the stain by leaving a vinegar soaked cloth on the stain for several hours. That’s good that it does clean up BUT, WHAT A NUISANCE. It’s a sink for crying out load. One would think a kitchen sink would tolerate a few dishes sitting in it without having to go through so much trouble to maintain it. If I had any idea of this issue I never would have purchased this sink. I contacted Blanco describing the problem and asked if I could SEAL the sink with a granite sealer or something to help prevent the staining.They did NOT answer my question. Their only response was how to clean the sink which I already knew.

    I must say that I love the sink in every other way especially how it looks but I am very unhappy with the staining. Generally I am pretty meticulous about cleaning dishes without letting them sit too long in the sink but once in a while it is nice to know you can without worrying about staining. Anyway, I said my piece. Just wanted you to know that you are not the only one with this problem.

    1. Hi Brian, thank you for sharing your experiences with your Blanco Silgranit concrete sink. This is very useful information to consider when making a purchase of this product.

  3. I bought this sink 10 years ago and now hate it. There is no finish left on it, stains so easily and grows mold and mildew every few days. Unfortunately it’s mounted under a granite countertop and the experts say the granite may break if I try to replace the sink. I would never recommend this sink and dream about a stainless steel sink.

  4. Oh dear. I just bought one of these sinks! I loved the look of them. There was convincing manufacturers’ information regarding durability, stain/scratch resistance etc. I wish I’d read these comments beforehand. Also I’ve since read their customer service is poor.
