I have a Blanco Anthracite-colored Silgranit sink. This cleaning product is great! I can once again see the "glittery" type sheen that I loved when I first got the sink. Use 1 to 2 times a week for best results depending on how much you use your sink. IF you READ the instructions and APPLY it correctly, it does wonders. (Note: The last video I saw on its use showed the user just randomly squeezing some on in a puddle and letting it set without spreading it out to cover the entire surface of the sink. You have to get the product on all surfaces for it to work. Squeeze some on a sponge and spread on a coating on all surfaces and you'll get great results - plus, you won't use it all up so quickly by spreading on a coating verses if you just squeeze it on in puddles!)

Delayed getting this Sink Cleaner for my Blanco Sink... should have bought it sooner - works well and keeps the black color more even. Happy with it. Note that the product is clear and comes out of the container fast, so go easy or you will use or waste more than you need! Read more

It’s an ok product, but its biggest claim to fame may be that it’s a “Blanco” (And I do love my new Blanco Silgranit kitchen sink in gray)! Read more

I'm giving this 5 stars because it does work great for cleaning a Blanco Silgranit Sink. However, honestly it isn't any different that using regular dishwashing soap. My go to for cleaning our sink is a scrubby sponge with regular dish soap. For a stubborn mark from a pan, I use a bit of Barkeeper's Friend. Works awesome. So, while this cleaner works great - it isn't special or unique from regular soap. Read more

I had high hopes that this was going to help eliminate the soap and water stains on my brown composite sink. I even let it sit a couple of hours, did not see any change. May work if you start out using it right away. My sink is two years old and I was only using bars keeper for cleaning it before this purchase. Will keep looking for a product to clean it. Read more

I am so disappointed with this product. It does not clean my new sink very well at all and is much too expensive for regular use. There are many stains that remain after cleansing with this product. I am going to try other products in the future. Read more

This is the second time I bought this sink cleaner. It works well for my black Blanco sink. A little bit of cleaner goes a long way and I know it won’t scratch it or fade the dark color. I highly recommend using it on Blanco sinks instead of the typical household cleaners. Read more
