How To Clean A Blanco Silgranit Sink

Blanco’s Silgranit sinks are a staple in many kitchens throughout the country. The kitchen sinks consist of a composite material made with up to 80 percent natural granite and acrylic resin. The combination of the two creates a robust and non-porous sink resistant to heat, scratches, and chips. 

Silgranit sinks require basic care and maintenance, but there are a few things you should know. If you have a Silgranit sink (or you’re considering one), continue reading to learn how to clean these beauties. 

What Not To Use on Silgranit Sinks

Like most granite composite sinks, there are a few cleaners, products, and techniques to avoid using while cleaning a Blanco Silgranit sink. Although many of us automatically reach for our favorite cleaner that is chock full of chemicals, try to resist the urge to use those on your sink. 

Abrasive cleaners can damage the sink’s surface, leaving it dull and susceptible to additional damage. In addition, avoid using harsh scrubbers, like metal scrub pads or steel wool, to clean the sink. These can scratch and dull the surface. In addition, they may leave corroded, rusty patches on the sink’s surface if left on the sink when they’re wet.

One of the strangely specific major no-nos when it comes to Silgranit sinks is acrylic paint. Do not pour acrylic paint into your sink. The chemicals in the mixture will react with the sink if it sits for too long. It’ll leave permanent marks on your beautiful sink, so avoid pouring any type of paint down the drain. 

What Kind Of Daily Care Do Silgranit Sinks Require?

Silgranit sinks are pretty easy to maintain. They’re non-porous, meaning they don’t absorb liquids, making them stain-resistant and straightforward to clean. In addition, they come with a unique surface protection formula, called Hygienic+Plus, which reduces bacteria growth by about 98%. 

If you stay on top of care, your sink will last for many years to come. Daily maintenance consists of a basic routine that shouldn’t take longer than a few minutes. This helps clean everyday grime, preventing stains from taking hold. 

Here’s what you’ll need:

  • Mild dish soap
  • Soft sponge
  • Microfiber cloth
  • Clean water

Start by saturating a soft sponge with warm to hot water. Apply a small amount of dish soap to the sponge, then wipe the surface of the sink in small, circular motions. Once you clean the entire surface of the sink, rinse the suds away with clean, warm water. Dry the sink completely with a soft, microfiber cloth. 

How Do You Deep Clean A Silgranit Sink?

Deep cleaning a Silgranit sink is surprisingly easy, so there’s no need to pull out the elbow-high rubber cleaning gloves for cleaning. Blanco recommends deep cleaning Silgranit sinks at least once or twice per year. 

Here’s what you’ll need to get the job done:

  • Mild liquid/gel laundry detergent
  • Microfiber cloth
  • Sink drain plug

This process takes at least a few hours, but preferably overnight, so it’s a good thing to do before bed. Close the sink drain with the plug and apply a thin layer of laundry detergent to the sink surface, spreading it evenly. 

Fill the sink with hot water, heated to 140 degrees Fahrenheit or 60 degrees Celcius. Let it sit and do its job for at least two hours, preferably overnight. 

Drain the sink once the solution has sat for at least a few hours. Rinse the leftover suds away with clean water, then dry the sink with a microfiber cloth. 

How Do You Get Stains Out Of A Blanco Granite Sink?

In some cases, stubborn stains take root despite your best efforts. Lighter-colored Silgranit sinks are more prone to stains. If the stains require more effort than a quick wipe, use equal water and bleach mixed together. 

Use a soft towel or sponge to remove the stains. Don’t use undiluted bleach, as it’ll damage the protective coating on the sink. 

If you’d prefer not to use bleach, use vinegar. Warm up a small amount of warm vinegar, then apply it to the stain. Allow it to sit for a few minutes, then rinse the area with clean water. Dry the sink with a microfiber cloth. 

Baking soda is another handy tool for tackling tough stains. Apply a generous coating of baking soda to the stained areas. Use vinegar in tandem with the baking soda. This produces a reaction that helps pull out any residual marks and stains. 

Give it a few minutes to work, then gently scrub away the stains with a soft sponge. Rinse the area completely clean with warm water. Use a microfiber cloth to dry the sink. 

How To Remove Limescale Or Calcium Deposits

Limescale is a common issue that leaves discoloration and deposits in your sink. Blanco offers a cleaner, called BLANCOCLEAN Daily+ Cleaner, that can tackle these deposits.

  • SPECIALTY CLEANER: Specially formulated for cleaning BLANCO SILGRANIT sinks
  • GENTLE FORMULA: Use once or twice a week to safely maintain the sink’s surface
  • REDUCES LIMESCALE: Keeps hard water deposits and limescale under control
  • REMOVES SOAP SCUM: Reduce residues and white film caused from dish soap and other cleaners

Calcium deposits are another issue you may contend with. If you have hard water in your home, you may end up with white residue in your sink, making it appear dirty. Removing calcium deposits is typically relatively easy, and you have a few options to choose from. 

If you prefer to avoid chemicals, use an equal-part mixture of white vinegar and water to remove the stains. Allow the mixture to sit on the offending deposits, then rinse the sink thoroughly to remove residue. 

Commercial cleaners, including CLR and Lime Away, are safe to use on Silgranit sinks. Simply follow the manufacturer’s instructions.
