How to Clean Blanco Sinks

Blanco is a manufacturer of kitchen and bar sinks. It has been in business since 1925, when Heinrich Blanc's small company began to make copper parts for hot water bottles and stoves. Blanco sinks are made of two materials--stainless steel and a granite and resin composite material called Silgranit. Both types of Blanco sinks are easy to clean without a lot of effort.

Things You'll Need

  • Soft dishcloth

  • Towel

  • Lime removing agent

  • Sponge

  • Non-abrasive cleanser

  • Bleach

  • Measuring cup

Clean Blanco Stainless Steel Sinks

Step 1

Rinse a Blanco stainless steel sink with plain water after washing dishes or discarding food.

Step 2

Dry the sink with a soft dish cloth to prevent lime deposits and other hard water stains from remaining on the stainless steel finish.

Step 3

Clean away mineral deposits with a lime remover cleansing agent and a soft cloth or sponge. Avoid using abrasive cleanser that can scratch the stainless steel surface.

Clean Blanco Silgranit Sinks

Step 1

Wipe down a Blanco Silgranit sink with a soft sponge or cloth after using. Dry with a towel.

Step 2

Clean small stains that mark the finish of a Blanco Silgranit sink with a non-abrasive kitchen cleanser and a clean sponge.

Step 3

Disinfect a Blanco Silgranit sink with a solution of equal parts bleach and water. Sponge the solution around the inside of the basin without letting the bleach pool in the sink for too long. Prolonged exposure to bleach can ruin the finish of Silgranit.


Although an abrasive cleaner should not be used on a Blanco stainless steel sink as part of a normal cleaning routine, it can be used carefully to buff out scratches. Apply a small amount of such a cleanser on a plastic scrubber sponge. Gently rub it into the scratch to even it out.
