12 Questions from the Community

  • I have purchased the Blanco 440179 in Cafe Brown. What products are recommended for cleaning the sink and to help retain the color?

    A. Per Blanco's website: GENERAL CARE & CLEANING: Daily cleaning may be done with any non-abrasive cleaner (i.e. BLANCOCLEAN Composite Sink Cleaner). After every use, rinse and wipe the sink dry with a clean, soft cloth to eliminate any water spots or soap film build-ups. REMOVING STAINS AND MINOR SCUFF MARKS: Normal Stains ~ For stains, please use BLANCOCLEAN, along with a soft scouring pad. 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. Finally, clean with BLANCOCLEAN to put a protective coating back on the sink's surface. LUSTER: BLANCOCLEAN can be used to help bring back the luster. Follow the directions on the bottle. MISCELLANEOUS: To remove Calcium Deposits (a white ring around the bottom of your sink): use LIME AWAY To remove Adhesive Labels: use Acetone (nail polish remover) Note: Always test non-Blanco branded stain remover in a small, non-visible location WHAT NOT TO USE: 1) Do not use any abrasive cleaning agents or scrub pads, such as Steel Wool 2) Straight bleach 3) Commercial alkalis, such as ammonia and/or caustic solutions 4) Drain blocking chemicals that involve filling the sink with water Note: Always test non-Blanco branded stain remover in a small, non-visible location
