General Care and 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.


BLANCOCLEAN can be used to help bring back the luster. Follow the directions on the bottle.


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

Good luck.
