General sink care
Keep the sink dry. Regularly rinse and towel dry your sink with a soft, dry
cloth when not in use to keep it dry. This will prevent surface deposits and water
spots caused by lime in the water.
Use non-abrasive cleansers. BLANCOCLEAN is a combined cleaner and polish
and will help maintain the original lustre of the sink, however there are other
non-abrasive liquid cream cleaners that can be used. Do not use strong abrasive
cleansers or cleansers that contain chlorine (usually sodium hypochlorite) or hydrochloric
acid, steel wool or metal scrub pads - these will scratch and dull the surface of
Rinse away cleansers after use and wipe the sink dry again to prevent water
spots from forming.
Do not pour paint into your sink. The chemicals in acrylic paint will react
with Silgranit sinks if allowed to sit over 24 hours and will produce permanent
marks. For latex-based paints, try removing any residue immediately using a paint
remover manufactured by the same brand. Consult the paint remover recommendations
before using on any sink.
Use vinegar and water in a mild solution to remove any mineral deposits that
may have built up.
Follow the grain of the steel if using a stainless steel polish. When using
a stainless steel polish, ensure that you read directions carefully. You should
use a damp cloth and follow the grain of the steel when polishing. Rinse with water
and buff with a soft, static-proof cloth for best results. For extra care, test
on a small area first.
Do not drop sharp objects into your sink and do not use your sink surface
as a cutting board as this may scratch or damage the sink. Materials that are harder
than stainless steel can scratch, including stone, diamond, glass, ceramic or abrasives.
Use a sink bottom grid to protect your sink. BLANCO custom-sized stainless
steel grids are available that fit inside the bottom of the sink bowls and protect
the sink from scratches that could be caused by sharp utensils or other kitchen
Rust spots and stains can be removed with metal cleaners such as Flitz®.
Stainless steel does not rust, however rust stains may occur as a result of other
materials coming in contact with the sink allowing iron particles to bond to the
sink surface. Iron particles introduced by metal cookware, steel wool pads, etc.
that react with water can deposit rust spots.
Do not use rubber-coated mats as discoloration of the sink may occur after
prolonged use. Similarly, any wet sponges or cleaning materials left on the sink
for long periods could stain the sink surface.

Use liquid cleaners and rinse well after use, for daily care. Remember also
to use sparingly. A BLANCOCLEAN product is available that is specially formulated

Avoid highly abrasive cleansers. However, a bleach-water solution (50/50)
can be used on Silgranit. For stubborn food stains, pour the bleach solution onto
a cloth and cover the stain. Allow the bleach to sit for at least 1/2 hour and then
clean with a dish detergent and rinse off with water.
Keep extremely hot pots away from the sink. BLANCO SILGRANIT® sinks will
withstand temperatures of up to 280°C. However, modern pots can reach higher
temperatures. Therefore, contact with extremely hot pots should be kept to a minimum.
