Cleaning and Maintenance
Silgranit sinks are extremely easy to clean, making them a great choice for busy households. A sponge and a little washing-up liquid are enough for daily cleaning.
For limescale buildup, use a professional descaling agent like CLR or vinegar with hot water. Apply the descaling agent to the areas with limescale buildup and let it soak for at least 2 hours.
Daily cleaning and care could hardly be faster with Silgranit. In about the time it takes to brush your teeth, you can rinse off large dishes and wipe down your sink. Drops of sauce run off into the bowl practically by themselves.
Regular rinsing and wiping down with mild dish soap and warm water will help maintain your light-colored sink. You can also use baking soda on a damp cloth to remove marks.
For deeper cleaning, you can use dishwasher tablets. Fill your sink with 1–3 cm of HOT water, dissolve a tablet in the water and let it sit overnight. In the morning, scrub it down with a scotch-brite nylon pad and then thoroughly rinse with dish soap and water.
Silgranit's non-porous surface repels liquids, making it resistant to stains from coffee, wine, and other common kitchen spills. Cleaning is simple—just a quick wipe with soap and water is enough to keep it looking fresh.
