How to Clean a BLANCO SILGRANIT Sink and White Film

Step-by-step instructions

Step 1: Confirm the surface and clear the work area

Check the sink specification or purchase record for SILGRANIT. Remove dishes, food scraps, loose accessories and a removable grid so the bowl is accessible. Do not loosen plumbing or an installed drain merely to clean the visible basin. Look at the sink when it is dry and note where the film appears; marks around standing-water areas may need a different approach from grease on a sidewall. Keep any product intended for this composite away from adjacent materials unless their care instructions also allow it.

Step 2: Start with daily soil removal

BLANCO's daily cleaning method uses dish soap on a damp soft sponge, followed by rinsing and drying. Work gently over the bowl and rim, lifting food residue instead of scouring it into the surface. A sink that handles cookware is not itself a pan: metal scrapers and aggressive pads are unnecessary for this routine. Pay attention to the area under a grid's feet, where food and soap may collect out of sight. Rinse the sponge as it picks up debris.

Step 3: Judge white film after the surface dries

Rinse the basin completely and wipe it dry with microfiber. Inspect it under the same light as before cleaning. If a chalky haze returns as the water evaporates, consider mineral or soap buildup rather than assuming the composite has faded. BLANCO's SILGRANIT care explanation links many apparent stains to deposits on top of the material. Do not cover the haze with oil as a substitute for removing it. A temporarily darkened wet surface is not proof that the underlying residue is gone.

Step 4: Use the SILGRANIT-specific weekly cleaner

For BLANCO's weekly method, select the Daily+ formulation intended for SILGRANIT, not merely a bottle with the same brand name. Its US instructions describe a 1–2 minute application followed by wiping with a wet cloth or the soft side of a sponge. Follow the bottle for handling and any updated directions. Work in manageable areas so the cleaner is not forgotten beneath an accessory. Use only one cleaning product at a time; do not mix it with bleach, drain cleaner or an improvised stain-removal cocktail.

Step 5: Treat persistent marks according to their cause

If a mark remains, decide whether it is a deposit, a transferred metal streak or actual physical damage. A photograph taken after rinsing and drying helps BLANCO identify the problem. Its international care guidance also discusses suitable acid-based cleaners for mineral deposits, but that does not authorize any concentrated descaler at any strength. Use a product and exposure specifically approved for SILGRANIT. For an unidentified mark, ask for material-specific guidance rather than cycling through solvents, oven cleaner and abrasive powders until something changes.

Step 6: Rinse fixtures and dry all contact areas

Flush away cleaner from the bowl, rim and accessible drain edge. Clean the faucet, strainer and accessories according to their own finish or component instructions; a chrome fixture or coated grid need not share the basin's chemical tolerance. Wipe the sink dry, then check underneath removable items before returning them. This step matters because residue trapped under a foot or mat can recreate a visible patch. If a cleaner has splashed onto another surface, remove it promptly in the way that surface's manufacturer recommends.

Step 7: Maintain the sink without chasing a showroom finish

Rinse away food and wipe the bowl dry as a regular habit, especially where hard water leaves deposits. BLANCO recommends daily cleaning and a deeper weekly routine, but adjust attention to actual use and buildup. Do not confuse stain resistance with a promise that the sink never needs cleaning. Inspect any chip, crack or persistent rough area before continuing aggressive treatment; those are not normal surface deposits. The goal is a clean, residue-free working sink, not repeated chemical treatment solely to make a wet color last.
