6. Care and Maintenance

The SILGRANIT material is highly resistant to scratches, stains, and heat, making it easy to maintain. Regular cleaning will keep your sink looking new.

6.1 Daily Cleaning

Wipe down the sink with a soft cloth or sponge and mild dish soap after each use.
Rinse thoroughly with water.
For stubborn residue, a non-abrasive cleaner designed for granite composite sinks can be used.

6.2 Stain Removal

For tough stains, create a paste of baking soda and water, apply to the stain, let sit for a few minutes, then scrub gently and rinse.
Avoid harsh chemicals, abrasive cleaners, steel wool, or scouring pads, as these can damage the surface.

6.3 Heat Resistance

The sink is heat resistant up to 536°F (280°C). While it can withstand high temperatures, it is always recommended to use a trivet or hot pad for extremely hot items to prevent potential thermal shock or discoloration over time.

7. Troubleshooting

Problem	Possible Cause	Solution
Water spots or mineral buildup	Hard water deposits	Wipe dry after each use. Use a 50/50 solution of white vinegar and water to dissolve deposits, then rinse thoroughly.
Dull appearance	Residue buildup or lack of regular cleaning	Clean with a mild abrasive cleaner (e.g., Bar Keepers Friend) or a specialized granite composite sink cleaner. Rinse well.
Scratches	Heavy impact or sharp objects (rare due to material durability)	Minor surface marks can often be buffed out with a non-abrasive pad and cleaner. Deep scratches may require professional attention.
