7. Maintenance and Care
Proper care will ensure the longevity and appearance of your Lordear kitchen sink.
- Daily Cleaning: Wipe the sink surface with a soft cloth and mild soap or a non-abrasive cleaner after each use. Rinse thoroughly with water and dry to prevent water spots.
- Avoid Abrasives: Do not use steel wool, abrasive pads, or harsh chemical cleaners (e.g., bleach, ammonia-based products) as they can damage the Nano-PVD finish.
- Prevent Scratches: Use the included bottom rinse grids to protect the sink base from scratches caused by pots and pans.
- Drainage: The sloped basin bottom and X-shaped drainage grooves are designed for efficient water runoff. Ensure the drain assembly is kept clear of debris to maintain optimal drainage.
- Accessory Care: Clean the cutting board, colander, and roll-up rack regularly. The wooden cutting board should be hand-washed and air-dried.
