Care and Maintenance
To ensure the longevity and appearance of your BLANCO ANDANO 500-U stainless steel sink, follow these care instructions:
- Daily Cleaning: After each use, rinse the sink thoroughly with clean water to remove food particles and soap residue. Wipe dry with a soft cloth to prevent water spots and mineral buildup.
- Regular Cleaning: For more thorough cleaning, use a mild dish soap or a specialized stainless steel cleaner with a soft sponge or cloth. Always rub in the direction of the grain of the stainless steel.
- Avoid Abrasives: Do not use abrasive cleaners, steel wool, or scouring pads, as these can scratch the satin finish of the stainless steel.
- Prevent Stains: Avoid leaving acidic foods (e.g., citrus, tomatoes) or harsh chemicals in contact with the sink surface for extended periods, as they can cause discoloration or damage.
- InFino Drain Cleaning: The InFino basket valve is easily removable for cleaning. Periodically remove and clean it to prevent blockages and maintain hygiene.
Troubleshooting
This section addresses common issues you might encounter with your BLANCO ANDANO 500-U sink.
Slow Drainage
If you experience slow drainage, check the InFino basket valve for food debris or blockages. Remove the basket and clean it thoroughly. Ensure the drain pipe connections are clear and free from obstructions.
Water Spots or Stains
Water spots are common with stainless steel, especially in hard water areas. To prevent them, wipe the sink dry after each use. For existing spots, use a stainless steel cleaner or a solution of vinegar and water, then rinse and dry.
Scratches
Stainless steel can scratch. Minor scratches often blend into the satin finish over time. Avoid abrasive materials during cleaning to minimize new scratches. For deeper scratches, consult a professional or BLANCO customer support.
Leakage
If you detect any leaks, immediately check all plumbing connections under the sink. Ensure all nuts are tightened and that the sealant around the sink rim is intact. If the issue persists, contact a qualified plumber.
