Care and Maintenance
Proper care will preserve the beauty and longevity of your BLANCO stainless steel sink. Stainless steel is durable but requires regular cleaning to maintain its finish and prevent water spots or corrosion.
Daily Cleaning:
- After each use, rinse the sink thoroughly with clean water to remove any food particles or residue.
- Wipe the sink dry with a soft cloth to prevent water spots, especially in hard water areas.
Weekly 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 to avoid scratching.
- Rinse thoroughly and dry completely.
Avoid:
- Abrasive cleaners, steel wool, or scouring pads, as these can scratch the surface.
- Bleach or cleaners containing chlorine, as they can cause pitting and corrosion.
- Leaving acidic foods (e.g., citrus juices, tomato products) or harsh chemicals on the surface for extended periods.
Troubleshooting
This section addresses common issues you might encounter with your BLANCO CRONOS XL 8-IF sink.
| Problem | Possible Cause | Solution |
|---|---|---|
| Slow Drainage | Clogged basket valve or drain pipe. | Remove the InFino basket valve and clean out any debris. If the issue persists, check the P-trap for blockages. |
| Water Spots/Stains | Hard water deposits; not drying the sink after use. | 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 on Surface | Use of abrasive materials or sharp objects. | Minor scratches are normal with stainless steel over time. For deeper scratches, consult a professional or use a specialized stainless steel scratch removal kit (use with caution and follow product instructions). Prevent by avoiding abrasive cleaners and sharp objects. |
| Sink Leaks | Loose plumbing connections or improper sealant application. | Check all plumbing connections under the sink for tightness. Reapply sealant around the sink rim if necessary. If leaks persist, contact a qualified plumber. |
