Laminate countertops are generally not recommended for undermount installations.

Care & Maintenance Guide
1. The Beauty of Natural Copper
Copper is a living material.
Over time, your sink will naturally develop a rich patina that enhances its character and uniqueness.
This natural aging process is expected and considered one of copper's most desirable qualities.
Each sink will age differently based on usage, water conditions, and environment.
2. Daily Cleaning
For everyday maintenance:
- Rinse the sink with warm water.
- Use a soft cloth or sponge.
- Clean with mild dish soap.
- Dry with a soft towel if desired.
Regular cleaning helps maintain the sink's appearance and performance.
3. What to Avoid
Do not use:
- Steel wool
- Abrasive scrub pads
- Harsh chemical cleaners
- Bleach
- Ammonia-based products
- Acidic drain cleaners
These products may damage the finish or accelerate uneven patina development.
4. Water Spots & Mineral Deposits
In hard-water areas, mineral deposits may occasionally appear.
To remove them:
- Use mild soap and warm water.
- Wipe gently with a soft cloth.
- Dry thoroughly after cleaning.
Avoid aggressive scrubbing.
5. Scratch Resistance
Minor scratches are normal and become less noticeable as the sink develops its natural patina.
Unlike stainless steel, copper naturally blends small marks into its evolving finish over time.
6. Will My Copper Sink Turn Green?
Under normal indoor residential use, your NAUXUS copper sink should not develop excessive green oxidation.
Proper cleaning and routine use help maintain a beautiful, rich copper appearance.
In rare cases, exposure to standing water, harsh chemicals, or outdoor environments may accelerate patina changes.
7. Food Safety
Copper naturally possesses antimicrobial properties that help reduce the presence of certain bacteria on the sink surface.
For best hygiene practices:
- Clean regularly
- Rinse after food preparation
- Avoid prolonged contact with acidic foods
8. Warranty Information
