Note from DirectSinks about the KWT311-15-316 - This small Prep Station Bar sink is made of 16 Gauge Marine Grade Stainless Steel.

This is an excellent choice for a Fishing Boat, RV, Marina and also an Ocean -Front outdoor residential Kitchen.  

  The key difference to a Marine Grade 316 Stainless Steel compared to a Stainless Steel of a 304 grade is the corrosion resistance against chlorides and acids. This is achieved by adding  2-3% molybdenum to the content of the alloy. 

Sodium chloride (NaCl), is what is known as commonly known as salt.  The salt in the ocean is also Sodium Chloride and often carries various trace minerals.

Maintenance Tips

• Rinse & Dry After Use: Always rinse and wipe dry to prevent water spots and salt/mineral buildup—especially important for outdoor exposure.
• Use Mild Cleaners Only: Clean with dish soap or stainless steel cleaner; avoid bleach, acids, and harsh chemicals.
• Protect Marine-Grade Steel: Even T-316 stainless resists corrosion, but regular cleaning helps maintain maximum rust resistance in outdoor environments.
• Avoid Abrasive Pads: No steel wool or rough scrubbers—use soft sponges to preserve the brushed finish.
• Remove Debris Quickly: Clear food, leaves, or outdoor residue to prevent staining and clogging.
• Descale Periodically: Use diluted vinegar for hard water spots, then rinse thoroughly.
• Maintain Accessories: Clean cutting board and sink cover after each use and store dry.
• Check Drain Regularly: Keep drain strainer clear for smooth water flow in outdoor use conditions.
• Seasonal Care (Outdoor Tip): In coastal or humid areas, wipe down more frequently to maintain long-term corrosion resistance.
