Stainless Steel Care Tips

• Clean daily with mild soap or non-chloride detergent; rinse & wipe dry.
• Avoid abrasive pads, wire brushes, or cleaners containing chlorine bleach.
• For stubborn residue, use Bar Keepers Friend® applied with a wet plastic scouring pad, following the grain.
• Finish with John Boos Stainless Steel Cleaner to restore the protective sheen.

Proper maintenance preserves the passive film that makes stainless steel rust-resistant and keeps your sink looking new.
