Care & Maintenance Tips

• Clean daily with mild soap, warm water, and a soft cloth; always wipe in the direction of the grain.
• Avoid chlorine bleach or harsh, chloride-based cleaners—these can damage the protective finish.
• For tough stains, use Bar Keepers Friend® with a non-metallic pad, rinse, and polish with John Boos Stainless Steel Cleaner.

Following these guidelines preserves the passive film on Type 300 stainless steel, preventing corrosion and keeping your sink looking new.
