This multipurpose, biodegradable cleaner easily restores your NanoBond cookware to its original brilliance by removing temporary bluing/discoloration that can result from a combination of high heat, trace minerals and oil residue. Note: Not for use with other Hestan stainless steel cookware (including ProBond®, Thomas Keller Commercial Clad™, or Provisions™ OvenBond and Accessories). Abrasion may occur.
