Ideal Home notes that stainless-steel appliances may have a protective coating that can be damaged by scratching. Its experts recommend regular cleaning with a damp microfiber cloth and mild washing-up liquid where permitted. Work in the grain's direction rather than repeatedly rubbing across the visible brushed pattern.

Protect Appliance Coatings While Removing Steel Fingerprints

Remove residue with clean water and dry with a soft cloth to limit watermarks. Check the appliance manual before substituting vinegar, polish or abrasive powder, since the coating may set stricter limits than bare stainless steel. Keeping up with light marks reduces the temptation to use force when grease and fingerprints have accumulated across a larger area.

Regular mild cleaning and wiping with the grain help preserve the original finish.
