Use warm water and a soft cloth or non-abrasive sponge to clean normal spills and small stains. Where necessary, use a mild soap or detergent to clean stainless steel surfaces. Use recommended solvents such as non-sterile or sterile 70% isopropyl alcohol to clean more stubborn messes such as grease, oil, stains, and fingerprints. Use a clean cloth over all surfaces to prevent water spots.
