Stainless steel appliances can easily show fingerprints, smudges, and water spots, so it's important to keep them clean and shiny. Use a soft cloth or microfiber towel with a mild stainless steel cleaner to wipe away any marks or stains. Avoid using abrasive cleaners or scrub brushes that can scratch the surface. Regular cleaning will help maintain the beauty and shine of your stainless steel appliances.
