1)Regular Cleaning: After each use, wash the stainless steel cooker with warm, soapy water and a soft cloth or sponge. Avoid using abrasive scrubbers or harsh cleaners that can scratch or dull the surface. For tough stains, you can use a mild non-abrasive cleaner specifically designed for stainless steel. 2)To prevent water spots or mineral buildup, dry the cooker thoroughly with a soft towel after cleaning. This helps maintain its shiny appearance and prevents corrosion. 3)Overheating can cause discoloration on stainless steel. Avoid leaving the cooker on high heat for extended periods, and always monitor the cooking process. 4)Use Low to Medium Heat: To preserve the integrity of the stainless steel, avoid using extremely high heat settings for extended periods. Stainless steel can discolor or warp under high heat.
