Stainless-steel cutlery is relatively stainproof, but occasionally a cleaning solution or hard water can leave stains or marks. Common causes of stains on stainless steel include hot grease, strong detergent and condiment vinegar. Steel-wool fragments can cause stainless-steel cutlery to develop a rust-coloured stain. Silver cleaner contains acid that etches the steel to a dull grey. Careful cleaning and care of your stainless-steel cutlery can help prevent and treat stains.
