All exposed stainless steel surfaces should be cleaned by wiping with a clean cloth, dampened with a mild detergent in warm water on a monthly basis.
Heavily used areas may need more frequent cleaning. Stainless steel can be brightened by polishing with a cloth dipped in vinegar or ammonia. Polish dry with paper towel.
Stubborn dirt or stains can be removed with mild, non-scratching abrasive powders (typical household cleaners). These can be used with warm water, bristle brushes or clean cloths. Vinegar can be added to the powder for a more aggressive clean. Always rinse the area with clean hot water and wipe completely dry. Polish with a soft cloth or paper towel to prevent water spotting.
To remove mineral deposits use a weak solution of vinegar and water. Heat marks can be removed by moistening a soft cloth with undiluted vinegar and wiping over the area. Do not leave the vinegar in contact with the surface - wipe off immediately.
To remove fingerprints or smears use a commercial stainless steel cleaner or olive oil. Note that olive oil is suitable only for matt finish stainless steel, not mirror finish.
White stains on stainless steel can be removed by rubbing them with a Scotchbrite® pad and water. Rub with the grain of the steel, not across it. Never use steel wool or abrasive pads that contain soap as this will induce rust.
Carbon steel brushes and steel wool should not be used as they may leave particles embedded in the surface of the stainless steel, which can lead to rusting.
Chlorine bleach should not be used to clean stainless steel as it will attack the protective layer on the stainless steel.
