Stainless steel can be cleaned using branded stainless steel cleaners available from trade suppliers or groceries. Improper cleaners can cause staining or corrosion. Acid-based products must not be used. When cleaning use nylon or another non-scratching scourer. When the direction of the ‘grain’ is visible, clean in that direction.

If staining or scratching has occurred, or you need to polish your stainless steel, use a proprietary stainless steel cleaner. Some of these cleaners and polishes can help minimize scratching and remove stains. They can also polish stainless steel surfaces. Read the directions on the stainless steel cleaner and test in an inconspicuous spot. Be sure to rinse thoroughly and towel dry. 

Stainless steel can be contaminated by the pick-up of carbon steel ("free iron") and this is likely to lead to rapid localized corrosion. Do not use strong acid solution or abrasive cleaners. Do not use steel wool, steel brushes or other cleaning materials that contain steel as these can cause rust.
