Blitz All Metal Shine Polish cleans and restores the original brilliance to brass, copper, chrome and stainless steel. This product contains no alcohol, no ammonia, no acids, no V.O.C. and no abrasives. CRITICAL: If an item is used for cooking, it is essential you insist that the cookware be washed thoroughly for sanitary reasons. Water marks might need several treatments to remove. Stainless steel is an alloy of steel and other metals. It comes in many grades. The usual rule of thumb is if a piece of stainless steel is magnetic it has the possibility of rusting. If it is non-magnetic it tends not to rust. Stainless may have a brushed look or a high mirror finish, and our cloths work well on these items if used properly. A typical application is to clean stainless steel refrigerators, sinks or cookware. It works well on ornaments and other stainless steel, too. What about stainless steel refrigerator doors? These doors are usually made of brushed steel but caution should be used. Aggressive rubbing on refrigerator doors will polish the brushed look and make it look a bit different. In some cases, the stainless steel may not be stainless steel (maybe it is soft steel or aluminium?), therefore the use of the polish will make the metal shine. There are instructions that come with the appliance and should be followed.
