3 1 vihaanpipes.com CARE OF STAINLESS STEEL Specification Testing The cleaner stainless steel can be kept while in storage, being processed or during use, the greater the assurance of optimum corrosion resistance. Some tips on the care of stainless steel are listed for your reference. 1. Use paper or other protective wrapping on the surface of stainless steel until processing is complete.. Handle stainless steel with clean gloves or cloth to guard against stains or finger marks. 3. Avoid the use of oily rags or greasy cloths when wiping the surface. 4. Do routine cleaning of exposed surfaces. Buildings with window washing systems can utilise this method to clean exterior panels. 5. Where possible, after cleaning, rinse thoroughly with water. 6. Cleaning with chloridecontaining detergents must be avoided. 7. Even the finest cleaning powders can scratch or burnish a millrolled finish. On polished finishes, rubbing or wiping should be done in the direction of the polish lines, NOT across them. 8. DO NOT USE SOLVENTS in closed spaces or while smoking.
