Cleaning stainless steel with pastes can cause scratches in the stainless steel due to the abrasive methods used to clean the steel. Overtime, this will remove the chromium film on the stainless steel which prevents rust. Chromium improves the corrosion resistance by forming a chromium oxide film, a very thin layer on the steel, so removing this film using pastes decreases the resistance to corrosion and the elements.
Spray and aerosol cleaners are non-scratch meaning they are ideal for cleaning stainless steel surfaces that need to appear polished. Quean Clean Stainless Steel Cleaner & Polish is an aerosol which makes it perfect for any steel surface and also leaves a protective barrier to prevent future damage from stains or scratches.
