Contaminants on stainless steel gates and turnstiles, such as:

  • Cement and mortar – clean with a solution containing a small amount of phosphoric acid, followed by water (preferably demineralized).
  • Iron particles from tools – clean mechanically at an early stage; if deposits appear, use pickling and passivation pastes.
  • Paints – clean with paint removers based on alkaline compounds or solvents.
  • Limescale deposits – clean with alcohol-based agents (including methylated spirits and isopropyl alcohol), solvents (e.g., acetone), or chrome cleaning products.
  • Fingerprints – clean with soap and water or detergent, or chloride-free glass cleaners.
  • Others – can be cleaned with stainless steel cleaning products from manufacturers such as BERNER, WURTH, or 3M.
