The RailEasy E0100-K000 Stainless Steel Railing Care Kit includes everything you'll need to keep your stainless railing system clean and protected. The kit includes a passivating fluid spray bottle, a car wash soap bottle, a cup of metal polish, and a microfiber polishing cloth. First, clean the metal with the car wash soap, then use the metal polish to provide a protective layer. If the metal surface scratches, the passivating fluid will neutralize any possible contamination of the stainless surface.
