About the Product Our steel rust remover contains sodium gluconate and sodium hydroxide. It can quickly react with rust on the metal surface, effectively removing the rust layer and restoring the metal surface's smoothness. A strong protective film is formed on the metal surface, effectively isolating air and moisture, preventing the metal from rusting again and extending its service life. Its usage is simple: Clean and dry the area to be rusted, spray it directly on the rusted area, and let the spray soak into the rust layer. Wipe the surface clean and repeat the application until all rust is removed. It is also stable and durable, maintaining excellent performance even in harsh environments, and reducing coating peeling or discoloration caused by environmental factors.
