Nox-Rust Premium Rust Removing Gel is a fast-acting, water-based, brush-on rust remover. Safe and effective, the gel can remove surface rust from large, hard-to-move vertical metal structures and equipment without the need for sanding or scrubbing. Thick and acid-free, the gel is applicable on iron, steel and most metal surfaces while ensuring that paint or rubber are damage free.
To apply, brush the gel over the rusted metal surface. Light rust will begin to break within 15-20 minutes. When the rust is loose, wipe away using a soft cloth or rinse with water.
