Chemical Rust Removers: Acid-Based: These contain strong acids (like phosphoric or hydrochloric acid) that react with rust to dissolve it. They’re effective but can be harsh and may require safety precautions. Examples: Naval Jelly, Loctite Rust Dissolver. Chelating Agents: These are milder, water-based solutions that bind to rust and remove it without damaging the underlying metal. Examples: Evapo-Rust, WD-40 Specialist Rust Remover Soak. Rust Converters: These convert rust into a stable, paintable surface. They’re useful when complete rust removal isn’t practical. Examples: Corroseal, Rust-Oleum Rust Reformer.
