Castrol Rust Remover is used to loosen and remove rust from ferrous metal parts, chassis sections, and tools affected by corrosion. Its chemical formulation also provides lubricating and anti-corrosive properties, helping you free up seized components while reducing the likelihood of future rust build-up.Explore the key features that support rust removal and long-term protection:Penetrating Lubricant Formula: Developed to penetrate deeply into rusted threads and joints, this formula loosens seized parts with minimal effort and restores basic mechanical movement in corroded assemblies.Anti-Corrosion Additives: Contains dedicated anti-corrosion agents that leave a protective film on treated surfaces, helping to inhibit further rust formation and extend part lifespan after treatment.Resin-Free Composition: Made without resin, which prevents sticky residue after application, making clean-up quicker and leaving the surface ready for immediate use or further treatment.Silicone-Free Chemistry
