[Efficient Stain Removal and Anti-Oxidation] Uses a neutral, environmentally friendly solvent to quickly dissolve oil stains, fingerprints, and stubborn dirt, preventing strong acids and alkalis from corroding the plating. After cleaning, it leaves no water marks on the while forming a transparent protective film that blocks air and slows down oxidation and yellowing. [Coating Repair and Polishing 2-in-1] Contains nano-sized polishing particles to gently fill fine scratches and restore a mirror-like gloss. Special care ingredients repair matte caused by sun exposure and aging, restoring parts to their factory-quality luster. [Long-Lasting Rust Protection] Added with a polymer corrosion inhibitor, it forms a dense, hydrophobic layer on the metal, effectively protecting it from rain and salt spray. The rust-proof effect lasts for 3-6 months, making it particularly suitable for use in coastal areas or high-humidity regions. [Versatile Design] Compatible with exposed parts such as automotive exhaust pipes, hubcaps, and door handles. It can also be used on household hardware (such as faucets and bathroom accessories) and motorcycle electroplated parts. One spray for multiple uses, no repackaging required. [Convenient Application for Lazy People] Shake well and spray, no wiping required (let it evaporate on its own after 3 minutes), leaving no white mist residue. The reverse spray design precisely cleans uneven, and the ultra-fine nozzle saves on usage. One bottle can clean an entire vehicle's parts approximately 8-10 times. Package: 1 pcs Anti-rust polish 100ml
