Gal Rust Treatment, Liquid, 1-gallon Jug

Ospho is a rust-inhibiting coating that chemically converts iron oxide (rust) to iron phosphate, stopping corrosion at its source. This liquid rust converter penetrates deep into rusted areas on steel, iron, and other metal surfaces, dissolving existing oxidation while creating a durable, paint-ready protective layer. The fast-acting phosphoric acid-based formula works in both indoor and outdoor environments, making it ideal for workshops, construction sites, automotive repair, and DIY projects where metal protection is essential.

By converting rust into a stable, inert coating, Ospho reduces the need for frequent re-applications and eliminates the hassle of sanding or scraping corroded surfaces. The resulting hard, dark finish seals the metal and prepares it for painting or additional coating, extending the lifespan of tools, equipment, machinery, fences, and household metal items while saving time and money on maintenance.

Features and Benefits
