Advanced Mineral-Oil-Free Rust Solvent with Deep Capillary Action

A high-tech rust penetrant engineered for the toughest seized connections, using an innovative mineral-oil-free formula that infiltrates the smallest crevices through extreme capillary action. Unlike conventional rust busters, the dissolving power actually increases the longer it works - up to 24 hours - making it the go-to solution when standard penetrants have failed.

Extreme Penetration & Capillary Action

The innovative formula seeps into micro-crevices and thread gaps that conventional rust penetrants can't reach, actively dissolving rust to free seized connections from the inside out. Ideal for stubborn fasteners where surface application alone won't cut it.

Time-Activated Dissolving Power

Dissolving power increases with application time, delivering up to 24 hours of active rust-busting. For severely seized components, extended dwell times mean cleaner releases with less mechanical force - saving broken studs, stripped threads, and hours of drilling-out work.

Multi-Purpose Cleaning Performance

Beyond rust, the formula actively removes encrusted dirt, oil residue, resin, limescale, cement, soot, and oxidation deposits. Equally effective for cleaning rust film and stains from metal surfaces during restoration or detailing work.

Low-Friction Anti-Tilt Action

Low-friction active ingredients prevent threads from tilting or binding during removal - a common cause of snapped bolts on heavily corroded assemblies.

Safe for Components & Environment

Mineral-oil-free, biodegradable, and free from grease, resins, heavy metals, silicone, and AOX. Does not corrode conventional metal or rubber components in the engine bay, making it safe for use around seals, hoses, and sensitive assemblies.

Application Tip: For maximum results, apply liberally and allow extended dwell time - the longer it sits, the more rust it dissolves. On heavily seized fasteners, consider overnight application for the full 24-hour dissolving effect before attempting removal.
