Break free seized, rusted, and corroded fasteners with CRC Freeze-Off® — a super penetrant that uses an instant-freeze mechanism to do what ordinary penetrating oils can't. The moment it contacts the surface, the formula rapidly drops the temperature of the metal, causing the rust and corrosion to crack and contract. This thermal shock opens micro-fractures in the rust layer, letting the penetrant wick deep into threads and seized joints far more effectively than heat or standard penetrants alone.
Whether you're dealing with a frozen prop nut, a seized exhaust bolt, or corroded through-hull fittings that haven't moved in years, Freeze-Off® gives you a mechanical advantage before you even reach for a wrench.
- Instant-freeze action thermally shocks rust, cracking the corrosion layer on contact
- Penetrates deeper than standard penetrating oils for faster fastener release
- Works on seized bolts, nuts, fittings, cables, and corroded threads
- Effective on both ferrous and non-ferrous metals
- Fast-acting — reduces soak time needed compared to conventional penetrants
Parts Desk Insights
Best Use Case: Reach for Freeze-Off® when standard penetrants have already failed or when you need results fast. It excels on prop shaft nuts, exhaust manifold bolts, trailer hitch hardware, and any fastener that has been submerged or exposed to saltwater for extended periods. Apply generously, allow 5–10 minutes for the penetrant to wick into the joint after the freeze effect dissipates, then apply torque. For extremely stubborn fasteners, a second application combined with light impact often does the job. Keep a can in the toolbox for haul-out day — it’s one of the most-reached-for products when working on older hardware.
