Penetrating Rust Remover & Release Agent | NZ

The Wurth Rust Remover Rost-Off is a high-performance penetrating spray designed to break down rust, free seized fasteners, and protect metal components against further corrosion. When bolts won’t budge and parts are locked solid, this is what you reach for.

Used daily in automotive and industrial workshops across New Zealand, Rost-Off creeps deep into rusted threads and tight joints, reducing the force needed to loosen parts and helping prevent damage during disassembly. It also leaves a protective film to slow down future corrosion.

It’s a proper workshop essential for teardown, repairs, and preventative maintenance.
