How to Use

1. Spray on and allow to penetrate for no more than 30–60 seconds, then wipe with a dry cloth. Do not allow it to dry on the surface.
2. For heavy rust on metal surfaces, scrub with a Scotch-Brite™ pad. Heavier rust may require multiple applications.
3. After use, wash the area with a mixture of soap and water.

Caution: Rust Free™ is acidic and can cause dulling on polished surfaces. Always test in a small, inconspicuous area first. Avoid use on concrete, guns, black oxide tools, corroded aluminum, and kitchen utensils or cookware (it is not FDA approved). On cast iron, apply to a rag and wipe rather than spraying directly, to prevent white spotting; rinse with soap and water after use.
