ACF-50 Anti-Corrosion Spray (13 oz Aerosol)
Updated June 9, 2026
ACF-50 is a corrosion-inhibiting compound designed for use on all metals and electrical systems. It applies as a clear, ultra-thin fluid film that neutralizes existing corrosion and prevents new rust from forming. Commonly used on automotive, motorcycle, and aircraft components, it can be sprayed directly into connectors and switches to prevent electrical failures.

How It Works
ACF-50 uses a unique formula that deposits a microscopic, non-greasy barrier on metal surfaces. This film acts as an "off switch" for corrosion by chemically neutralizing the corrosive effects of road salt, moisture, and other contaminants. The treatment remains active for up to 24 months and does not dry out, trap moisture, or contain solids. It is non-flammable and non-toxic, making it safe for use on a wide variety of components.
Common Failure Symptoms It Addresses
Corrosion-induced electrical failures are a primary target—intermittent connections, relay and switch malfunctions, and corrosion in multi-pin connectors can all be prevented or reversed with ACF-50. It also frees seized nuts, bolts, and screws that have rusted in place, and protects exposed metal parts on vehicles and equipment from rust and pitting.
Installation Notes
Apply to clean, dry surfaces for best adhesion. Spray directly into electrical connections, microswitches, cannon plugs, and relays. ACF-50 is safe on paint, plastics, rubber, and all metal types. Avoid contact with brakes, rotors, and tires. Reapply every 12 to 24 months depending on exposure conditions. Shake well before use.
