Practical guide · Corrosion & restoration

How to free and restore seized or corroded equipment.

Seized components usually respond better to penetration, time and controlled movement than to brute force. The objective is to break the corrosion bond, flush loosened material and restore protection after the part is moving again.

At a glance

Penetration first. Force second.

Wet the corroded interface, allow time for penetration, work the component progressively and clean out the material that is released.

The objective

Break the corrosion bond without creating a second problem.

Rust and corrosion can lock together threads, pivots, shafts, linkages and other close-fitting metal surfaces. Forcing the component too early can round fasteners, bend linkages or damage castings.

The more controlled approach is to get penetrating oil into the corroded interface, give it time to work, introduce gentle movement, then continue flushing the loosened corrosion as movement returns.

Step by step

Work progressively from penetration to restoration.

Expose the corroded interface

Remove loose dirt and surface debris so the penetrating oil can reach the joint, thread, pivot or other area that has seized.

Apply enough product to wet the joint

Coat the affected metal and direct Breakout F-CLP into the corroded interface. For deep corrosion, allow time to soak rather than immediately applying maximum force.

Introduce gentle movement

Try controlled movement in both directions where the mechanism allows it. On robust components, light tapping can help disturb the corrosion bond, but avoid impact on fragile castings, precision parts or loaded mechanisms.

Repeat rather than force

If the part does not move, reapply and allow more penetration time. Several controlled cycles are preferable to one excessive attempt that damages the component.

Flush loosened corrosion

Once movement begins, keep working the part through an increasing range. Apply more product as needed so dissolved and loosened corrosion is carried out of the moving interface, wiping away the contaminated residue.

Clean and finish the restoration

Remove remaining external rust with an appropriate brush. If the equipment is being prepared for painting, clean off residual oil with hot soapy water as required and dry the surface completely before coating.

Relubricate and protect

When cleaning or painting is complete, apply the appropriate final lubricant or a light protective coating of Breakout F-CLP where suitable for the equipment and service conditions.

The result

Movement restored without stopping at the first success.

Freeing the component is only half the job. Removing released corrosion and leaving the correct lubrication or protective film helps prevent the same interface from quickly returning to a seized condition.
