Rustaway Multi-F 125ml

Penetrates & Loosens Rusted Nuts & Bolts
Low-viscosity penetrant chemistry drives deep into corroded thread interfaces via capillary action — breaking the electrochemical bond between rust-seized metal surfaces and freeing fasteners that have resisted manual torque. Effective on lightly corroded and severely seized fasteners alike, with dwell time scaled to corrosion severity.
Un-Jams Seized Mechanical Components
Penetrates into the micro-gaps of jammed hinges, linkages, cables, slides, and mechanical assemblies — dissolving corrosion and lubricating the contact surfaces to restore free movement without disassembly.
Lubricates & Protects Metal Surfaces
Leaves a thin, durable lubricating film on treated surfaces that reduces ongoing friction, prevents metal-on-metal wear, and provides a protective barrier against moisture, oxygen, and the environmental conditions that initiate corrosion.
Anti-Squeak Performance
Penetrates and lubricates the contact points of squeaking hinges, door mechanisms, suspension linkages, brake caliper slides, and cable guides — eliminating friction-induced noise immediately on application.
Displaces Moisture
Actively displaces water and moisture from metal surfaces, electrical contacts, battery terminals, and fasteners — interrupting the electrochemical corrosion process at its source and preventing rust initiation in moisture-exposed components.
Cleans Battery Terminals
Dissolves and clears the white sulphate and oxide deposits that form on battery terminals and clamps — restoring clean metal-to-metal contact for reliable electrical conductivity and eliminating the resistance-related starting and charging problems that corroded terminals cause.
Removes Adhesive & Sticker Residue
Solvent chemistry cuts through and lifts adhesive marks, sticker residue, tape backing, and label glue from metal and hard surfaces — cleaning cleanly and completely without abrasion or surface damage.
Speedy Action
Fast-acting penetrant begins working within minutes on light to moderate rust and corrosion — significantly reducing the waiting time and mechanical effort required to free seized components compared to conventional penetrating oils.
RoHS Compliant Formulation
Formulated without restricted hazardous substances — safe for use around modern vehicle electronics, ECU connectors, precision instruments, and sensitive electrical assemblies where conventional penetrating sprays pose contamination risks.

Work in a well-ventilated area. Keep away from open flames — aerosol propellant is flammable. For electrical applications, de-energise the circuit before application where possible.

1. Shake the can thoroughly before use to ensure the penetrant formulation is fully mixed and the propellant is activated.
2. Attach the precision extension tube to the nozzle for targeted, controlled delivery into thread gaps, hinge joints, and confined spaces.
3. Hold the can upright at all times during application — inverting the can interrupts propellant flow and delivers inconsistent spray output.
4. Position the nozzle a minimum of 30 cm (1 foot) from the target surface and apply in short, controlled bursts — directing the extension tube precisely at the rusted fastener thread, seized joint, or target component.
5. For rusted nuts, bolts, and fasteners: apply directly to the thread interface and allow the penetrant to dwell. For light to moderate rust, allow 3–5 minutes for the penetrant to wick into the thread and begin dissolving the rust bond before applying torque.
6. For heavily corroded or severely seized fasteners: allow a longer dwell time of 15–30 minutes, or apply a second coat after the initial dwell period — allowing additional time between applications for the penetrant to progressively work deeper into the rust layer. Repeat as necessary until the fastener moves freely.
7. For squeaking hinges, linkages, and mechanical joints: spray directly at the pivot point or contact zone and work the component through its range of motion immediately after application to distribute the lubricant evenly through the joint.
8. For battery terminals and electrical contacts: apply at the prescribed distance and allow to dry fully before reconnecting or re-energising.
9. For adhesive residue: apply to the residue, allow 1–2 minutes of dwell time, then wipe clean with a soft cloth.
10. Pro Tip: Apply Rustaway Multi-F to wheel nuts, chassis fasteners, and suspension bolts as a preventive treatment at every service interval — particularly on vehicles operating in coastal, monsoon, or high-humidity environments. A single preventive application dramatically reduces the risk of fastener seizure at the next service and eliminates the risk of rounded or broken fasteners during future maintenance.

Q: What does RoHS compliant mean for Rustaway Multi-F?
RoHS (Restriction of Hazardous Substances) compliance means Rustaway Multi-F is formulated without restricted hazardous substances including lead, mercury, cadmium, and certain flame retardants. This makes it safe for use around modern vehicle electronics, ECU connectors, and precision electrical assemblies where conventional penetrating lubricants containing restricted substances pose contamination risks.

Q: How long should I leave Rustaway Multi-F on a rusted bolt before trying to remove it?
For light to moderate rust, allow 3–5 minutes of dwell time before applying torque. For heavily corroded or severely seized fasteners, a dwell time of 15–30 minutes is recommended — with a second application after the initial dwell for the most stubborn cases. The penetrant continues to work deeper into the rust layer throughout the dwell period.

Q: Can Rustaway Multi-F be used on car door hinges to stop squeaking?
Yes. Rustaway Multi-F is specifically effective on squeaking door hinges, bonnet hinges, boot hinges, and mechanical linkages — the anti-squeak penetrant lubricates the pivot contact points and eliminates friction-induced noise immediately on application.

Q: Is Rustaway Multi-F safe to use on electrical components and battery terminals?
Yes. Its RoHS-compliant, moisture-displacing formulation makes it safe for use on battery terminals, electrical connectors, and exposed wiring contacts. De-energise the circuit before application where possible and allow full evaporation before reconnecting.

Q: Can Rustaway Multi-F remove sticker and adhesive residue from car bodywork?
Yes. The solvent chemistry in Rustaway Multi-F dissolves adhesive marks, sticker residue, and label backing from metal and hard surfaces cleanly. Apply, allow a brief dwell, and wipe clean with a soft cloth. Test on an inconspicuous area first on painted surfaces to confirm compatibility with the specific paint or clear coat finish.

Q: How is Rustaway Multi-F different from standard penetrating oils like WD-40?
Rustaway Multi-F is a multi-functional RoHS-compliant formulation engineered specifically for automotive and modern vehicle maintenance applications — combining penetrant, lubricant, moisture displacer, anti-squeak, and surface protectant functions in a single product. Its RoHS compliance and compatibility with modern vehicle electronics distinguishes it from conventional penetrating oils that may contain restricted substances incompatible with sensitive electronic assemblies.
