Product information & specifications
Swarfega Duck Oil Multi-Purpose Service Spray - Silicone-Free Non-Conductive Lubricant
Swarfega Duck Oil (500ml aerosol, part number SDO500ML) is one of the UK's most widely used multi-purpose service sprays — a silicone-free, non-conductive, mineral-oil-based spray that penetrates, lubricates, protects and displaces water across virtually any surface without the need to dismantle machinery or components. Its exceptionally low surface tension allows it to penetrate tight tolerances and reach areas that conventional lubricants cannot. Used across workshops, construction sites, gardens and vehicle maintenance, it releases seized nuts, bolts and components, lubricates metal and moving parts, insulates and dries damp electrics, starts engines in wet conditions, and forms a protective seal against rust and corrosion for up to 12 months. The silicone-free formulation makes it safe to use in areas where subsequent paint or surface coating application is planned. 1 litre covers approximately 20m². Also available in a 5L container for regular users. In stock at Gustharts with fast UK delivery.
Swarfega is one of the UK's most recognised industrial maintenance brands, now part of SC Johnson Professional. Duck Oil has been a staple of professional workshops and maintenance teams across construction, automotive, forestry and groundscare for decades.
Key Features
- Silicone-free formula — reduces contamination risk on surfaces prior to painting or surface coating; safe for use in paintshop environments
- Non-conductive with high dielectric strength — insulates electrics; can be safely used on all types of electrical equipment without impairing performance or causing short circuits
- Exceptionally low surface tension — penetrates into tight tolerances, crevices and corroded threads where standard lubricants cannot reach without dismantling
- Releases seized parts — penetrates corroded threads to free seized nuts, bolts and components quickly
- Displaces water and dries damp electrics — restores electrical continuity on wet ignition systems, motors and connections
- Damp starter — spray onto the ignition and electrical components of engines struggling to start in wet conditions
- Light lubricant — leaves a thin lubricating film on metal surfaces, moving parts and mechanisms
- 12-month rust and corrosion protection — forms a protective seal on metal parts extending service intervals and preventing surface degradation
- Light degreaser — removes light contamination and surface grime from metal components
- Versatile application — apply by spraying, dipping or brushing; remove by wiping with a cloth or dipping in a solvent degreaser
- No dismantling required — low surface tension penetration means it works directly on assembled components in situ
- 1 litre covers approximately 20m² — economical for regular workshop and site use

Also Known As
Swarfega Duck Oil is also referred to as a penetrating oil, maintenance spray, release oil, freeing oil, anti-corrosion spray, light machine oil, water-displacing lubricant, multi-purpose lubricant, workshop spray, service oil and damp start spray. It is a direct alternative to WD-40 and similar multi-purpose penetrating sprays, with the key difference being its silicone-free formulation and confirmed high dielectric strength — making it particularly suitable for electrical components and paintshop-adjacent work where silicone contamination is a concern. For ordering, reference SDO500ML (500ml) from Gustharts.
Often Used Alongside
- Sharpening and maintenance tools — Duck Oil is a practical addition to any chainsaw, brushcutter or hedge trimmer maintenance kit for treating bolts, bar fixing screws and exposed metal components
- STIHL spare parts — use Duck Oil on seized fasteners and corroded fixings when servicing STIHL machinery

FAQs
Is Swarfega Duck Oil safe to use on electrical components?
Yes. Duck Oil is non-conductive with a high dielectric strength, meaning it insulates rather than conducts electricity. It can be used safely on all types of electrical equipment, ignition systems and electrics without impairing performance or causing short circuits.
Why does it matter that Duck Oil is silicone-free?
Silicone contamination is a known problem when spraying near surfaces that will later be painted or coated — silicone causes fish-eye defects and adhesion failures. Duck Oil's silicone-free formula eliminates this risk, making it safe to use in paintshops and on components that will be painted or coated after treatment.
How long does Duck Oil protect against rust?
Up to 12 months. The mineral-oil base forms a thin protective seal on metal surfaces that resists moisture and oxygen ingress, providing corrosion protection for the duration specified under normal conditions.
Can Duck Oil start an engine in damp conditions?
Yes. Spraying Duck Oil onto damp ignition components, HT leads, spark plug caps and electrical connections dries the moisture and restores electrical continuity, helping engines start that are struggling due to wet conditions.
How is Duck Oil different from WD-40?
Both are multi-purpose penetrating lubricants. Duck Oil's key differentiators are its silicone-free formulation (safe near paint and coatings) and its confirmed high dielectric strength (specifically non-conductive on electrics). WD-40 contains silicone and its electrical safety is less clearly defined for all applications.
