CRC 5-56 500 ml – Multi-Purpose Penetrating Lubricant and Corrosion Protection Spray
CRC 5-56 500 ml is a versatile multi-purpose maintenance spray designed for lubrication, penetration, moisture displacement and corrosion protection. It helps loosen seized bolts, nuts and mechanical components while leaving a thin protective film on metal surfaces.
The product combines four important functions: penetrates, displaces moisture, lubricates and protects against corrosion. It is suitable for industrial maintenance, automotive workshops, equipment servicing and everyday repair work.
Applications
- Seized bolts and nuts – helps release connections affected by rust, dirt or dried grease.
- Hinges and moving mechanisms – reduces friction and squeaking.
- Metal component protection – forms a thin film that helps prevent moisture-related corrosion.
- Ignition systems – helps displace moisture from suitable components when electrical power is disconnected.
- Industrial maintenance – supports servicing and releasing mechanical components.
- Tools and workshop equipment – provides temporary corrosion protection during storage.
- Garden equipment – suitable for general maintenance of metal mechanisms.
Key Features and Benefits
- High penetrating ability – reaches difficult areas and helps loosen corroded or seized components.
- Moisture displacement – drives water away from treated surfaces.
- Corrosion protection – leaves a thin protective film on metals and alloys.
- Lubricating action – helps reduce friction in moving mechanisms.
- Versatile performance – suitable for a wide variety of servicing and maintenance tasks.
- Precise application – supplied with an extension tube for difficult-to-reach locations.
- 95% active product content – achieved through the use of a CO2 propellant.
Directions for Use
- Read the product label and safety data sheet before use.
- Disconnect electrical power before treating electrical equipment.
- Apply a thin, even film to the surface requiring lubrication or protection.
- For seized fasteners, direct the spray towards the joint between components.
- Allow several minutes for the product to penetrate.
- Repeat the application if necessary.
- Remove excess material with a suitable cleaning cloth or cleaning product.
Selection Advice and Limitations
CRC 5-56 is a general-purpose maintenance lubricant intended for lubrication, penetration and temporary corrosion protection. It is not a replacement for specialised bearing grease, heavy-duty gearbox lubricants or oils specified by equipment manufacturers.
Although compatible with most common plastics, rubbers and coatings, the product should be tested before use on sensitive or stressed materials. Do not spray onto energised electrical equipment.

Frequently Asked Questions
Can CRC 5-56 loosen rusty bolts?
Yes. Its penetrating action helps release fasteners affected by rust, dirt or dried grease. However, it is not designed to chemically remove all rust from metal surfaces.
Is CRC 5-56 suitable for door hinges?
Yes. It helps reduce friction and eliminate squeaking in hinges and other lightly loaded moving mechanisms.
Does CRC 5-56 displace moisture?
Yes. Moisture displacement and protection against water are among its primary functions.
Does it protect metal against corrosion?
Yes. It leaves a thin protective film that provides temporary corrosion protection on treated metal surfaces.
Can CRC 5-56 be used on electrical components?
It can help displace moisture from suitable ignition-system components. Never apply the product to energised equipment. Ensure safe conditions before reconnecting power.
Is it compatible with plastics and rubber?
According to the manufacturer, it is compatible with most common plastics, rubbers and coatings. Always test sensitive or stressed materials before use.
