The WD-40 Specialist Contact Cleaner 300ml is a high-performance cleaning solution engineered to maintain the reliability of sensitive electrical and electronic equipment. This specialized spray effectively removes oil, dirt, flux residue, and condensation, which are common causes of electrical malfunctions. Its non-conductive and fast-drying formula ensures that delicate components are cleaned thoroughly without leaving any residue behind, making it an essential maintenance tool for both professional and home use.

Advantages

This contact cleaner offers excellent compatibility with a wide range of materials, including most plastics, rubbers, and metals, allowing for versatile application without the risk of surface damage. The fast-drying nature of the product minimizes downtime during maintenance, while its non-conductive properties provide an added layer of safety when working on energized equipment. By effectively eliminating contaminants, it helps restore electrical conductivity and prevents future failures in complex electronic systems.

Suitable for

• Circuit boards and printed circuit assemblies
• Electrical switches and relays
• Connectors and contact points
• Electronic control units and sensors
• Precision instruments and laboratory equipment

When it may not be suitable

This product is not intended for use on high-voltage power lines or heavy-duty industrial machinery where specialized dielectric fluids are required. It should not be used on surfaces that are extremely hot, as the solvent may evaporate too quickly or pose a flammability risk.

Key specifications

• Volume: 300 ml
• Formula: Non-conductive and residue-free
• Drying time: Fast-drying
• Compatibility: Safe for most plastics, rubbers, and metals

How to use

Before application, ensure that the power supply to the equipment is disconnected to prevent short circuits. Shake the can well and hold it in an upright position. Spray the product directly onto the component from a distance of approximately 15 to 20 centimeters. Allow the solvent to penetrate and dissolve the contaminants. The fast-drying formula will evaporate quickly, leaving the surface clean and dry. For stubborn deposits, a soft brush may be used to assist in the cleaning process before applying a final spray.

What to consider before purchase

• Verify that the equipment is compatible with solvent-based cleaners
• Ensure the area is well-ventilated during use
• Check that the power source is fully disconnected

Usage recommendations

Always test the product on a small, inconspicuous area of the material before full application to ensure compatibility. Store the canister in a cool, dry place away from direct sunlight and heat sources.
