WD-40 Multifunctional Lubricant Aerosol 400ml

WD-40 Multifunctional Lubricant Aerosol 400ml is a versatile maintenance solution designed to address a wide variety of mechanical and household challenges. This high-performance spray is engineered to penetrate tight spaces, displace moisture, and provide a protective barrier on metal surfaces. Whether you are dealing with stubborn rusted parts or looking to ensure the smooth operation of moving components, this aerosol provides reliable results in automotive, industrial, and domestic environments.

Advantages

The primary benefit of this lubricant is its ability to perform multiple functions in a single application. It effectively loosens seized or rusted fasteners, allowing for easier disassembly of components. By displacing moisture, it helps prevent electrical short circuits and protects metal parts from oxidation and corrosion. Its lubricating properties reduce friction in moving parts, which helps to extend the lifespan of tools and machinery while ensuring they operate quietly and efficiently.

Suitable for

• Loosening rusted nuts, bolts, and screws
• Lubricating hinges, locks, and sliding mechanisms
• Displacing moisture from electrical contacts and ignition systems
• Protecting metal tools and equipment from rust and corrosion
• Cleaning grease, grime, and adhesive residues from surfaces

When it may not be suitable

This product is not intended for use as a long-term heavy-duty lubricant for high-load industrial bearings or high-temperature environments where specialized greases are required. It should also be avoided on certain delicate plastics or rubbers that may be sensitive to petroleum-based solvents.

Key specifications

• Volume: 400 ml
• Application method: Aerosol spray
• Function: Lubricant, penetrant, moisture displacer, and corrosion inhibitor
• Surface compatibility: Metal and various non-porous materials

How to use

To use the WD-40 aerosol, shake the can well before application. Hold the can upright and spray directly onto the target area from a distance of approximately 15 to 20 centimeters. For precise application in hard-to-reach areas, use the attached straw. Allow the product to penetrate for a few minutes if you are working on rusted or seized parts. Wipe away any excess liquid with a clean cloth if necessary.

What to consider before purchase

• Ensure the surface is compatible with petroleum-based lubricants
• Check if the area requires a specialized high-temperature or high-pressure grease instead
• Consider the ventilation of the workspace during application
• Verify if the 400ml volume is sufficient for your intended frequency of use

Usage recommendations

For optimal results, apply the lubricant to clean surfaces whenever possible. When treating rusted components, allow sufficient time for the product to penetrate the threads before attempting to loosen them. Always test on a small, inconspicuous area if you are unsure about material compatibility.
