Hand tools are essential investments for machinists, mechanics, and maintenance professionals. Exposure to humidity, moisture, and improper storage can cause corrosion, especially on unprotected steel surfaces. WD-40 Multi-Use Product can help protect suitable metal tools by leaving a moisture-resistant film.

How to use it: Clean and dry the tool, apply a light coating where appropriate, and wipe away excess product. Store tools in a dry, suitable environment. For precision measuring instruments such as micrometers and calipers, follow the manufacturer's instructions to avoid affecting measuring surfaces or accuracy.

3. Lubricate Suitable Hinges and Moving Mechanisms

Squeaking hinges, stiff access panels, and difficult-to-operate mechanisms are common maintenance problems. WD-40 Multi-Use Product can help lubricate suitable hinges and linkages, reducing friction and eliminating certain squeaks. Components exposed to heavy loads, extreme temperatures, or continuous operation may need a dedicated lubricant with specific performance characteristics.

Workshop tip: Identify the cause of friction first. Dirt buildup, worn components, and misalignment may call for cleaning, adjustment, or repair rather than lubrication alone.

4. Displace Moisture From Suitable Metal Components

Moisture can accelerate corrosion on exposed metal parts, particularly in humid environments or facilities where condensation is common. WD-40 Multi-Use Product helps displace moisture and protect suitable metal surfaces, provided the product is approved for the application.

Important: Do not spray the standard product indiscriminately into energized electrical equipment. Follow the equipment manufacturer's instructions and use a suitable electrical contact cleaner when the application requires one.

5. Remove Certain Grease, Grime, and Adhesive Residues

Workshop tools and equipment can accumulate oil, grime, and sticky residue. WD-40 Multi-Use Product can help loosen certain contaminants and adhesive residues on compatible surfaces. Apply a small amount, check material compatibility, and wipe clean using an appropriate cloth. For heavy industrial contamination, a dedicated degreaser or parts-cleaning solution may be more appropriate.

This matters especially when surfaces will subsequently be painted, welded, bonded, or used in precision assembly.

6. Protect Metal Components During Storage

Metal parts awaiting assembly, shipment, or installation may be vulnerable to corrosion during storage. WD-40 Multi-Use Product may suit selected short-term protection applications. For longer storage periods or demanding environments, a dedicated corrosion inhibitor can offer more appropriate protection.

WD-40 Specialist Corrosion Inhibitor is designed to protect suitable metal components against corrosion, including in damp storage conditions. Browse WD-40 products at Penn Tool Co. Verify the required protection period, surface compatibility, and subsequent cleaning requirements before choosing a corrosion inhibitor.

7. Maintain Facility Hardware and Outdoor Equipment

Manufacturing businesses maintain more than production machinery. Doors, latches, gates, hinges, hand tools, and outdoor fixtures also need regular attention. WD-40 can help loosen certain stuck mechanisms and protect compatible metal surfaces against moisture-related corrosion. For chains, cutting blades, and specialized equipment, use the lubricant recommended for that particular component.

8. Lubricate Suitable Sliding Tracks and Rollers

Sliding mechanisms can become difficult to operate because of dirt, corrosion, or inadequate lubrication. WD-40 Multi-Use Product may help with compatible mechanisms, but it is not always the best choice for tracks that collect substantial dust. WD-40 Specialist Dry Lube is designed to leave a lubricating film that resists dirt and dust buildup, making it worth considering for suitable slides, rollers, and door or window tracks.

Best suited for: Maintenance teams, equipment installers, and workshops where cleanliness matters. Explore WD-40 Specialist Lubricants at Penn Tool Co.

9. Support Routine Maintenance of Power Tools

Power tools face dust, debris, and demanding working conditions. WD-40 may help protect compatible external metal surfaces and loosen certain residues during routine maintenance. Disconnect the power source and follow the manufacturer's instructions before cleaning or servicing a tool.

Do not spray standard WD-40 into a motor, switch, battery compartment, or electrical assembly unless the manufacturer explicitly permits it.

10. Maintain Suitable Metal Fixtures and Fasteners

Industrial facilities contain many small metal components that need periodic attention, including brackets, latches, fasteners, and access-panel hardware. WD-40 can help loosen certain stuck fasteners and protect compatible metal hardware against corrosion. A structured preventive maintenance routine helps catch minor problems before they interfere with equipment operation.

For structural fasteners, safety-critical assemblies, and precision machinery, follow the prescribed maintenance procedure.

11. Help Prepare Compatible Surfaces for Maintenance

Before maintaining metal equipment, technicians may need to remove surface grime, loosen deposits, or address light contamination. WD-40 can assist with selected preliminary cleaning tasks, depending on the material and type of contamination. It is not a universal rust remover or a substitute for proper surface preparation.

If a component needs to be painted, welded, bonded, or coated, remove incompatible residues and prepare the surface according to the requirements of the next process.

12. Support a More Effective Preventive Maintenance Routine

The most valuable application of WD-40 may be its role in a broader maintenance strategy. Regularly inspecting tools, cleaning compatible components, protecting metal surfaces, and addressing minor mechanical problems can help reduce avoidable maintenance interruptions.

WD-40 can support selected tasks within that routine, but it cannot replace scheduled servicing, equipment inspections, or the correct lubricants for critical machinery. The goal is to identify the problem, choose the right product, and apply it according to the manufacturer's instructions.

WD-40 Multi-Use Product vs. Specialist Lubricants: Which Should You Choose?

One common workshop mistake is assuming that every lubricant performs the same function. Different formulations are designed for different requirements. The correct choice depends on load, temperature, moisture exposure, dust accumulation, material compatibility, and equipment specifications.

WD-40's Specialist range includes products formulated for more specific maintenance requirements. Consult the product documentation and equipment manufacturer's recommendations before selecting a formulation.
