Grease Spray WD-40 Specialist Spray Grease 400 ml — long-lasting lubrication for mechanisms

WD-40 Specialist Spray Grease 400 ml is an aerosol lubricant formulated to provide long-lasting lubrication and protection for metal parts and moving mechanisms. The spray delivers an even, clingable grease film that reduces friction, wear and noise on hinges, bearings, gears and sliding surfaces. Designed for maintenance, repair and both industrial and domestic applications, this spray grease is intended for situations where durable, residual lubrication is required without the need for messy hand-applied greases.

Advantages

This spray grease forms a durable film that resists water wash-off and helps protect against corrosion while reducing metal-to-metal contact. The aerosol format allows controlled, targeted application in hard-to-reach areas and on small components. The product is suitable for repeated use in routine maintenance, providing consistent lubrication and quieter operation of moving parts.

Suitable for

• Hinges, door mechanisms and cabinet hardware
• Wheel bearings, small bearings and bushings
• Gears, sprockets and sliding rails
• Tools, hinges and outdoor equipment exposed to moisture
• Preventive maintenance in workshops and home repair tasks

When it may not be suitable

This spray grease is formulated for metal parts and moving mechanisms; it is not intended for use on precision instruments requiring specialized lubricants, plastics that are incompatible with petroleum-based greases, or electrical contacts where non-conductive, dielectric lubricants are required. It may be less suitable where extremely high-temperature lubrication or food-grade certification is needed.

Key specifications

• Form: aerosol spray with grease-based formulation
• Net volume: 400 ml
• Primary function: long-lasting lubrication and protection
• Suitable surfaces: metal components, bearings, gears, hinges, sliding surfaces
• Performance features: water resistance, corrosion protection, noise reduction

How to use

Shake the can well before use. Hold the nozzle 15–25 cm from the target surface and apply a thin, even layer of spray grease to the moving parts or contact surfaces. For best results, clean away dirt, old grease and contaminants before application. Allow the lubricant to settle and penetrate for a short time; wipe away any excess to prevent attracting dust. Reapply as part of routine maintenance or when lubrication performance diminishes.

What to consider before purchase

• Confirm compatibility with plastics, rubber or painted surfaces in the application area.
• Ensure the lubricant's temperature range meets operating conditions for your equipment.
• Check whether a food-grade or electrically non-conductive lubricant is required instead.
• Consider if an aerosol format is practical for the locations where you need to apply grease.

Usage recommendations

For durable results, use WD-40 Specialist Spray Grease on clean surfaces and schedule reapplication based on operating conditions. Avoid over-application to prevent buildup; a light, even film typically provides the best balance of protection and cleanliness.
