Product Information
Full details
The WD-40 Specialist Silicone Lubricant is an ideal solution for DIY enthusiasts, mechanics, and homeowners who need to maintain equipment operating in challenging conditions. Its primary benefit is providing long-lasting, water-resistant lubrication that works on a variety of materials including plastic, rubber, and metal without leaving a sticky, dirt-attracting residue. While highly effective at protecting against rust and friction, users should note that the spray is designed for lubrication and light protection, and may not be the appropriate choice for heavy-duty metal-on-metal load-bearing applications that require specialized grease.

FAQs
Can I use this on bike chains?
While it provides lubrication, a dedicated bike chain lube is generally better for the high-pressure, high-wear environment of a bicycle drivetrain.
Is this product safe for electrical components?
It is not recommended for use on sensitive electrical contacts or circuits; use a dedicated contact cleaner for those applications.
Does this product stain fabrics?
It may leave a residue on porous fabrics; always cover nearby textiles before spraying.
How long does the lubrication last?
Longevity depends on the environment; indoor components may stay lubricated for months, while outdoor tools exposed to rain may require reapplication sooner.
Is it safe to use on car dashboard plastics?
It is safe, but it may leave a glossy finish; test on an inconspicuous area first to see if you like the look.
Troubleshooting
The spray nozzle is clogged.
Remove the nozzle and rinse it with warm water or use a pin to clear the orifice, then reattach.
Surface feels greasy after application.
You have likely applied too much; use a clean, dry rag to wipe away the excess lubricant.
The lubricant is not stopping a squeak.
Ensure the lubricant has reached the internal pivot point; if the metal is rusted, you may need a dedicated penetrating oil first.
Pros and Cons
Pros
- Does not attract dust or grime due to non-sticky finish
- Works reliably in extreme hot and cold temperatures
- Safe to use on rubber and plastic gaskets without causing degradation
- Provides effective water resistance for outdoor tools
- Convenient 3-pack ensures you have enough for multiple projects
Cons
- Not intended for heavy-duty pressure load-bearing surfaces
- Requires careful application to avoid overspray on floors (slip hazard)
- Not a substitute for dedicated rust-penetrating oils for stuck bolts
Setup, Compatibility & Care
To use, shake the can well before spraying. Apply a light, even coat to the target surface. If working in a tight area or needing precision, use the attached straw applicator. Wipe away any excess spray with a clean cloth to prevent slick surfaces on adjacent areas. Store the cans in a cool, dry place away from direct sunlight and temperatures exceeding 50 degrees Celsius. While the lubricant is safe for most surfaces, always perform a small spot test if applying to delicate plastics or painted finishes. For outdoor tools, clean off debris before applying the spray to ensure the barrier adheres directly to the metal or plastic surface.
