WD-40 Specialist Silicone Spray Lubricant Review

WD-40 products have adorned our workshop shelves for years.  Here, we review the WD-40 Specialist silicone spray lubricant that’s been around for some years now.  Works well on treadmills, door hinges, bike chains, and a slew of other applications.

Recently we brought home an eleven-ounce can of WD-40 Specialist Silicone Lubricant Spray to  quiet my noisy baseboard heaters,  and here is what we discovered about this versatile product WD40.





Benefits, Features. Pros, and Advantages of WD-40 Specialist Silicone Spray

Withstands High Heat

This spray lube is a high-temperature, moisture resistant spray-on lubricant, which made it ideal for use on my heaters as well as the hinges on my outdoor porch screen doors, shed doors, and squeak wheelbarrow wheels.

Water Resistant

Under normal exposure conditions to water, this silicone lube does not wash off quickly.

Great Treadmill Belt Lube

WD-40 is safe for all rubber parts.  Though many treadmills feature a permanently lubricated belt and platform, some older ones may squeak and stall, needing a little silicone spray on the platform surface.  While this spray will get you out of a pinch on a treadmill, we recommend that if you feel that your treadmill needs lubed, then you should probably just replace the belt.  New belts typically come pre-lubed.

Reverses Rust Effects

Some of my tools were rusty due to days-long submergence in dirty flood waters back in 2004.  But this spray restored many of them to proper operation.  My needle-nosed and diagonal pliers became much easier to open and close after application of the WD-40 silicone spray-on lube.

Attached Spraying Straw

The spray tube comes built onto the can, which is nice because I’m always losing these tubes from other products.





Aiming Nozzle

The angle of the spray discharge can easily be adjusted on the can tops of this and the rest of the WD-40 Specialist line of lubricants, penetrators, and protectors.

Quick Drying Formula in WD-40 Specialist Silicone Spray

After application this silicone lubricant dries in less than a minute in my experience.  So you needn’t wait long to begin using your so-lubricated appliances.

Colorless Silicone Coating Left Behind

Indeed, this product leaves little behind, except a slippery clear film that, according to the web site, waterproofs and protects metal, rubber, vinyl, and plastic.  Thus this is a highly versatile, one-stop lubricant which is applicable to many household surfaces.

Quick Cleanup

I’ve found clean-up to be a snap.  You just wipe any excess lubricant away with an absorbent cloth.

Disadvantages, Cons, Problems, and Limitations of WD-40 Specialist Silicone Spray

Strong Smell

This spray lubricant has a very strong odor; particularly when you initially apply it to surfaces that subsequently become hot, as in my electric baseboard heaters.  So I’d recommend using the WD-40 Silicone Lubricant only in well-ventilated areas.  Also, to minimize odor, allow it to completely dry before working the devices to which you’ve applied it.

A bit Expensive

I paid $5.79 for my can of WD-40 silicone, when I was expecting to pay $3 or $4 dollars.  In other words, I deem this product a bit pricey, no doubt due to the WD-40 name affixed to it.  However, if I need apply it less than the more traditional greases and oils, perhaps the extra cost is worth it.





Separates Quickly

You should shake the can profusely before applying, as the silicone often separates from the propellant.

WD-40 Specialist Silicone Spray Contains Flammable Gasses

And, speaking of propellants, the label says that WD-40 Silicone lube employs a highly flammable butane-based compound as its propellant.  Hmmm.  Seems like they could have used a less volatile gas.  So great care must be taken not to store this can close to sources of ignition or heat.

Our Rating for WD-40 Specialist Silicone Lubricant Spray

On the whole, I’m pleased with this spray lubricant, except for its pungent odor.  I’ve found it to be effective, durable in many applications, and though priced on the high-side of fairly, I didn’t mind paying this due to the importance of the job I required it for.  I’d rate this product at 91 out of 100.

Where To Buy WD-40 Specialist Silicone Spray Lubricant

Look for the black, silver, and white can with the blue and yellow WD-40 logo.  This is a useful chemical to keep around the house, for sure.  Find it at Lowes, Home Depot, Amazon, and others.
