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 noisy baseboard heaters.  And here is what we discovered about this versatile product.

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. It is ideal for use on our heaters. It also works well on the hinges on our outdoor porch screen doors, shed doors, and 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. Yes, many treadmills have a permanently lubed belt and platform. Yet some older ones may squeak and stall, needing a little silicone spray on those surface. This spray will indeed quiet down a treadmill. But if the treadmill original lube is failing, then we would just replace the belt. New belts typically come pre-lubed. So they’d probably last longer than an old one with this stuff on it.

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

You can easily adjust the angle of the spray discharge.

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. This, according to the web site, waterproofs and protects metal, rubber, vinyl, and plastic.  Thus this is a highly versatile, one-stop lubricant which works on 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. This smell really comes out when you apply it to surfaces that subsequently become hot. Example: In electric baseboard heaters.  So we suggest using this product only in well-ventilated areas. Also, to cut odor, let it completely dry before working the treated devices.

A bit Expensive

We paid $5.79 for a can of WD-40 silicone, when we expected to pay $3 or $4 dollars.  In other words, this product seems a bit pricey. But this is no doubt due to the WD-40 name. However, if less of it still does the job, then 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.

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 do not store this product close to sources of ignition or heat.

Our Rating

On the whole, we like this spray lubricant, except for its strong odor.  We find it effective and durable in so many places. Though it costs on the high-side of fairly, we don’t mind paying, due to the great performance. So we’d rate this product at 91 out of 100.

Where To Buy WD-40 Specialist Silicone Spray

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.
