Best Nonstick Sprays for Snow Blowers Comparison Chart

Our Top Picks

We selected each of the following best nonstick sprays for snow blowers based on performance, ease of use, and overall value. 

Best Overall

DuPont Snow & Ice Repellent Nonstick Clear

See It

What We Like

• Lasts through multiple uses
• Prevents clogged chutes; keeps auger clear
• Creates a slick surface so snow is thrown further

What We Don’t Like

• Surfaces need occasional wiping so dirt doesn’t stick
• Flammable; bottle can burst in hot conditions

Specs

• Volume: 10 ounces
• Drying time: 10 minutes
• Functions: Safe for use on metal, rubber, and plastic

The DuPont Teflon snow and ice repellent spray is specifically made to create nonstick surfaces that repel moisture in liquid or frozen form. The Teflon fluoropolymer and silicone combination adheres well to metal, rubber, or plastic, creating a barrier between those materials and snow and ice that would otherwise cause chute clogging and auger buildup. 

As with any nonstick spray, the product adheres best when the surface it’s applied to is dry. After wiping down our snow blower’s chute and auger, we sprayed on a consistent coating of the Teflon snow and ice and left everything to dry. We periodically pressed a finger against the sprayed surface to test for readiness, and after about 10 minutes, the coating was completely set. During the long snow-clearing session that followed, the chute didn’t clog once and the coating had plenty of coverage remaining to handle the next storm.

What our tester says: “When testing this spray with our snow blower, we were careful to hit a combination of powder and a few slushy patches that would usually be difficult for the chute to clear. The powder flew through the snow blower chute without issue, and the wet snow did as well.”—Zach Lazzari, Product Reviews tester and writer

Runner-up

Liquid Wrench Silicone Spray

See It

What We Like

• Easy to apply and dries with clear finish
• Works on a wide range of household items
• Unlikely to become gummy

What We Don’t Like

• Flow is hard to control during delicate applications

Specs

• Volume: 11 ounces
• Drying time: 10 to 15 minutes
• Functions: Safe for use on metal, rubber, plastic, and wood; inhibits rust

Liquid Wrench silicone spray for snow blowers is an aerosol spray with a heavy silicone base that sticks well to slick surfaces to provide optimum nonstick performance. Since silicone is a natural water repellent, it works for everything from creating a waterproof barrier to fixing squeaky hinges and inhibiting rust. 

For snow blowing specifically, this Liquid Wrench spray proved to be an excellent lubricant: While running through a walkway and driveway covered in wet snow, the chute remained clean and didn’t clog once. It’s also a great product for keeping your snow blower or snow plow lubricated and dry as part of your off-season maintenance plan. 

The dry time for this particular snow blower silicone spray was just a bit longer than that of our top choice, and we liked that it left a clear finish with no residue. Since this option is also safe for use on wood, we added it to some squeaky oarlocks on our boat once we’d wrapped up the rest of our tests.

Best Bang For The Buck

DuPont Nonstick Dry Film Lubricant

See It

What We Like

• Creates a mess-resistant coating
• Helps protect metal augers and surfaces
• Works in exceedingly cold temperatures

What We Don’t Like

• Can stain clothes and other soft materials
• Has a strong smell

Specs

• Volume: 10 ounces
• Drying time: 10 to 15 minutes
• Functions: Safe for use on metal, rubber, plastic, and wood; dirt-, grit-, and grime-resistant

This dry film aerosol lubricant is another excellent nonstick snow blower spray from DuPont. It’s formulated using ceramic technology that helps it adhere especially well to metal surfaces, making it ideal for snow blowers with steel augers and metal chutes. DuPont claims this spray works for up to 4 weeks, but that depends on the frequency of snow blower use and how much abrasion it experiences. It’s probably best to reapply after a week or so to ensure the snow blower’s surfaces remain protected. 

In our tests, this spray was plenty slick, but it was not quite as effective as our top two options. It endured abuse when tested on a gravel driveway, and we were happy to see no residue or attached dirt left on our machine. Ultimately, this nonstick spray was durable, easy to apply, and performed well. And with most retailers offering it for just over $10 for a 10-ounce can, it’s a great value.

Best Heavy-Duty

CRC Heavy-Duty Silicone Lubricant

See It

What We Like

• Delivers a nice, even spray
• Highly recommended by trade professionals
• Works on most materials

What We Don’t Like

• Prevents sticking but not exceptionally slick

Specs

• Volume: Various sizes
• Drying time: A few minutes
• Functions: Safe for use on metal, rubber, nylon, and wood; inhibits rust

During our research into the best nonstick sprays for snow blowers, one of the first things we noticed about CRC’s heavy-duty silicone formula was its rave reviews. It has a loyal following, with many professional handypeople and tradespeople giving it high marks. We couldn’t resist seeing what the fuss was about, so we used it on a snow blower and also sprayed some into stubborn gears on an old fishing reel.

While this CRC spray soaked into the fishing reel gears, we ran the prepared snow blower over a gravel driveway covered with a foot of wet, icy snow. When we hit a section of gravel and dirt we’ve known to be hard on augers and chutes, the CRC formula maintained a nice slick surface and didn’t seem phased by the abrasive snow. As for the fishing rod? It smoothed out its gear performance with plenty of lubrication. Turns out the ample dose of silicone in CRC absolutely does deliver a heavy-duty performance. 

What our tester says: “This is one of the few formulas that meets government regulations regarding the amount of health-harming volatile organic compounds it emits. Since it’s also Food and Drug Administration rated for incidental food contact, we feel good spraying it on squeaky kitchen cabinet hinges and the fishing rod we sometimes use to catch our dinner.”—Zach Lazzari, Product Reviews tester and writer

Best Long-lasting

B’laster Advanced Dry Lube

See It

What We Like

• Works on many materials, including wood and metal
• Prevents the buildup of dirt, debris, and rust
• Has a straw for accurate application

What We Don’t Like

• Can leave a white stain on surfaces

Specs

PrB’laster advanced dry lube spray is designed to lubricate saws, machine parts, and moving elements of machinery without leaving any sticky residue behind. Unlike many of the products we tested, it does not use silicone and also does not contain chlorinated solvents. This means it evaporates quickly and won’t interfere with mechanical functions. 

As a dry lubricant, we noted it set immediately after application, creating a layer of protection that didn’t attract or trap dirt and debris. While it’s not exceptionally slick, it did prevent a coating of snow from forming and causing sticking and clogging. Overall, we appreciate that it performs well on winter tools and also doubles as a lubricant for many other mechanical items.

Best for Metal Chutes

FedPro Free All Deep Penetrating Oil

See It

What We Like

• Low-viscosity option that gets into tiny crevices
• Silicone-free formula does not spread harsh chemicals
• Rust-eating agent completely removes oxygen
• Works on various surfaces, tools, and components

What We Don’t Like

• Not suitable for use on bike chains or belts
• Finish isn’t excessively slick

Specs

• Volume: 11 ounces
• Drying time: Almost immediate
• Functions: Safe for use on metal; inhibits rust

Not all snow blowers are brand new, and many hard-working metal units that have stood the test of time can benefit from a little lubricant. Formulated without silicone, the Free All deep penetrating oil for snow blowers protects against rust and lubricates. It’s also an effective oil for plumbing, automotive, and marine applications.

For augers that have seen a few seasons and chutes that are difficult to turn, this is an excellent product. While not as slick as some other options we tested, it helps coat and lubricate in a way that reduces clogging. For users looking to treat metal components while adding a layer of lubrication to chutes and augers, it’s a great option.

Best For Augers

Stens 752-102 Snow-Jet Snow Blower Spray

See It

What We Like

• Made especially for snow blowers
• Protects against dirt and other debris
• Bottle is on the larger side

What We Don’t Like

• For use on snow blowers only

Specs

• Volume: 11 ounces
• Drying time: Almost immediate
• Functions: Specifically formulated for snow blowers

Augers take a beating when they plow through snow on driveways, patios, and walkways, but the Stens snow blower spray can ensure they are protected and remain effective. This nonstick polymer formula is made with corrosion-resistant agents that prevent the buildup of rust, dirt, and other debris. This makes it a great option for coating and protecting auger blades while still adding a slick layer to the chute and internal passages.

While we liked that this 11-ounce spray is especially made for snow blowers, that specificity does limit its application compared to the rest of the products on our list. Still, It held up very well during testing with the coating lasting through a few uses, and it worked equally as well on a snow shovel and plow blade. We also liked how evenly this option sprayed, ensuring we got a good coating on every surface we applied it to.

Best Precision Application

WD-40 Specialist Silicone

See It

What We Like

• Sprayer reaches tight spaces
• Leaves a clear coating without noticeable residue
• Works at a wide temperature range

What We Don’t Like

• Can gum up if over-applied

Specs

• Volume: 11 ounces
• Drying time: A few minutes
• Functions: Safe for use on nonmetal and metal surfaces; water-resistant

This specialist spray isn’t the WD-40 many people already have in their workshops. Instead, it’s a silicone spray designed to be waterproof without attracting dirt, making it an ideal spray for a snow blower rather than a more simple around-the-house formula. 

During testing, our favorite thing about this product was its unique spray-top design. Its aerosol system has a nozzle that rotates into position, making it easy to hit crevices and hard-to-reach places. The push button also has a big thumbprint that makes it incredibly easy to control. When not in use, the nozzle folds down and out of place.

Adding to its ease of use, this formula stays effective at a wide range of temperatures between -100 to 500 degrees Fahrenheit. If you have a machine needing attention in tight cracks and difficult places, you’ll want to give the WD-40 silicone spray for your snow blower​ a try. 

What our expert says: We asked Gene Caballero, co-founder of GreenPal, an app that connects those needing snow removal and lawn care with a local provider, which nonstick snow blower spray he prefers. He said, “WD-40 Specialist Silicone and Fluid Film have always worked well for me. They not only prevent clogs but also protect your snow blower from corrosion caused by wet, salty conditions.”

How We Tested the Best Nonstick Sprays for Snow Blowers

After researching and comparing product features and reviews for dozens of nonstick snow blower sprays, we narrowed our testing list to eight products. As our property in Montana got hit with one winter storm after another, we had plenty of snow to work through as well as very cold weather, so we got to work lubricating several gas snow blowers, cordless snow blowers, and electric snow blowers with each of our chosen products. 

We applied each snow blower nonstick spray in a dry location, fully covering the chutes, augers, interior boxes, and passageways. A large portion of our work coincided with our tests on snow blowers for gravel driveways, meaning the sprays were all used in particularly rough conditions since the snow contained dirt and hard particles. We also tested them on shovels, plow blades, door locks, and other surfaces needing lubrication to get a comprehensive idea of how long each spray remained effective, their ease of application, and their overall performance. 

What to Consider When Choosing a Nonstick Spray for Snow Blowers 

Before choosing a nonstick spray, take a few minutes to learn what to look for, including drying time, safety concerns, functions, and the spray’s longevity.

Drying Time

The drying time for a spray wax for snow blowers will vary depending on the specific product, the temperature and humidity of the environment, and the moisture content in the snow blower’s chute. Products that dry quickly are generally easier to use since they make applying a second layer when needed faster so you can get to work sooner.

Applying the nonstick snow and ice repellent in a warm, dry environment, like a garage or workshop, is ideal. Warmth helps the spray stick to the metal and dry quickly. Users can apply sprays to damp surfaces in freezing temperatures, but it will take longer for the spray to dry. Until the spray is completely dry, it won’t lubricate properly, nor will it be fully water- or corrosion-resistant.

Safety

While nonstick sprays for snow blowers are helpful in preventing clogs, they often contain chemicals that warrant handling them with care. We recommend you check the product’s label for safe application recommendations and to see if it contains any hazardous materials.

Generally speaking, you’ll want to keep snow blower sprays out of reach of children and pets since they can be toxic if ingested or inhaled. It’s a good idea to use these products in a well-ventilated space and consider wearing eye protection, a respirator, and gloves. Because the liquid spray may be flammable until it dries, store it away from sources of heat or flames. 

Functions

The primary purpose of a nonstick spray for snow blowers is to lubricate the inside of the snow blower chute to keep snow from sticking and clogging the chute. However, many nonstick sprays have additional benefits, such as preventing rust, protecting against ultraviolet (UV) damage, resisting water, or even adding a shine to metal finishes.

• Rust prevention helps protect the metal on the snow blower chute from water, ice, and corrosive salt.
• Water resistance, a common characteristic of nonstick sprays, allows them to repel snow, ice, and water to prevent clogging.
• UV protection ensures that painted surfaces don’t prematurely crack or fade after time in the sun.

Longevity

Longevity refers to the length of time a nonstick spray remains effective after application. Every nonstick spray we tested must be reapplied frequently, though some worked well through several uses. Generally speaking, they all need to be reapplied every few uses at a minimum. 

When working through a really difficult storm, consider reapplying nonstick spray after every use to keep the machine performing optimally. Always apply a fresh coat ahead of storms and continue renewing the coating as needed throughout the season. Even if you go through a couple of cans in the winter, you will still save money removing snow yourself rather than paying the cost of professional snow removal.

FAQs

Learn more about nonstick spray for snow blowers by reading the answers to these frequently asked questions.

Q. Why does my snow blower keep clogging?

Snow blower chutes can clog because you’re trying to push through the snow too fast. They also clog when the heavy snow has a high moisture content and forms compact clumps that stick to the sides of the chute.

Q. Can I use WD-40 on a snow blower?

You can use normal WD-40 to help lubricate the auger and moving parts on a snow blower. Use the silicone version of the product to add a nonstick layer of protection on the snow blower chute and auger. It’s easy to apply, dries quickly, and acts as a water repellent and corrosion inhibitor.

Q. How do I use snow blower spray, and where should I apply it?

Snow blower spray is easy to use: Just shake the can, remove the lid, and spray an even coating inside the chute and to the auger. The nonstick spray lubricant makes the chute and auger slippery, preventing snow from sticking and clogging the blower.

Q. How do I maintain a snow blower?

For a complete set of instructions regarding snow blower maintenance, see our guide on how to maintain a snow blower. While the specific maintenance steps your machine requires will depend on the type of snow blower you have, general steps include checking all fittings and components, changing oil or charging batteries, and lubricating the drive and chassis.
