Snowblowers make life much easier when a big storm hits. They save you time and energy while lessening the sore muscles associated with shoveling piles of heavy snow. However, the convenience of these machines is lost if the snow blower auger and chute continually clog. Clogging leads to constant interruption, requiring repeated effort using a specialized tool (or your hands) to remove the snow and ice dams that prevent snow blowers from working properly.
High-quality nonstick sprays can solve gas and electric snow blower woes by lubricating their chutes and augers. To determine which options are best at minimizing and eliminating sticking and clogging, we tested several different nonstick sprays for snow blowers. We used each during a heavy Montana snowfall that began with a nice powder and evolved into a wet mess. In addition to testing them on a snow blower, we also applied the sprays with several electric snow shovels to create a more comprehensive test. Each product that made our final list performed well, and a few stood out from the rest by making an especially big difference in how snow projected through the chute.

How We Chose the Best Nonstick Sprays for Snow Blowers
Initially, our team researched and compared product features and reviews for dozens of nonstick snow blower sprays across the market. We narrowed the list to eight different products and performed hands-on tests using each. The resulting ratings and awards are based on those tests.
Our testing environment had very cold weather and plenty of snow to work through. We lubricated each snow blower in a dry location, covering the chute, auger, interior box, and passageways. We concentrated on applying thorough and focused full coverage rather than conserving product to ensure each option was given a fair chance.
A large portion of the testing coincided with our tests on snow blowers for gravel driveways. Working over gravel creates a more abrasive texture since the snow contains dirt and hard particles, meaning the sprays were all used in particularly rough conditions.
We determined the final ratings based on how long each spray remained effective, their ease of application, and their overall performance. We predominantly tested these sprays on snow blowers, but their usefulness on shovels, plow blades, door locks, and other surfaces needing lubrication is worth mentioning.

The DuPont Teflon snow and ice repellent spray is made with the specific purpose of making surfaces nonstick. It’s designed to build a barrier between the surface it’s applied to and contact with snow and ice. The Teflon fluoropolymer and silicone combination adheres well to smooth surfaces, and it repels moisture in liquid and frozen forms.
As with any nonstick spray, adherence is best when applied in a dry environment. Thus, we began by wiping down the chute and auger surfaces well. The Teflon snow and ice spray was easy to apply, and it also dried quickly in a fairly cool climate. To test for readiness, we simply pressed our finger against the sprayed surface to ensure it was fully dry. After about 10 minutes, it was ready for use.
When using our sprayed snow blower, we were careful to hit a combination of powder and a few slushy patches that would usually be problematic to clear. The powder flew through the snow blower chute without issue, and the wet snow did as well. We didn’t experience any clogging, and the coating lasted through a long snow-clearing session without reapplication.

Liquid Wrench M914 is an aerosol spray with a heavy silicone base, and it takes the runner-up position because it sticks well to slick surfaces and provides optimal nonstick performance. Silicone is a natural water repellent, and it works very well for a number of purposes. From fixing squeaky hinges to adding a waterproof barrier to surfaces, it’s a handy material to keep on hand.
For snow blowing specifically, the M914 silicone spray from Liquid Wrench was a great lubricant. Its dry time was similar to our top choice, and it leaves a nice clear finish with no residue. After running through a walkway and driveway with wet snow, we didn’t have any snow blower clogging, and the chute remained clean.
This is a great multifunctional product for a snow blower or snow plow during winter and is useful for keeping them lubricated as an off-season maintenance treatment. After using the product while snow blowing, we even added it to some squeaky oarlocks on our boat.

Another DuPont favorite is this dry film lubricant aerosol option. It’s formulated using nonstick ceramic technology that enables it to adhere quite well on metal surfaces. This makes it an especially good option for use on snow blowers with steel augers and metal chutes, though it does also work on plastic.
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 under $10 for a 10-ounce can, it’s a great value.

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 is 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.
CRC has an ample dose of silicone to deliver its heavy-duty performance. It’s also one of the few formulas that’s volatile organic compound (VOC)–compliant, meaning it meets government regulations regarding the amount of health-harming VOCs it emits. It’s also Food and Drug Administration rated for lubricants with incidental food contact, which expands its potential applications to kitchens and other environments.

Augers take a beating when they plow through driveways, patios, and walkways. To ensure they are protected and effective, try the Stens snow blower spray. This nonstick polymer formula is made with corrosion-resistant agents that prevent the buildup of rust, dirt, and other debris.
We liked that the 11-ounce spray is specially made specifically for snow blowers. It held up very well, and the coating seemed to last through a few uses. This makes it a great option for coating and protecting auger blades while still adding a slick layer to the chute and internal passages. It would work equally well on a snow shovel or plow blade. It also sprays evenly, making it easy to coat surfaces.

This specialist spray isn’t the WD-40 many people already have around the house. It’s a silicone spray designed to be waterproof without attracting dirt.
Our favorite thing about this product during testing 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.

What to Consider When Choosing a Nonstick Spray for Snow Blowers
Before choosing a nonstick spray to help maintain a snow blower, take a few minutes to learn what to look for, including drying time, safety concerns, functions, and the spray’s longevity.
Drying Time
A nonstick spray’s drying time varies depending on the specific product, the ambient temperature, humidity, and the moisture content of the snow blower chute. A quick drying time allows for multiple applications in a short amount of time, making applying a second layer when needed a faster process.
The only caveat for snow blowers, whether gas, corded electric, or cordless, is that they operate in wet environments. Users can apply a spray to a wet snow blower, but having a clean, dry surface is best. It might be best to dry the snow blower before application to ensure it adheres properly.
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 can contain hazardous chemicals that warrant handling with care. Check the product’s label for the manufacturer’s recommendations to determine the proper way to apply and use the spray and learn if contains any hazardous materials.
Some general rules apply when using nonstick snow blower sprays. Keep them out of reach of children and pets because they can be toxic if ingested or inhaled. Because the liquid spray may be flammable until it dries, store it away from sources of heat or flame. Use nonstick spray in a well-ventilated space and consider wearing eye protection, a respirator, and gloves to mitigate contact with its hazardous ingredients.
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 ultraviolet (UV) damage, resisting water, and even adding a shine or gloss to the metal finish.
- Rust prevention helps protect the metal on the snow blower chute from water, ice, and corrosive road 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 long periods in the sun.
Longevity
Longevity refers to the length of time a nonstick spray remains effective after it’s applied. Every nonstick spray we tested must be reapplied frequently. Realistically, users might see the benefits through several uses. Some last a little longer than others, but they all will need to be reapplied every few uses at a minimum.
When working through a really difficult storm, consider reapplying spray after every use to keep the machine performing at its highest level. Always apply a fresh coat ahead of storms and continue renewing the coating as needed throughout the winter seasons.
FAQs
Learn more about nonstick spray for snow blowers and how to maintain a snow blower 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 on the interior of the chute. The nonstick spray lubricant makes the chute’s sides slippery, preventing snow from sticking and clogging the blower.
