Snow blowers make light work of heavy snow, saving backs and shoulders from the strains of shoveling. However, snow with a high moisture content can form densely packed clumps that stick to the insides of the snow blower chute. When more snow gets pulled into the snow blower, it clings to the stuck clump, creating a clog instead of being pushed through the chute.
Nonstick spray works as a lubricant to prevent snow from sticking to the metal chute. The best nonstick sprays for snow blowers also create a water-resistant barrier and may even prevent rust, resist corrosion and UV rays, and leave a sleek shine. Keep reading to learn about other important characteristics to look for when shopping for nonstick spray, and consider some of the top picks in this list, so you don’t get stuck shivering in your boots as you try to clear a clog.

What to Consider When Choosing the Best 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 in a nonstick spray, including drying time, safety concerns, functions, and the spray’s longevity.
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, and users can apply a second layer when it’s needed.
For the best results, apply the nonstick spray in a warm, dry environment, like a garage or workshop. Warmth helps the spray stick to the metal and dry quickly. Most nonstick sprays can adhere to wet 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.
While nonstick sprays for snow blowers are helpful in preventing clogs, they can contain hazardous chemicals that should be handled 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 whether any potential hazards exist in using it.
Some general rules apply when using these 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.
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 and/or UV rays, 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 refers to the length of time a nonstick spray remains effective after it’s applied. One-time use nonstick sprays must be reapplied before every use, which can take precious minutes when the driveway must be cleared before leaving for work. Sprays that are effective for longer periods allow the snow blower to be used several times before the user must lubricate the chute again.
While it’s a good idea to reapply nonstick spray before every use, many products are effective for up to 4 weeks. To achieve optimal longevity and lubrication, users typically must apply more than one coat of these sprays.

Q. Why does my snow blower keep clogging?
Snow blower chutes can clog because the user is trying to push through the snow too fast. They also clog when the heavy snow has a high moisture content and form compact clumps that stick to the sides of the chute.
Q. Can I use WD-40 on a snow blower?
You can use WD-40 to help lubricate the snow blower chute. It’s easy to apply, dries quickly, and acts as both 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 lubricates the chute’s sides, preventing snow from sticking and clogging the blower.
