DuPont Teflon Snow & Ice Repellent, 10 oz Review
Spray the chute and auger housing before each storm and wet snow slides through instead of packing up — the cheapest fix for clogging.
The verdict
A clogged chute is the most annoying thing a snow blower does and the most dangerous thing it tempts you to do (clear it by hand — don't). DuPont's Teflon snow and ice repellent is a dry-film fluoropolymer coating you spray on the chute, impeller housing, and auger housing; wet snow doesn't stick to it, so it keeps moving. It also works on shovels, roof rakes, and the underside of the plow. A can lasts a season and costs less than ten dollars.
Typical price: ~$9 (typical street price — current price shown on Amazon)

Full review
Snow blowers clog for one reason: wet snow sticks to the metal of the chute and housing, each pass adds a layer, and eventually the impeller is spinning in a tunnel of packed slush. You can't change the snow, but you can change the surface. DuPont's Teflon repellent lays down a slick dry film that wet snow doesn't bond to, so the chute keeps its full diameter and the snow keeps flying.
Application is a two-minute job before the storm: wipe the chute and housings clean and dry, spray a light coat, let it flash off. It's a dry film, so it doesn't gather grit the way an oil-based spray would, and it doesn't fling off the first time the auger spins. Reapply every few storms or when you notice snow starting to stick. Owners in the Northeast, where snow routinely falls near freezing, consider it as essential as fuel.
It's cheap, it's easy, and it addresses a safety issue: fewer clogs means fewer temptations to reach into the chute. Spray your shovels and roof rake while you're at it. And if you do clog — engine off, wait, clean-out tool. Always.
Best for: Every snow blower owner in wet-snow country — and anyone tired of slapping slush off a shovel.
