If you’ve shoveled much snow, you might have noticed that after a while, snow tends to stick to the blade. This can increase the effort when you shovel snow.
You can fix this by spraying the shovel with vegetable oil cooking spray. The snow slides right off. This even works on garden shovels and hoes. Vegetable oil is easily biodegradable so it doesn’t harm the soil. Vegetable oil spray also works well on lawnmower blades.
