Applying the spray to your mower blades is fairly easy, as long as you put in a bit of prep work first. Make sure you safely clean your lawn mower by removing the spark plug or battery first. In a well-ventilated area, spray the Mo-Deck Non-stick Mower Blade Spray in a thin layer all over the blades and the deck of the mower, being careful not to inhale the mist. However, quite a few people agreed that removing any stuck grass was far easier when hosing down the lawn mower after use. The price is also a little steep at just over $20 per can, but if you're tired of gunky mower blades, it may be worth testing for yourself.
