A Hunker report says the most dependable way to limit grass buildup is to clean the mower deck and blade after each use. It also recommends mowing before grass gets too tall, waiting until it is dry, and keeping the blade sharp; lubricants such as WD-40 may make residue easier to remove but are not presented as a substitute for cleaning.
A Hunker report says regular cleaning—not spraying a mower deck with WD-40—is the main way to limit grass clippings building up beneath a lawn mower. The report’s author, drawing on experience maintaining gas rotary mowers, also advises mowing dry grass, avoiding overgrown lawns and keeping the blade sharp to reduce buildup and help the mower cut cleanly.
The author says cleaning the deck and blade after each use was the most effective method he used while operating a landscaping company with his wife in the 1980s and 1990s. He describes scraping off lodged grass with a putty knife, including behind the blade near the spindle, then using a scrub brush to remove the remaining green film. He says he sometimes rinsed the mower after larger jobs and notes that some modern mowers have hose-cleaning ports.
The report does not say that lubricants never help. The author says cooking spray such as PAM, or a lubricant such as WD-40, can make the coating easier to remove. But grass juices and cuttings can cover the sprayed surface during mowing, leaving residue that still needs to be cleaned. In his account, applying spray was usually an optional step rather than a replacement for routine deck maintenance.
The three additional practices the report recommends are to avoid letting grass grow too high, mow only when the grass is dry, and keep the blade sharp. The author says a sharp blade cuts grass cleanly rather than shredding it. The report also describes removing grass by turning a mower on its side or onto its back, while warning that fuel must be kept from flowing into parts of the motor where it should not go or spilling onto the ground.
Cleaner Decks, Better Cutting Conditions
Grass packed around the deck and blade can interfere with a mower’s operation, according to the report, which links buildup with the risk of affecting performance. Routine removal also gives the operator a chance to clear clippings from hard-to-reach areas before they accumulate. For homeowners, the practical point is that cleaning after use is a repeatable maintenance step, while a lubricant alone does not prevent clippings from collecting during the next mowing session.
The advice also connects mower upkeep with how and when a lawn is cut. Mowing dry grass and keeping the lawn from becoming too tall are presented as ways to reduce the conditions associated with buildup. A sharp blade, meanwhile, is intended to cut rather than shred grass. These are recommendations from the report’s author, not results from a cited controlled test, so the source does not quantify how much each measure reduces clumping or improves performance.

The report is based in part on the author’s experience maintaining two gas rotary mowers for landscaping jobs during the 1980s and 1990s. His routine included standard engine care—such as changing oil, checking fuel and maintaining the blade—as well as clearing grass from the deck and blade. He describes a simple approach rather than a specialized product treatment: remove the clippings after mowing and use a brush or scraper where needed.
For fuel management during cleaning, the author says he generally ran the mower until it ran out of gas. If that was not practical, he used a hand siphon pump to empty the tank and replaced the fuel after cleaning. The source advises care when tilting or turning over a mower to prevent fuel from reaching unintended engine areas or spilling. Owners should also follow the safety and maintenance instructions for their specific mower; the report does not provide model-specific procedures.
“The technique I found most effective was simply to clean off the grass cuttings after every use.”
— Hunker report author
Limits of the Report’s Advice
The supplied report does not give a publication date, test data, or a measured comparison between cleaning alone and using WD-40 or cooking spray. It also does not quantify how much mowing dry grass, cutting more often, or sharpening a blade changes the amount of clumping. The recommendations are presented as the author’s experience and advice, rather than as findings from a controlled comparison.
Cleaning methods can vary by mower design, and the source does not set out instructions for every model or explain when a particular mower can safely be tipped. The appropriate direction for tilting, fuel handling and use of a cleaning port should be checked in the machine’s manual. The report also does not establish whether a specific lubricant is suitable for every mower component.
Check Your Mower Before Cleaning
For a mower owner following the report’s advice, the next step is to check the manufacturer’s manual for safe cleaning and fuel-handling instructions, then clear grass from the deck and blade after use. The report suggests using a scraper and brush for dried or lodged clippings and using a hose port if the mower has one and its instructions permit it. Before mowing again, check whether the grass is dry, whether it has become overgrown, and whether the blade needs attention. The source gives no schedule for blade sharpening or further product testing.
Key Questions
Does the report say WD-40 is useless for mower clumping?
No. The author says WD-40 or cooking spray may make the grass coating easier to remove. The report’s point is that sprays do not replace cleaning, because clippings and grass juices can cover the treated surface during mowing.
What cleaning method does the author recommend?
The author describes scraping lodged grass from the deck and areas behind the blade with a putty knife, then brushing away the remaining film. He says he cleaned the mower after each use.
What mowing practices may reduce grass buildup?
The report recommends mowing when the grass is dry, avoiding letting it grow too tall, and keeping the mower blade sharp. These are the author’s recommendations; the source does not quantify their effects.
Can I turn my mower over to clean it?
The report describes tilting a mower or turning it onto its back, but warns about fuel entering unintended engine areas or spilling. Check the manufacturer’s manual for the correct cleaning position and safety steps for your model.
