A Hunker report recommends regular mower-deck cleaning as the main way to manage grass clippings, rather than relying on WD-40 or cooking spray. It also advises mowing when grass is dry, avoiding overly tall grass and keeping the blade sharp; the report is based on the author’s experience, not a comparative product test.
A Hunker report on grass clumping beneath lawn mowers recommends scraping and brushing the deck after each use, rather than relying on WD-40 or cooking spray to prevent buildup. The advice, drawn from the author’s experience operating a landscaping business, also points to dry grass, moderate grass height and a sharp blade as ways to limit clippings sticking to the mower.
The report’s author says the most effective routine was to clean the mower after every use. A putty knife can remove packed clippings from the underside and from areas behind the blade, including around the spindle; a scrub brush can then clear the remaining green film from the deck and blade. The aim is to remove residue before it has time to accumulate, rather than depending on a coating to keep the mower clean.
The author says cooking spray such as PAM, or another lubricant, can make residue easier to remove, but describes the extra step as usually unnecessary when the deck is cleaned regularly. Grass juices and clippings can coat a sprayed surface during mowing, the report says. It does not present a controlled test comparing WD-40, cooking spray and other products, so the advice should be understood as practical experience rather than a measured ranking of products.
For occasional heavier cleaning, the report describes using a garden hose and notes that some modern mowers have deck-cleaning ports designed for hose attachment. Before tipping or cleaning a mower, it says, take care to keep fuel from flowing into engine components or spilling onto the ground. The author recalls running the mower until it used its fuel, or using a hand siphon pump when there was not time to do so.
Less Buildup, Cleaner Cuts
The report says grass packed under a mower can interfere with its performance. The author recommends removing clippings after each use, including material around the blade and spindle, to prevent buildup. That approach also shifts attention from buying or applying a spray to a repeatable maintenance habit.
The report links buildup prevention to mowing conditions as well as cleanup. The author recommends mowing when grass is dry, avoiding letting it grow too tall and keeping the blade sharp so it cuts cleanly rather than shredding grass. These are practical recommendations, not guarantees: lawn conditions and mower designs vary, and the source does not quantify how much each step reduces clumping.

The Report’s Maintenance Advice
The article draws on the author’s account of maintaining two gas rotary mowers while working in a landscaping business during the 1980s and 1990s. The author says mower upkeep included engine tune-ups, oil changes, fuel checks and blade sharpening, alongside removing grass from the underside. The report uses that experience to say cleaning the deck after each use was just as easy as applying lubricant and that spraying was usually unnecessary.
Its recommendations focus on managing clippings and cleaning access. The supplied material does not provide manufacturer instructions for particular mower models or a product-by-product safety assessment. The author cautions readers to prevent fuel from flowing into engine components or spilling when tipping a mower.

Limits of the Product Advice
The supplied report does not state when the article was published, test different sprays under controlled conditions, or quantify how much cleaning, blade sharpness or grass moisture affects clumping. Its conclusions about WD-40 and cooking spray are based on the author’s experience, not a documented comparison. It also does not identify a single cleaning method that applies to every mower model.
The report cautions against letting fuel enter engine parts or spill while a mower is tipped. It does not provide further steps for isolating the engine or securing the blade.

A Repeatable Cleanup Routine
The report recommends clearing clippings after use, removing residue from crevices and using a deck-cleaning port if the mower has one. It also advises mowing when grass is dry, avoiding letting it grow too tall and keeping the blade sharp.
There is no follow-up test or product comparison in the supplied material. The report’s main advice is to treat lubricant as optional and make regular cleaning the routine.

Key Questions
Does the report say WD-40 prevents grass from sticking?
No. The author says WD-40 or cooking spray may make residue easier to remove, but argues that regular deck cleaning is just as effective in the author’s experience. The report does not include controlled product testing.
How should I remove grass clippings under a mower?
The report describes scraping packed grass with a putty knife, including behind the blade and around the spindle, then using a scrub brush to clear the remaining film. Follow the mower’s manual for safe access and cleaning instructions.
What mowing habits can reduce clumping?
The author recommends mowing when the grass is dry, not letting it grow too tall and keeping the blade sharp so it cuts cleanly. The report does not quantify the effect of each step.
Can I tip my mower to clean it?
The report describes tipping a mower but warns that fuel must not flow into engine components or spill. The safe position and preparation vary by model, so check the manufacturer’s manual before tipping or cleaning the mower.
