Grilling is a popular cooking method during the warmer months. It allows you to cook food over an open flame and impart delicious charred flavors. However, the high heat also leads to the buildup of stuck-on food and grime on your grill grates. This debris needs regular cleaning to prevent flavor transfer and potential bacterial growth. Using a stiff metal grill brush seems like an easy way to scrub the grates clean. But is it the best option? There are some pros and cons to consider before grabbing a metal grill brush.

The benefits of a metal grill brush
Metal grill brushes have some advantages that explain their popularity:
- They are inexpensive and readily available. You can find metal grill brushes at any grocery store or hardware shop for just a few dollars.
- The metal bristles are very stiff and sturdy. This allows them to scrape off chunks of stubborn baked-on food.
- They quickly remove surface debris, char, and grease from grill grates.
- Many people already own and are familiar with metal grill brushes.
With a simple scrubbing motion, a metal brush can lift off all the stuck-on grime to reveal clean grill grates. The bristles get into the small cracks and crevices between the grate bars. For a basic surface-level cleaning, metal grill brushes seem like the ideal tool.
Potential risks of metal grill brushes
However, some drawbacks are associated with metal-bristled grill brushes:
- The bristles can break off and stick to the grill grate if the brush is used too vigorously. These bristles can be difficult to remove.
- Loose bristles can also fall off the grill into your food without you noticing.
- If accidentally ingested, the thin metal bristles can cause serious internal damage. They can get lodged in the throat, gums, intestines, etc.
- The bristles scratch and damage the protective coating on porcelain grill grates over time, leading to rust and corrosion.
- Bacteria and mold can grow in the crevices between the bristles if the brush is stored while still wet.
- The bristles wear out and fall out over time with repeated use. This leaves behind metal stubs that are even more dangerous.
These risks have led many health and safety experts to warn against using metal-bristled grill brushes altogether. There have been multiple reported cases of people requiring surgery to remove ingested bristles.
Safer alternatives for grill cleaning
Luckily, there are plenty of ways to clean your grill that don’t involve metal bristles. Here are some of the best metal brush alternatives:
Wooden scrapers
Scrapers made from wood or bamboo are naturally tough enough to remove debris without being abrasive. Hold the scraper at an angle and apply firm pressure to lift off stuck-on bits. Scrapers easily get in between grate bars. Just remember to scrape in the direction of the bars – not perpendicular to them – to avoid splinters.
Plastic bristle brushes
For a brushing action, look for grill brushes made with plastic (nylon, polypropylene, etc.) rather than metal. The stiffer plastic bristles can dislodge grime without the risk of broken bristles. Make sure to check that the bristles are securely fastened to the brush head before each use.
Onion
Believe it or not, a raw onion can work wonders for cleaning your grill! Cut an onion in half and rub the cut side all over the grates while they are still warm (not hot). The moisture lifts residue while the onion acids break it down. Rinse off with water when finished.
Baking soda
For a DIY grill cleaning solution, mix baking soda with just enough water to form a loose paste. Apply the baking soda paste to grates using a cloth or soft brush. Let sit for 15-20 minutes before rinsing clean.
Citrus solution
Another safe home remedy is mixing equal parts juice from lemons/limes with vinegar or dish soap. Pour or brush onto grates, let sit briefly, then scrub and rinse.
Salt
If you notice food sticking during the cooking process, immediately sprinkle some salt. The coarse grains help scrape off the food bits as you continue grilling. The salt grains then just fall between the grates into the ashes when you are done.
Chainmail scrubber
These unique scrubbers are made from interlocking stainless steel rings, like old-fashioned chainmail armor. The abrasive surface easily scours away every last bit of residue without damaging the grill. Chainmail scrubbers conform nicely to grate curves and won’t harbor bacteria.
Steel grill stone
These solid rectangular bricks made of textured stone provide heavy-duty cleaning. Holding the grill stone with long tongs, scrape it back and forth across the grates under firm downward pressure. The durable stone wears away any stuck-on gunk. Rinse after each use and allow it to fully dry to prevent mold growth.
Sandpaper pad
In a pinch, you can tear off a sheet of regular sandpaper and fold it over a few times to create a cleaning pad. Hold it with tongs and rub in direction of the grate bars. The abrasive paper scrapes off even the most stubborn burned bits. Just don’t use this too often, as the sanding action will gradually damage the grates.
Proper grill cleaning tips
To make grill cleaning easier and help prevent damage, keep these tips in mind:
- Use grilling tools with wood handles instead of metal, as they are less likely to nick or scrape the grates.
- Give grates a quick brushing with a stiff plastic brush during grilling while the grill is still hot. It is much easier to remove any food debris before it gets burned on and sticks tightly.
- Always make sure grates have cooled completely before doing a thorough post-cooking cleaning.
- After cooking fatty meats or oily foods, heat the empty grill on high for 5-10 minutes to burn everything off.
- For discoloration or rust spots, let grates soak in a solution of vinegar, salt, and water for 30 minutes before scrubbing.
- Clean your grill brush regularly by swishing bristles in soap and water. Disinfect in a dilute bleach solution.
- Replace grill brush bristles at the first sign of bending, breaking, or shedding.
- Store grill brush hanging up or with the bristle-side up to allow air circulation and drying.
Conclusion
While metal grill brushes may seem like the quickest and most convenient option, they come with risks. Plastic brushes, scrapers, and other natural cleaning methods are safer and still effective. With the right non-abrasive tools and some post-cooking care, you can keep your grill grates clean without damaging them.
Focus your scrubbing efforts on removing stuck-on food remnants rather than trying to make the grates look brand new. A little surface wear gives grates character and actually makes them perform better over time. With regular gentle cleaning, you will still be able to keep your grill in great shape for years of barbecuing.
