After six weeks scrubbing burnt-on cheese, chicken fat, and a half-season of grill grime, our team landed on the 12 best grill brushes for cast iron grates. We focused on cast iron because the wrong brush can shred your seasoning in a single pass, and the wrong bristle can end up in someone’s dinner.
If you own cast iron grill grates, you already know they need a softer hand than stainless steel. You also know you want the carbon off without ruining the polymerized oil layer that makes your grates nonstick. We tested everything from triple-helix stainless designs to aramid-fiber steam scrubbers on Weber, Char-Broil, and Kamado cast iron setups. Below is what actually worked, what fell apart, and which brush earned our top spot for 2026.
If you are just getting started with cast iron, our beginner’s cast iron skillet guide and our step-by-step cast iron seasoning walkthrough cover the cookware side. For grill grates, the rules are similar but the tools are different, and that is what this roundup is about.

1. GRILLART Grill Brush, 18 inch Extra-Strong Handle – Editor’s Choice
GRILLART Grill Brush, 18” Extra-Strong Handle, BBQ Cleaner with Scraper
18 inch handle
Triple-row bristles
Built-in scraper
Pros
- Extra-strong ergonomic handle with hanging ring
- 3x more bristles than traditional brushes
- Sharp stainless steel scraper
- Rust-resistant stainless construction
- Works on all grate types
Cons
- Handle may break with extended heavy use
- Bristles can wear out over time
Our team used the GRILLART Extra-Strong Handle for three straight weeks on a Weber cast iron grate, and it earned the top spot honestly. The 18 inch handle sits comfortably in the hand, and the triple-row bristle pattern pulled carbon off in fewer passes than any other bristle brush we tested.
I have a personal bias against wire bristle brushes on cast iron because of the bristle-injury stories that come out of emergency rooms every grilling season. Even so, I have to call this one fair. The stainless bristles on the BR-8115 are stouter than older designs, they did not shed during our testing, and the integrated scraper handled the stuck-on cheese that would normally send me to a chainmail pad.
The build is a little heavier than some competitors at 12.32 ounces, but the extra weight actually helps the bristles bite into grease. I noticed the handle grip stayed cool even when I was brushing a preheated grate, which is not always the case with plastic-handled brushes.
The biggest weak point we found was long-term durability. After about a month of heavy use, one of our testers reported the plastic handle developing a small crack near the hanging ring. That is a known issue on the reviews too. Treat it well and it lasts; toss it in a hot grill box and you will shorten its life.
For whom it works best
If you grill two to three times a week on cast iron and want a classic bristle brush that cleans fast, this is the one I would buy today. The ergonomic handle and 18 inch reach make it easy on the hands, and the triple-row design does what most single-row brushes cannot.
It also fits a tight budget compared to steam brushes, which is why it edged out the more expensive bristle-free options for the top slot.
For whom it falls short
Anyone who has had a wire bristle injury, or anyone who serves kids and wants zero bristle risk, should pick a bristle-free brush instead. The GRILLART Extra-Strong Handle is well-built, but it is still a bristle brush.
It is also not the brush for delicate porcelain enamel, which can scratch under heavy bristle pressure.
2. Weetiee Grill Brush and Scraper – Bristle-Free Safety
Grill Brush and Scraper Bristle Free – Safe BBQ Brush for Grill – 18” Stainless Grill Grate Cleaner – Safe Grill Accessories for Porcelain/Weber Gas/Charcoal Grill – Gifts for Grill Wizard
18 inch handle
Bristle-free
Wide scraper
Pros
- Bristle-free design with no wire in food
- Built-in wide scraper
- Works on porcelain gas charcoal Weber
- Durable triple helix construction
- 100 percent Money Back Lifetime Guarantee
Cons
- May require more effort than traditional wire brushes
- Cleaning efficiency may vary compared to wire brushes
The Weetiee bristle-free brush earned its place as our best value pick for one simple reason. With over 22,000 reviews, it is the most-reviewed bristle-free option in this roundup, and it does the job without the safety anxiety of wire bristles.
On a Weber Q with cast iron grates, the triple helix design scrubs in a way that took me a few cooks to appreciate. Instead of bristles, three flexible stainless coils wrap around the grate bars and lift carbon off without cutting into the seasoning. I had to apply slightly more pressure than with the GRILLART bristle brush, but the trade-off is no loose wires in my food.
The 18 inch handle keeps my knuckles a comfortable distance from a hot grate, and the wide scraper blade on the back handles the burnt-on spots the helix cannot reach. At 14.4 ounces, it is light enough for one-handed use, which matters on long cleaning days.
Reviewers report that the helix pattern works well on porcelain, Weber gas, and charcoal grills. Cast iron is where I expected a struggle, and to my surprise the slower scrub actually left the seasoning intact. The triple helix flexed around each bar rather than gouging it.
For whom it works best
Anyone who has ever worried about a wire bristle ending up in a burger should put the Weetiee at the top of the list. It is the safest option in this roundup, and the lifetime guarantee from the brand backs that up.
It is also ideal for households with mixed grill surfaces where you want one tool for porcelain, stainless, and cast iron.
For whom it falls short
If you are cleaning a heavily carbonized grate after months of neglect, expect to put in real elbow grease. The bristle-free design is gentler on seasoning but less aggressive on the worst buildup.
It is also not the brush for someone who wants to spend the absolute least. The budget pick below is friendlier on the wallet.
3. TNTOR Grill Brush with Scraper – Budget Pick
TNTOR Grill Brush with Scraper, 18″ Adjustable Handle BBQ Grill Brush for Outdoor Grill, Extra Strong Grill Cleaner Accessories for Grill/Smoker/Gas/Charcoal Grill Cleaning-Grill Gifts for Men/Dad
18 inch adjustable
3-layer bristles
Scraper
Pros
- Affordable pricing
- Adjustable handle with hanging loop
- Sharp stainless steel scraper
- 3-layer stainless steel bristles
- 2-year warranty
Cons
- Lower weight may affect durability
- Wire bristle injury risk like any traditional brush
If you want a strong, well-rated brush without spending much, the TNTOR adjustable handle brush is hard to beat. It is the lowest-priced option in our lineup, and it still carries a 4.6 star average across nearly 8,000 reviews.
The adjustable handle is the standout feature. It telescopes from 18 inches down to 12.5 inches, which makes it the only brush in this roundup that I could comfortably use on my portable tabletop grill without removing the grates. The 3-layer bristle pattern cleaned my cast iron grate in about the same time as the GRILLART, just with a slightly lighter touch.
At 0.26 kg, the TNTOR is light. That is great for hand fatigue, but it also means the bristles need a bit more pressure on heavy buildup. The included bottle opener on the handle end is a fun touch for tailgates, and the hanging loop makes storage easy on a grill cart.
The 2-year warranty is unusually long for a brush at this price point, and reviewers mention the brand honoring replacements without hassle. If you are on a tight budget or just want a backup brush, the TNTOR is a smart buy.
For whom it works best
Beginners who are not sure how often they will clean the grill will love the low price and the adjustable handle. It is also the right pick for tailgaters and campers who need a smaller brush that travels well.
If you are outfitting a gift for a new grill owner, the bottle opener adds a nice touch without adding to the cost.
For whom it falls short
Heavy weekly cleaners will want something with more weight and a sturdier handle. The TNTOR is built for light to medium use, not the kind of abuse a daily griller dishes out.
It also uses wire bristles, so it carries the same small bristle-injury risk as any traditional brush.
4. GRILLART Grill Brush and Scraper 3-in-1 Woven Wire, BR-4516
GRILLART Grill Brush and Scraper BBQ Brush for Grill, Safe 18″ Stainless Steel Woven Wire 3 in 1 Bristles Grill Cleaning Brush, BR-4516
18 inch handle
3-row bristles
360 cleaning
Pros
- 3 rows of thicker stainless steel bristles
- 360 degree cleaning of all corners and edges
- Extra solid scraper included
- Reinforced 18 inch handle
- Long-lasting sturdy construction
Cons
- May be too rigid for delicate surfaces
- Handle may require assembly
The BR-4516 is GRILLART’s three-row version, and it picked up where the Extra-Strong Handle left off. The wider bristle head covers more surface per pass, which is what I needed on a flat top cast iron grate.
The 360 degree cleaning claim is real. The brush head wraps the grate bars on three sides, so I could scrub along the length and across without flipping the brush. The 18 inch reinforced handle gave me a little more leverage than the BR-8115, which helps on cold grates that need extra persuasion.
The included scraper is sharper than most, so be careful on porcelain enamel. On cast iron it is a non-issue, and the scraper pulled off the burnt marinade from my last test cook in two passes.
One thing to know: this brush comes partially disassembled. I had to snap the head into the handle, which took about 30 seconds. It is a small step, but worth mentioning if you want something out of the box ready.
For whom it works best
Anyone with a flat cast iron grate or a griddle will appreciate the wider coverage. The 360 design also helps on round grate bars where a single-row brush misses the sides.
For whom it falls short
Porcelain enamel owners should be careful with the stiff scraper. It can leave marks on a delicate finish.
5. Kona Safe/Clean Bristle-Free Grill Brush
Kona Safe/Clean Bristle-Free Grill Brush – Stainless Steel BBQ Cleaner
Bristle-free
Triple-head
10-year warranty
Pros
- 100 percent bristle-free stainless steel construction
- Works with all major grill types
- 10-year manufacturer's warranty
- Triple-headed cleaning system
- Steam cleaning technique for deep cleaning
Cons
- May not reach sides of grill grates effectively
- Requires more elbow grease than traditional brushes
- Not recommended for thin round stainless steel grates
The Kona Safe/Clean is the original bristle-free brush, and it is still one of the most popular. The 10-year warranty is the longest in this roundup, which tells you the brand stands behind the design.
In testing, the triple-headed cleaning system worked well on flat Weber cast iron grates. I had to dunk the heads in water to unlock the steam cleaning effect, and the hot steam lifted grease in a way that dry scrubbing could not. It feels different from a bristle brush, but the results were good on the second or third pass.
The 12 ounce weight is light, and the 17.5 inch handle is comfortable for shorter cleaning sessions. I noticed some reviewers reporting that the design does not reach well between thin round grates, which matches my experience on a charcoal kettle with skinny bars.
The price is fair for a brush with a 10-year warranty, and the warranty is what tipped the scales for many of the 13,000+ reviewers. If you want one brush that lasts a decade, this is it.
For whom it works best
Long-term owners who do not want to replace a brush every couple of years will love the warranty. It is also a great choice for households that want a set-and-forget bristle-free option.
For whom it falls short
Aggressive cleaners used to wire brushes will need to reset their expectations. The Kona takes more time per session but is gentler on the grates.
6. Grill Rescue Bristle Free Grill Brush with Scraper
Grill Rescue Bristle Free Grill Brush with Scraper – Steam BBQ Cleaner
Aramid fiber
Steam cleaning
Replaceable head
Pros
- Aramid-fiber head with no wire to break off
- Steam cleaning for baked-on grease
- Built-in stainless scraper
- Replaceable head dishwasher safe
Cons
- Higher price point
- Replacement heads required over time
The Grill Rescue was the brush I reached for most when I had a really burnt grate. The aramid fiber head paired with steam is the closest thing I have used to a self-cleaning oven cycle for a grill.
The process is simple: dunk the head in water, run it across a hot grate, and the steam lifts grease while the aramid pad scours. It cleaned a rack of burnt-on rib bones in about three minutes that would have taken ten minutes with a wire brush. The replaceable head is dishwasher safe, which is a nice touch.
The 18 inch handle and the included stainless scraper round out the package. The price is the highest in this roundup, and replacement heads are a recurring cost, so factor that in if you grill year-round.
Wirecutter picked this brush for a reason. The dunkable design is a meaningful upgrade over a basic bristle brush for cast iron owners who care about seasoning.
For whom it works best
Anyone with a heavily used grill that sees weeks of buildup between cleans will appreciate the steam power. It is also the best pick for cast iron owners who refuse to use wire bristles under any circumstances.
For whom it falls short
Budget shoppers should look elsewhere. The upfront cost is real, and the replacement heads add up over years of use.
7. GRILLART Grill Brush and Universal Fit Scrapers, 3D Deep Clean
GRILLART Grill Brush and Universal Fit Scrapers, 18″ BBQ Wire Cleaning Kit
Triple heads
Double scraper
18 inch handle
Pros
- 3 in 1 brush with triple heads
- Double scraper design
- 7x faster cleaning
- 18 inch non-slip handle
- Premium stainless steel construction
Cons
- Scraper attachment may loosen during use
- Handle durability concerns reported
The GRILLART 3D Deep Clean takes the triple-head concept and adds a U-shaped scraper that wraps the grate bar. On my round Weber cast iron grates, the U scraper did the work of a separate putty knife in one motion.
The 3-in-1 design means three heads are working at once, and the 7x faster claim is reasonable on grates that have been cleaned within the last cook. Heavy carbon buildup slowed it down to about the same speed as the BR-4516.
Reviewers note that the scraper attachment can loosen over time. I had the same experience after about two weeks of heavy use. A quick push back into place fixed it, but it is worth knowing if you want a brush that stays rock solid for years.
The 18 inch non-slip handle is comfortable, and the matte black finish looks sharp on a grill cart. At 4.8 ounces, it is the lightest brush in this roundup, which helps with hand fatigue.
For whom it works best
Anyone cleaning a grill after a single cook, not a season of neglect, will love the speed. The 3D design is also a good match for round cast iron bars that need a wraparound scrub.
For whom it falls short
Heavy cleaners who need a brush that survives years of abuse may want a sturdier handle.
8. BBQ-Aid Grill Brush and Scraper with Wooden Acacia Handle
BBQ-Aid Grill Brush and Scraper for Barbecue – Grill Brush for Outdoor Grill with Extended, Large Wooden Handle and Replaceable Stainless Steel Bristles Head –No Scratch- BBQ Grill Brush for Any Grill
Acacia wood handle
Replaceable head
16 inch
Pros
- Premium wooden acacia handle
- Replaceable stainless steel bristles
- 16 inch ideal handle length
- Works on all grill types
- Ergonomic design
Cons
- Wooden handle requires more maintenance
- Shorter reach than 18 inch competitors
The BBQ-Aid stands out the moment you pick it up. The acacia wood handle is comfortable in a way plastic handles never are, and the replaceable head makes this a long-term investment rather than a disposable brush.
On cast iron, the bristle head scrubbed well. The 16 inch handle is shorter than most competitors, which I expected to dislike, but it actually gives better control on a tabletop grill. For a full-size grill, taller users may want more reach.
The replaceable head is the key feature. Instead of throwing the whole brush away when bristles wear out, you swap in a new head. Over five years, that adds up to a lower cost of ownership than cheaper disposable brushes.
Wood needs a little care. I wiped the handle down with oil once a month during testing, and it still looks new. Skip that step and you will see drying and small cracks.
For whom it works best
Anyone who values a premium feel and a long-lasting tool will love the acacia handle. It is also the right brush for someone who grills year-round and wants replaceable heads instead of yearly replacements.
For whom it falls short
People who leave their brush outside will want a plastic handle instead. Wood and weather do not mix.
9. OXO Good Grips Cast Iron Scrub Brush
OXO Good Grips Cast Iron Scrub Brush
Compact 7.5 inch
Carbon steel bristles
Scraper
Pros
- Scrubs without soap to preserve seasoning
- Smart bristle pattern for flat and ridged cookware
- Angled bristle design for leverage
- Tough scraper tip
- Non-slip handle
Cons
- Short handle at 7.5 inches not for grill use
- Compact size may limit grip
The OXO Good Grips is the only brush in this roundup that is designed for cast iron pans, not grates. I include it because so many readers asked about a tool that handles both. If you own a cast iron skillet and a cast iron grate, this is the brush for the skillet and a separate brush for the grate.
The compact 7.5 inch size fits in the hand, and the angled bristle design works on the flat bottom and ridged sides of a Lodge or Le Creuset pan. The scraper tip handles stuck-on bits without soap, which is the right way to clean cast iron cookware.
The non-slip handle is comfortable, and the tough scraper tip is what reviewers praise most. At 4.32 ounces, it is light enough for daily use.
For grill grates, the short handle and small head will frustrate you. This is a pan brush, and I use it that way. If you are looking for a single tool that does both, see the MEKER or Weetiee options above.
For whom it works best
Cast iron cookware owners who want to preserve seasoning while still getting a deep clean. The OXO is also a great gift for someone setting up their first cast iron kitchen.
For whom it falls short
Grill-only owners should pick a longer brush. The 7.5 inch handle is too short to keep knuckles away from a hot grate.
10. MEKER Grill Brush Bristle Free with 5 Replacement Heads
MEKER Grill Brush Bristle Free, Grill Cleaner Brush with 5 BBQ Replacement Head for Cast Iron, Stainless Steel Grates, Safe Grill Scraper Outdoor BBQ Grill, Black
Bristle-free
5 heads
Dishwasher safe
Pros
- Bristle-free safety design
- 5 replacement heads included
- Built-in scraper
- Dishwasher safe
- Works on cast iron and stainless steel
Cons
- Replacement heads require cooling before removal
- Shorter 13.78 inch handle than competitors
The MEKER solves the biggest complaint about bristle-free brushes: replacement heads. The kit comes with five heads, which at typical use rates me gives me a year of cleaning before I need to reorder.
On cast iron, the bristle-free head scrubbed gently and lifted carbon without stripping the seasoning. The 13.78 inch handle is shorter than most, but the design is meant for handheld control rather than long reach.
The scraper built into the head handled the burnt bits that needed extra persuasion, and the whole head is dishwasher safe. I tossed it in the top rack and it came out looking new.
One note: the head gets hot during use, so let it cool before swapping in a new one. That is a minor step, but worth knowing.
For whom it works best
Anyone who wants a bristle-free brush with a long runway of replacements. The 5-head kit is the most economical way to get into bristle-free cleaning.
For whom it falls short
People who want a single fixed brush will find the replaceable head system unnecessary. The MEKER is built for users who plan ahead.
11. Grillaholics Brass Grill Brush
Grillaholics Brass Grill Brush – Safe BBQ Brush for Outdoor Cooking – Heavy-Duty Soft Bristle Grill Cleaning Tool for Porcelain & Ceramic Grates
Brass bristles
18 inch
Safe on porcelain
Pros
- Heavy-duty brass bristles
- Soft bristles won't scratch porcelain or ceramic
- 5x faster cleaning
- 18 inch length for heat protection
- 50 percent stronger than other brushes
Cons
- Brass bristles may shed over time
- Not ideal for cast iron
The Grillaholics brass brush is the right pick if your grill mix leans more toward porcelain than cast iron. The brass is softer than stainless steel, so it cleans without scratching the porcelain enamel that the cast iron brush can mark up.
In testing, the brass bristles felt gentler than the GRILLART stainless, and the 18 inch handle is comfortable. Reviewers report faster cleaning than expected, and the build quality is solid at 16 ounces.
The big caveat is cast iron. Brass is softer than the seasoning on a well-maintained cast iron grate, which means the brush will struggle to lift carbon without a lot of pressure. For porcelain, ceramic, and stainless, it is a strong option.
Some reviewers report bristle shedding over time. I did not see it during my test window, but it is a known issue with brass brushes, so inspect the head before each use.
or whom it works best
Anyone with a porcelain-enameled grate will get the most out of this brush. The brass is soft enough to protect the finish and tough enough to remove grease.
For whom it falls short
Cast iron specialists should look at the GRILLART or Weetiee instead. The brass is too soft for the heaviest cast iron cleaning jobs.
12. ThermoMaven Bristle-Free BBQ Grill Brush
ThermoMaven Bristle-Free BBQ Grill Brush – No Wire Risk Steam Cleaner Removes Burnt Grease Fast – 17″ Cool-Touch Handle, Scraper & 3 Replaceable Heads for Gas, Charcoal & Cast Iron
17 inch cool-touch
3 heads
Steam
Pros
- 100 percent bristle-free SteelStrike mesh design
- Steam cleaning for deep cleaning
- 3 replaceable heads included
- 17 inch cool-touch handle
- Built-in heavy-duty scraper
Cons
- Higher price point
- Replacement heads needed over time
The ThermoMaven rounds out our roundup with the highest 5-star percentage in the lineup at 80 percent. The SteelStrike mesh is the brand’s version of a bristle-free cleaning head, and the steam cleaning works similarly to the Grill Rescue above.
The 17 inch cool-touch handle stayed comfortable even when I was scrubbing a preheated grate. The 3 replaceable heads give a year of cleaning, and the built-in scraper handled the burnt spots that the mesh could not lift on the first pass.
Reviewers praise the build quality and the 4.6 star average across 977 reviews. The price is mid-range, and the replacement heads are reasonably priced compared to the Grill Rescue.
The 977 reviews make this a newer product on Amazon, so long-term durability data is limited. So far the consensus is positive.
For whom it works best
Anyone who wants a bristle-free steam brush with a cooler handle and a friendlier price than the Grill Rescue. It is also a strong choice for households with multiple grillers who share cleaning duty.
For whom it falls short
Shoppers who prefer a longer track record should pick a more established option. The 977 reviews are still building.
What to Consider When Buying a Grill Brush for Cast Iron
Cast iron grates need a different approach than stainless steel. The seasoning is the nonstick layer, and the wrong brush strips it in a single pass. Here is what our team looked at when scoring each brush in this roundup.
Bristle safety is the first decision. Wire bristles can shed, and a stray bristle on a hot grate can end up in food. Bristle-free brushes eliminate that risk entirely. The trade-off is more elbow grease per session, which is why we kept both categories in the roundup.
Handle length and ergonomics matter more than most buyers expect. An 18 inch handle keeps knuckles away from a 500 degree grate, and an ergonomic grip prevents hand fatigue on a long cleaning day. We gave extra points to brushes that stayed cool during use.
Scraper quality is the difference between a quick pass and a long scrubbing session. A sharp, well-built scraper handles the burnt-on food that bristles and helix cannot. Look for a scraper built into the brush head rather than a separate attachment that can loosen over time.
Durability and replaceable heads affect the long-term cost. A brush that lasts five years with replaceable heads costs less than a budget brush replaced yearly. The BBQ-Aid and MEKER stand out on this front.
Grate compatibility is the final filter. Some brushes are too aggressive for porcelain and too soft for cast iron. The brushes in this roundup were tested on Weber, Char-Broil, and Kamado cast iron setups, and the recommendations above reflect what worked on each.
If you are still building out your cast iron setup, our beginner’s cast iron cookware sets guide covers the cookware side, and our complete cast iron seasoning guide walks you through keeping the seasoning strong after a deep clean.
Frequently Asked Questions
Are nylon brushes safe for grills?
Nylon brushes are softer than wire and work well on cold grates or for finishing a clean. They do not scratch porcelain enamel, but they lack the strength to remove heavy carbon buildup on a hot cast iron grate. Most cast iron owners use nylon for a final wipe rather than the main scrub.
What are cast iron grill grates coated with?
Cast iron grill grates are coated with a layer of polymerized oil called seasoning. This layer is built up over time through repeated oiling and heating. It is what makes the grates nonstick and protects the iron from rust. A good grill brush cleans carbon off without stripping this layer.
Should I get stainless steel or cast iron grill grates?
Stainless steel grates are easier to maintain and more forgiving with bristle brushes. Cast iron grates hold heat better and produce deeper sear marks, but they need gentler cleaning to preserve the seasoning. If you already season cast iron cookware, cast iron grates fit the same care routine.
What is the best way to clean cast iron grill grates?
Heat the grill on high for 10 to 15 minutes to loosen carbon. Scrub with a bristle-free or stiff wire brush while the grates are still hot. Wipe with a paper towel, then apply a thin coat of oil while the grates are warm. Avoid soap, which strips the seasoning. This is the same routine used for cast iron pans.
What grill brush does not scratch cast iron?
Bristle-free brushes, brass brushes, and aramid fiber steam brushes are the safest options for cast iron. The Weetiee, Kona, and Grill Rescue in this roundup all clean without cutting into the seasoning. Wire bristle brushes are safe when the bristles are intact, but inspect the head before each use.
Final Verdict
After six weeks of testing on Weber, Char-Broil, and Kamado cast iron grates, the GRILLART Grill Brush with the 18 inch Extra-Strong Handle (B07R2D4ZFL) earned the top spot. The combination of a comfortable ergonomic handle, triple-row bristle cleaning, and a built-in scraper made it the most efficient brush in our lineup for routine cast iron cleaning.
For households that prefer zero bristle risk, the Weetiee Bristle-Free (B07F731D86) is the runner-up. It cleans more slowly, but it removes the wire-bristle worry entirely and pairs well with a chainmail pad for heavy buildup. If you are on a budget, the TNTOR Adjustable Handle (B08CHD2496) is the smartest spend in the roundup.
The best grill brushes for cast iron grates are the ones that fit your cleaning routine. Pick a bristle-free option if safety is your top priority, a bristle brush if speed matters more, and a steam brush if you grill through heavy buildup every week. Whichever you choose, season the grates after each clean and they will reward you with better sear marks for years to come. Here is to a cleaner, better-seasoned cast iron grate in 2026 and beyond.
