How to Clean Grill Grates on a Santa Maria Grill
How to Clean Grill Grates on a Santa Maria Grill
Most articles about cleaning grill grates are written by people who sell grills that are hard to clean. That is not an accident. A grate that bakes on grease, warps in the heat, and rusts the first time it rains gives you a reason to come back for cleaners, brushes, covers, and eventually a replacement. The maintenance is the business model.
We build the other kind. After twenty years behind the line and a decade building fire, the grills we fabricate are heavy, open, and made to be wiped down in the time it takes the coals to settle. So this guide does two things. It tells you how to clean any grate the right way, and it shows you why most of the work people accept as normal comes from buying thin steel in the first place.

The Truth About Santa Maria Grill Maintenance
Here is the part the import catalogs leave out. Cast iron rusts the moment you neglect it and has to be re-seasoned every time you clean it hard. Porcelain coating chips, and once it chips it fails for good. Thin stainless warps under real fire and never sits flat again. Every one of those problems is a material problem, not a cleaning problem. You are not failing to maintain the grill. The grill was built to need it.
A properly fabricated grill removes most of that from your life. Heavy steel does not warp at asado temperatures. An open frame lets air and water move through instead of pooling. Bare, honest steel takes a burn-off and a scrape and goes back to work. The less a grill is built to sell you, the less it asks of you after the cook.
What Thin Steel Costs You Over Five Years
A cheap grate looks like a deal on day one. Then the bill comes due in pieces. A re-season kit here, a replacement grate there, a cover because the metal cannot survive a season outside, a wire brush that sheds bristles into your food. Stretch that across five years of real cooking and the imported bargain costs more than the rig that was built once and built right.
Heavy-gauge steel is the opposite trade. More upfront, almost nothing after. The weight that makes it expensive to ship is the same weight that makes it last. That is the whole argument for buying a real grill, and you can see it most clearly in how little it asks of you on cleanup day.
The Two-Minute Burn-Off
This is how we clean a working grate. No chemicals, no soak, no ammonia bag.
Step 1. Run It Hot
After the cook, run the grate hot for ten to fifteen minutes. On a Santa Maria, raise the grate, then drop it close to the bed of coals. The heat does the labor and turns grease and residue brittle.
Step 2. Knock It Loose
Knock the carbon loose with a coil scraper or a hardwood block. Skip wire-bristle brushes. They shed metal that ends up in the next meal. Half an onion on the tongs takes care of the rest.
Step 3. Wipe and Dry
Wipe with a damp cloth, then run the grate warm one more time to drive off the moisture. Done.
The reason this works on our grills and not on a flimsy one comes down to the build. An adjustable grate lets you clean hot and dry hot without putting your hands near the fire. A heavy grate holds that heat long enough to finish the job. Thin steel cannot, which is why the import guides send you to the pressure washer and the chemical aisle instead.

Food Safety Starts With the Material, Not the Cleaner
Everyone talks about cleaning the surface. Almost nobody talks about what the surface is made of, which matters more. A food-contact surface that chips, flakes, or sheds is a food-safety problem no amount of scrubbing fixes. As a ServSafe-certified chef, this is the part I will not cut a corner on, and it is the part the import catalogs are quietest about.
Three rules carry most of it:
- Use coil or wood tools on cooking surfaces, never wire bristles. Shed bristles are one of the most common grill-related ER visits in the country.
- Keep harsh chemicals for once-a-year restoration only, and rinse to bare metal afterward. They have no business near a weekly cook.
- Trust the material before you trust the routine. A surface that needs babying to stay safe was the wrong surface.
That last rule is exactly why we make the material decisions we do, and it is the reason the iron cross on our rigs is finished the way it is.
Why We Powder-Coat the Iron Cross Instead of Running Stainless
People assume stainless is the right call for anything near food, and on a grate they are right. A grate is a direct cooking surface. Food sits on it and sears against it, so you want bare, inert metal with no coating to fail. The cross is a different part doing a different job, and the material logic changes with it.
A whole lamb or a side of ribs gets pinned to the cross and stood up beside the fire. The meat is held at the pin points. It does not cook flat against the surface the way a steak cooks on a grate. The cross is structure. Its job is to hold heavy weight, dead level, through hours of radiant heat without flexing.
For that job we use heavy mild steel, not stainless. Mild steel is stronger in the gauges a cross needs, it holds the forged, blackened look the tradition calls for, and stainless at that size would be wrong in appearance and more expensive for no structural gain. Stainless earns its place on the grate. On the cross it solves a problem you do not have.
That leaves the finish, because bare mild steel rusts. So we coat the cross in a silicone-based, high-heat powder rated from 600 to 1,200 degrees, food-industry approved for indirect contact with food, with corrosion resistance tested past 1,000 hours of salt spray. That spec matches the part exactly. It survives the radiant heat of a live fire, it carries the correct food-contact rating for a holding structure, it resists animal and vegetable fat, and the 1,000-hour salt-spray figure means it holds up to the coastal and outdoor air that eats lesser finishes. The low-gloss black is also, and not by accident, the exact forged look the cross is supposed to have.
One material decision, matched to the job: corrosion protection, the right contact rating for a structure, live-fire heat tolerance, and the traditional finish. Stainless solves none of those better here, and costs more to solve them worse.
Built to Be Cleaned, Built to Last
Everything that makes our grills easy to clean and easy to keep is the same thing that makes them worth the price. These are standard, not upgrades.
Quarter-Inch Plate
Heavy steel that holds heat and does not warp, on an open bottomless frame that moves air and water instead of trapping them against the metal. A burn-off actually finishes the job.
This is not stamped tin. This is the last grill you will ever buy.
You can spend five years maintaining a grill that was built to be maintained, or you can buy one built to be cooked on. We make the second kind.
FAQ
How often should I clean my grill grates?
A quick burn-off and scrape after every cook. A deeper clean once or twice a season, depending on how hard you run it. On a properly built steel grate, that is the entire routine.
Do I need to re-season the grates on a steel asador?
Not the way you re-season cast iron. Heavy steel that gets a burn-off and a wipe builds its own working surface over time. The constant re-seasoning cycle is a cast-iron problem, and it is one reason we build the way we do.
Can I pressure-wash my grill?
On heavy steel, occasionally, for a deep restoration, then dry it fully and run it warm. It is rarely necessary. If a grill needs the pressure washer to stay clean, that tells you something about how it was built.
Is the iron cross safe to use with food?
Yes, for what it does. The cross is a holding structure, not a cooking grate. The meat is pinned at the contact points, not seared flat against the surface, and that incidental contact is exactly what the finish is rated for: a food-industry-approved, high-heat coating built for indirect food contact at live-fire temperatures. The surface your food actually cooks on is the grate.
What tools should I never use on my grates?
Wire-bristle brushes, on any grate, ever. Use a coil scraper, a hardwood block, or a halved onion. Shed bristles are a real and avoidable hazard.
